RE: A question on Http Connection obtained by WebdavResoruce

[Ritu Kedia]

Warwick,

Thanks for your reply.

The HttpConnection that I am referring to is 
method.releaseConnection() after the method is executed.

Calling this method would just close the current request and not re-set the
HttpClient state. In other words the HttpClient will still hold on to any
cookies from the previous handshake and the next Method execution would not
have to re-authenticate. So you would still be able to use the same
WebdavResource by setting a new path to perform another operation.
Calling releaseConnection may also be useful for uploading files with
Transfer-Encoding:Chunked. Certain WebServers/AppServers expect an explicit
client close connection as an indication for end of stream.

Could there be any other reason for not releasing the connection? Or is this
just an oversight?

Thanks,
Ritu

I believe this was a design choice to allow connections to be reused
(persistent connections) rather than opening/closing a connection on
every DAV method call. For example I have one webdavresource per thread
and reuse the webdavresource by making use of the setPath() command to
change the resource target for the webdavresource or by using the
methods that take a path to specify which resource is the target of the
method call.

A question on Http Connection obtained by WebdavResoruce

[Ritu Kedia]

Hello,

I was looking into a caching solution to cache the WebdavResource obtained
for a user so as to avoid the time taken to re-authenticate that user to
Slide App. In doing so I came across the way the HttpClient is managed by
the WebdavResource. After execution of any method the HttpConnection is not
being released. Is there any specific reason for this? 

On Commons HttpClient
site(http://jakarta.apache.org/commons/httpclient/tutorial.html) it is
mentioned that "It is important to always release the connection regardless
of whether the server returned an error or not."

If the connection is not released when will it be closed by default? I
believe that would depend on the ConnectionTimeout setting of HttpClient.
However I saw that in WebdavSession the timeout is not being explicitly set,
so the default value of 0 must be applied. In this case when would the
connection be closed? Would it then depend on the server timeout settings?
Anyone having any knowledge of these issues, please do reply.

Thanks,
Ritu

Subject: A question on TxFileStore configured with Binding Store


Hello All,

Is anyone using TxFileStore with BindingStore? I have a question on the way
the files are stored in the file system when using Binding Store. 

In Binding Store the resources are identified by a Unique Id instead of the
resource path and they are stored by the Id name directly under the store's
top level content directory configured in Domain.xml.

My question is that since all the resources are stored directly under a
single content directory will this not cause performance issues as the no.
of files grows very large? Please point out if I am missing something here
and if there is any config setting to create sub-directories under content
directory as the no. of files increases.

Thanks,

Does Slide support adding/removing Labels on Collections

[Ritu Kedia]

Hello All,

I would like to know whether Slide supports Adding/Removing labels on
Collections.

As per the DeltaV specs:
The request MAY include a Depth header.  If no Depth header is
included, Depth:0 is assumed.  Standard depth semantics apply, and
the request is applied to the collection identified by the
request-URL and to all members of the collection that satisfy the
Depth value.  If a Depth header is included and the request fails
on any resource, the response MUST be a 207 Multi-Status that
identifies all resources for which the request has failed.


I am using WebdavResource.labelMethod. But the resources in my collection
were not added the label. Could someone please clarify Slide's behavior?

Thanks,
Ritu

Question on Remove Label correct usage

[Ritu Kedia]

Hello All,

I have a question on the correct way of using WebdavResource.labelMethod for
removing a label.

boolean success = webdavResource.labelMethod(**path**, "label",
WebdavResource.LABEL_REMOVE)

In the above method "labelMethod" should **path** be the version path or the
resource path? In other words should **path** be something like
"/slide/history/1/1.0" or can it be "/slide/files/testingRemoveLabel.file".

I tried using resource path (i.e. "/slide/files/testingRemoveLabel.file"),
but it threw a 409 error. My resource has 2 versions: 1.0 and 1.1 of which
version 1.0 has been labeled. Ideally I expected the labelMethod to remove
the label from any version which has that label, given the resource path.
Could someone please point what am I doing wrong?

When I try removing label using the version path, of the specific version
which has that label, then it works fine. But this unnecessarily requires me
to first find which version has a given label. Am I missing something? 

Thanks,
Ritu

RE: Choosing between multiple namespace and multiple stores

[Ritu Kedia]

One big advantage of multiple namespaces is complete isolation of user,
history, roles, etc. all stores. I am not sure whether this is achievable
with multiple stores as well. At least with reference to the current thread
going around regarding incompatibility between history-collection-hack and
history folder separation per store, it appears that separating history
folder will not be possible (given that history-collection-hack is as good
as mandatory).

I tried configuring multiple namespaces by defining 2 servlets in web.xml
both using the same WebdavServlet Class.

webdav_ns1
Slide DAV Server

org.apache.slide.webdav.WebdavServlet

namespace
ns1

...


webdav_ns2
Slide DAV Server

org.apache.slide.webdav.WebdavServlet

namespace
ns2

...


webdav_ns1
/ns1/*


webdav_ns2
/ns2/*


In Domain.xml I have the 2 namespaces ns1 and ns2 defined. There is one
store defined in each of these namespaecs with the scope of the stores
defined as "/". I am able to access the 2 namespaces using:
http://hostname:portno/slide/ns1 and  http://hostname:portno/slide/ns2

I am even able to add resources and view them from either namespace. But the
resources are internally being added to and retrieved from the store
configured for the first namespace. So I see the same view from either
namespace. I am not sure whether this is a bug or there is some error in my
configuration.

Is anyone using multiple namespaces or has any knowledge about how they
should be configured? Please reply.

Thanks,
Ritu

I asked the same question a little while ago. It sounds like the
advantages of using one configuration over the other are not entirely
clear. Multiple stores are much easier to configure than multiple
namespaces, so I would probably go with this configuration. I suppose
that using multiple namespaces might give you more control if you want
these namespaces to behave very differently (e.g. with regards to
versioning, permissions, etc.), but then again I don't really know.

RE: Need help: Facing Connection reset: Read timed out: problem w hen invoking any method on WebdavResource after PUT

[Ritu Kedia]

Thanks a lot for the quick reply Ingo.

After sending out my first mail I did a small test: I explicitly closed the
HttpConnection at the end of the Put Method.
More specifically: I added the following lines at the end of the putMethod
of WebdavResource:
closeSession();
client = getSessionInstance(httpURL);

And yeah this fixed the problem. 

I don't have much experience with HttpUtil. I have a couple of questions:
1. What should be the expected behavior? Should the session have been closed
by default or is it something the program has to do explicitly?

2. Why does this problem surface only in case of Weblogic and not JBoss?

3. Will the above fix cause any other issues?

4. Is there any other better fix for this issue?

Thanks again,

The first thing that comes to my mind is that Weblogic might not be able to
handle the chunked transfer encoding correctly that is used when your
upload source is a stream. It looks like it cannot detect the end of
the request body.

I would rather expect this to be a Weblogic problem than a bug in
Httpclient since the latter doesn't give any problems with other
servers.

Need help: Facing Connection reset: Read timed out: problem when invoking any method on WebdavResource after PUT

[Ritu Kedia]

Hello all,

I am accessing Slide Server via Slide Client API (using WebdavResource).
Slide is deployed on Weblogic App Server. I am facing a "Connection reset :
Read timed out" issue when accessing any method of WebdavResource after PUT
method. Has anyone faced a similar issue or has any idea of what is causing
this issue? 

Things to note:
-- This error comes only when executing any method immediately after PUT.
I.e. If I execute "putMethod" followed by a "proppatchMethod", I see the
below stack trace.
-- But very importantly the putMethod itself goes fine and the file gets
uploaded to Slide server.
-- It does not happen when executing any other 2 methods in succession. For
e.g. if I execute "copyMethod" followed by a "proppatchMethod", everything
works fine.
-- This error is only on WebLogic. It works fine on JBoss APP server.

It looks like this has something to do with the fact that the PUT method
uploads a data stream, which is not being handled correctly by either
WebLogic server or HttpClient (the way weblogic expects it).

I am pasting the stack trace of the Weblogic Server. Please help, if you
have any idea. This is urgent for me. Any suggestions are also very welcome.

Hi 

 I trying my first example ever with SLIDE and doesn't seem to get it
right.

I get a "followRedirects is disabled" response, but have absolutely no
idea why. So any help would be appreciated.

 

My aim is to access MS Exchange server so that I can update the public
folder for example. And of course if you have a better alternative to
accessing MS Exchange, then I'm more than happy to listen to any
suggestions. I have only found the Compoze-library which costs a lot of
money, and then SLIDE which I'm trying to use now.

 

The source code is as follows:

 

package com.tobias.webdav;

 

import java.io.File;

import java.io.IOException;

import java.net.MalformedURLException;

 

import org.apache.commons.httpclient.HttpException;

HttpURL("http://oden/exchange/tobias/Notes";);

  hrl.setUserinfo("tobias","lindae77"); 

  WebdavResource wdr = new WebdavResource(hrl);

  File fn = new File("remote-file");

  String arr[] = wdr.list();

  int i=arr.length;

  while( --i >= 0 ) {

System.out.println( "["+i+"] "+arr[ i  ] );

  }

  wdr.close();

  }

  catch(MalformedURLException mue)

  {

  System.out.println( "exception "+mue );

  mue.printStackTrace();

  }

  catch(HttpException he)

  {

  System.out.println( "exception; "+he );

  he.printStackTrace();

  }

  catch(IOException ioe)

  {

  System.out.println( "exception; "+ioe );

  ioe.printStackTrace();

  } 

  }

 

}

 

 

Output when I run the program above:

RE: New checked-in property class to submit

[Ritu Kedia]

Hi Warwick,

I had the same issue sometime back about fetching the history uri of the
last checked in version (the report method not returning a sorted list of
versions). Coincidentally my first solution was just the same as what you
did, i.e. add a CheckedinProperty class for retrieving the href element of
the checked-in property :) But I realized that this is a generic problem for
any property which has xml value and so here is the solution I adopted:

Vector properties = new Vector();
properties.add("checked-in");
String lastCheckedInVersion = null;
Enumeration e =
getWebdavResource().propfindMethod(resourcePath, DepthSupport.DEPTH_0,
properties);
if(e.hasMoreElements())
{
ResponseEntity resp =
(ResponseEntity)e.nextElement();
Enumeration props = resp.getProperties();
if(props.hasMoreElements())
{
BaseProperty prop =
(BaseProperty)props.nextElement();
if(prop.getLocalName().equals("checked-in"))
{
NodeList list =
prop.getElement().getElementsByTagNameNS("DAV:", "href");
if (list != null &&
list.getLength() > 0 ) 
{
lastCheckedInVersion =
list.item(0).getFirstChild().getNodeValue();
}
}
}
}

return lastCheckedInVersion;

This approach could be used for any xml property value (for e.g. Labels)

Regards,
Ritu

property that the returned property value isn't being unwrapped from the XML
response correctly. The value returned for the checked in property is the
entire  element within the "checked-in" element definition rather than
the value of the href. I noticed that the owner property is the same and
that in the case of the owner the XML response is further decoded and the
actual value is returned. So I've defined an additional property class
called CheckedinProperty that behaves like the OwnerProperty class so that
only the value of the href (the latest history URI) is returned.  If you
don't see any problems with this then I'd like to know if it can be
submitted to the slide 2.1 head.
 
I've actually created an HrefValuedProperty base class that extends the
BaseProperty class as OwnerProperty does now and moved the common
functionality of the Owner and CheckedinProperty classes to this common
class. The OwnerProperty and CheckedinProperty now extend this class and
define only their TAGNAME and a constructor. If there are more properties
that could benefit from href decoding then they could also extend the
HrefValuedProperty class.

Version of commons-httpclient.jar

[Ritu Kedia]

Revisiting this old mail... I really really need this information as part of
our company policy. I went through the old httpclient archives
http://archive.apache.org/dist/jakarta/commons/httpclient/binary/ and
downloaded all the files from 
Jan-16-2004, Feb-15-2004, Feb-17-2004 and May-17-2204. There is no binary
available between Feb-17 and May-17. And the ones from these 2 dates don't
match in size with the one used by slide-2.1.M1 (whose date is 02-24-2004).
Has it been compiled from source code dated 02-24?

I really request the one who knows anything about this jar version, to
please respond. 

Thanks,
Ritu

I'd be interested too.
The CVS log shows that the last checkin was done on 02-24-04 by Daniel.

Is this going to be version used by 2.1 Beta as well?

RE: Has anyone seen connection warnings when deploying slide in a n App Server(JBoss)

[Ritu Kedia]

Hi Oliver,

I think you may have some idea about these warnings:
WARN  [WrappedConnection] Closing a statement you left open, please do your
own housekeeping

They appear when deploying slide in JBoss. Seems like some Slide db
statements are not being closed. Could you suggest something that I should
try to suppress these warnings? 

Thanks,
Ritu

Not sure I understood what you imply by the static block. But anyways are
you referring to suppressing the client side warning messages or server
side? I was referring to the deployment time warnings thrown by the App
server, which I don't think have any relation with slide logging. Since I am
using J2EE store, the App Server's Wrapped Connection is throwing these
warnings. May be some slide DB methods are not closing the statements before
returning.

Have you faced a similar problem? If yes, what is the error message you see?

Ok,

I think slide uses common-logging API to print the warning messages.

Just supress them. 

May be something like this

 static Log log;
static
{
log =
LogFactory.getLog(org.apache.commons.httpclient.HttpClient.class);
}

But not sure. You should see the API referces for this

RE: Problem disabling slide authorization

[Ritu Kedia]

Alon,

Your problem could be solved by turning auto-create-user on in domain.xml
(true)
This would ensure that if the principal is not already there in slide db
then one would be created prior to executing the requested method.

Hope this helps.

Regards,
Ritu

So after letting this sit for just a little bit, it strikes me that
this may be considered a bug in SecurityImpl (or the calling Method
implementations). The Methods are calling getPrincipal() so that they
can set the owner metadata in the node being created. When security is
off but webapp security is on, there is a Principal in the
CredentialsToken but it does not exist in the store. So you get an
ObjectNotFoundException.

If SecurityImpl finds a Principal in the CredentialsToken but not in
the NodeStore, why not return a SubjectNode with the principal name as
the path? Or do this if slide security is disabled?

For now the intention is to only suppress the messages. But if the same

RE: A question on security configuration

[Ritu Kedia]

:( ... The distinguishing factor in my requests is neither the user
credential nor the resource being accessed. The same user should be able to
access the Slide Repository either via my WebService or via
MS-Word/Excel/etc. I.e. The same user could access the same resource in
either mode. When accessed via WebService, my application is doing the
authorization. When accessed directly, I would have to override the default
slide security implementation with my custom implementation. 

I think I would have to try the clustering solution only with my custom
security implementation (since the direct slide access should also follow
the same security checks as done in my application). But I won't be able to
get to it may be for another month.
A couple of questions regarding custom security implementation... 
1. Is the security implementation class configurable via Domain.xml? There
is a security store configuration in Domain.xml but I haven't seen the entry
for the security helper class.
2. Which methods would have to be implemented if I am interested only in the
authorization checks and not the assignments?

Ritu

Done a little more thinking about this. I think separate namespaces 
sounds like a good idea, but there may be a problem. Since the Store 
configurations are per-namespace it's likely that the ExtendedStore 
cache will be per namespace as well. If this is the case then you're 
back to a situation where you'll need clustering to keep the caches in 
sync. Unless you really want everything to run in the same webapp you'd 
probably be better off just running a cluster with two nodes.

Stefan's suggestion gave me an idea, though (several actually). What you 
really need is a way to bypass the security checks in SecurityImpl based 
on some aspect of the request. I went through several ideas involving 
extending WebdavServelt or Domain to provide different 
NamespaceAccessTokens with different Security implementations based on 
where the request came from. This should be viable, but as I was writing 
this I realized that simply providing your own Security implementation 
that always returned true for a specific user should be enough. You'll 
still need to authenticate to the app server as that user, but since the 
Security implementation doesn't actually do any checking it should speed 
things up. For requests that aren't from the special user come in your 
implementation can just call ACLSecurityImpl (or another implementation) 
to do the checking, which should add very little overhead to the 
existing system.

I recently thought about a "scoped SecurityImpl" because we want
to have different security checking mechanics on different scopes.
On one scope we want to use Slides ACL Security and on an other
we want to use the Security checking of our own system.

We could of course have a SecurityImpl that permits all actions.

But I'm not sure that meets your problem, because your need to use
different scopes.

BTW how does JAAS decide what client currently accesses the webdav server?

RE: what is J2EE store??

[Ritu Kedia]

I can't infer much from "Error instantiating OracleRDBMSAdapter". Could you
provide the stack trace? One thing that I observed below is that the class
name in error message is OraclRDBMSAdapter instead of OracleRDBMSAdapter
Could that be the problem?
 
Regards,
Ritu
p.s.: please include Slide User List as well; you never know when the help
arrives from unexpected quarters :). Moreover this info could be useful to
others too.

Hi Ritu,
 
I am into designing pahse for the development of a web application using
WebDAV protocol.
The main functionality that I have to check are as under:-
1) The WebDAV server must interact with our repository (Oracle 8.1.7).
2) The WebDAV server must work with WebLogic app server.
3) The app server (WebLogic) shd. implement WebDAV protocol and basic Delta
V protocol
4) The WebDAV server shd authenticate users and requests against the
database.
 
I tested the following things with the WebLogic Server 8.1:-
 
a) I created a security realm for user authentication on WebLogic Server
using BASIC authentication.
I configured the security role in web.xml and weblogic.xml so that only a
particular user can access the resource.
 
b) I want to check up whether WebDAV server can establish Connection with
Oracle 8i database using WebLogic.
Since in slide version 2.1 b has OracleRDBMSAdapter, it gets compiled, but
on deployment of slide.war it gives me error like 
"Error instantiating OraclRDBMSAdapter". 
 
Can you please tell me how to use connection pooling using Slide J2EE store
so that I can access Oracle 8.1.1 database?
I just want to ensure (point no. 1 above) before starting development of
this WebDAV application, whether WebDAV server can interact with Oracle.
 
I would be grateful to you if you can provide me some hint.
I can also available online on [EMAIL PROTECTED]

Hi Dharmesh,
 
Yes I did test it... but currently I am off that work.. Here are the details
of what I did:
I was using Slide 2.1M1 (not yet tested 2.1B1), with Oracle 9i. I configured
the slide pool and datasource in weblogic and added the resource-ref to
web.xml and the corresponding resource mapping to weblogic.xml. The Slide
deployment went fine, and I could perform WebDAV operations from DAVExplorer
client. However I was facing some problem when accessing slide from inside
my application (using their webdav client lib). I didn't get time to look
into that.
 
If you give me more details of the nature of the problem you are facing,
then perhaps I could help.
 
Regards,
Ritu

Ritu,
 
Have u configured j2ee store on WebLogic Server 8.1?
 
I would like to deploy Oracle database (Oracle 8.1.7) driver on WebLogice
Server 8.1.
 
In the mail list I found that you are also working on slide using WebLogic

RE: A question on security configuration

[Ritu Kedia]

I very much appreciate your taking the time to think about the different
issues that people have (I have seen you giving great suggestions on a lot
of other issues too). Definitely thanks for your help. 

The second suggestion that you gave below about clustering, is exactly what
I was thinking of. But as you pointed out that it is a new feature and *very
untested*, I would opt for that solution as a last resort. At this point I
am looking for a very quick and sure shot solution. I was just hoping that
may be slide.properties could be configured per namespace. Alas I don't
think thats possible, at least with the current implementation.

One question on performance impact due to security checks: what is the most
time consuming aspect of slide security? Is it the enumeratePermissions
method? 

Regards,
Ritu

Ok, so you don't like my ideas :).

I've never played with namespaces, so that could be a good option and I 
wouldn't know it :). However, since security is controlled in the 
slide.properties file you're probably going to need a completely 
separate instance of Slide.

So my *new* suggestion is to try running two instance of Slide in a 
cluster, one with security and the other without. There's info for how 
to configure this on the Wiki. Clustering is very untested at this 
point, so if you've got the time it would be great if you could put it 
through its paces :).

RE: A question on security configuration

[Ritu Kedia]

Thanks for the reply James.

Your approach has 2 problems:
1. The most important one is : I want to avoid slide security checks for
performance reasons and specially since I am already doing the
authorization, I definitely want to avoid slide side overhead.
2. Even if I ignore performance, I still face a problem with the user info
logging against every activity. In other words I lose the information about
who uploaded the file/locked it/checked it in.

What about the namespace solution... is it possible to configure different
security properties for a different namespace in the same App Server
instance?
Or could you suggest some other alternate whereby I could turn off security
checks when accessed from a particular client?

Ritu

Ritu,
One option might be to have a user account with all access to every node

A question on security configuration

[Ritu Kedia]

I am using Slide in 2 modes:
1. From within my Application, in which case my application acts as the
entry point for a client.
2. From a third party client, in which case Slide is the entry point for the
client.

Slide is accessed from within my application using the Slide WebDAV client
lib. Whereas it is accessed from the third party client via WebDAV (e.g.
WebFolders in MS).
In both these cases, the authentication is done using JAAS. And
authorization depends on the mode of access. When accessed from within my
application, the authorization will be done by my application but when
accessed directly from a 3rd party client, the authorization should be done
by Slide's security support. In other words, my requirement is to turn off
Slide's security in one mode and turn it on in the other mode. Both modes
would be active simultaneously. Could someone please provide me any
hints/help with designing a solution for the above requirement?

One thought is to have 2 different namespaces, one for each of the above
mode. Both these namespaces would access the same store but would have
different security configurations. Is this achievable? I think this depends
on whether slide.properties is applicable per namespace or per domain. If
anyone has implemented such a solution, then please do let me know.

Ritu

RE: Having problem in using Slide's Bind function

[Ritu Kedia]

Did you create a new schema and did the first time Slide deployment with
BindingStore in Domain.xml? If not, I think that should solve the problem.
You cannot switch between BindingStore and ExtendedStore on the same schema.

Secondly, are you using auto-create-users feature? On 2.1M1 I faced a
problem with that feature on BindingStore. I had to do a local fix to get
that working. Not sure whether that bug still exists in 2.1 B1.

Hi Slide guys,
 
We are trying to use Slide's Bind function to create links for folders.
Following the tutorial, we did the following:
1. Add classname="org.apache.slide.store.BindingStore" to store
configuration.
2. Add org.apache.slide.binding=true to slide.properties
3. Remove all the existing folders (store and work)
 
Then we start the silde server (2.1b1). Everything seems all right. We've
noticed
several xml files have been created under /store/metadata, like
1093232302952.0.def.xml.
After that I use slide client tool to connect to server and try to create a
folder
under files folder (this user is of root role). However, we will get a "Not
Found (404)"
error. 
Then I tried to remove the classname="org.apache.slide.store.BindingStore"
from
store configuration and then try creating subfolder again. It will work
well. I'd like
to know whether any of you have met this kind of problem before? How to
solve this problem?
Thanks in advance.

RE: OracleRDBMSAdapter no longer supportted?

[Ritu Kedia]

Co-incidentally I was testing Oracle Store with WebLogic and I came across
another issue with the storeContent implementation in OracleRDBMSAdapter.
The following line throws ClassCastException:
OutputStream out = ((oracle.sql.BLOB)
blob).getBinaryOutputStream();
Because weblogic is wrapping the blob in its own blob wrapper class:
"weblogic.jdbc.wrapper.Blob_oracle_sql_BLOB".

I think what Kiran did was test Oracle Store with storeContent
implementation of DB2RDBMSAdapter. I tried the same on Oracle 9i and it
worked fine. 

So I think the storeContent implementation of DB2RDBMSAdapter should be
moved to CommonRDBMSAdapter and used by Oracle as well. This transition
would even remove the compile time dependency on oracle driver libs.

Also, another important thing... there was a patch applied by Davide for
Content-length to Oracle Adapter (storeContent method has the fix: bugId
30317). That fix should be applied to CommonRDBMSAdapter.

Ritu

In CommonRDBMSAdapter there isn't a storeContent method...
If I remove the storeContent method in the Oracle adapter (thus using 
storeContent in StandardRDBMSAdapter) with 10g and classes12.jar or 
ojdbc14.jar I get this error:

ORA-01461: can bind a LONG value only for insert into a LONG column

I haven't 9i installed so I can't try with it.

RE: Odd behavior with getChildResources of a Collection on WebSph ere

[Ritu Kedia]

Thats fine Stefan. Thanks for your time.

The default-servlet=false and url-pattern=/ works only with the Browser not
with any other client. In case of the browser, somehow the path is modified
to slide//files/etc don't know why the browser modifies the path. But it
works!

Anyways I think the problem should be fixed at WebSphere's end... they do
not set the correct servletPath in case of default servlet mapping in
web.xml (i.e. url-pattern=/). 

If I come up with some acceptable work-around, I will post to this list.

Ritu

Sorry Ritu, but I don't know much about WebSphere so I can't help
on this side.

But, to recall for me: with default-servlet=false and url-pattern=/
it works with other clients but not with slide client lib? If so,
may be we should make the client lib more tolerant?

RE: Odd behavior with getChildResources of a Collection on WebSph ere

Hi Stefan,

Thanks for your help.

I modified the url-pattern in the servlet-mapping to /* and redeployed Slide
App in WAS. But now I get "403 Forbidden: Invalid URI passed to Security
Collaborator" on accessing slide. My app context is /slide and the WAS
plugin-config.xml has mapping for /slide/*.

However one important point is that with url-pattern set to "/" and
default-servlet parameter set to false, I don't see the odd behavior when
navigating via Browser. See the following http trace:

Though on the browser I get "LocalTransactionRollbacked due to
setRollbackOnly" exception at the bottom of the folder tree.


Any idea of what could be going wrong or what else could I try?

The reason I had to set the default-servlet param to false was that with
url-pattern set to '/' in servlet mapping, the req.getServletPath() always
returns "/" and req.getPathInfo() returns the additional path info (for e.g.
files/ProjectArea), which I think is a bug in WebSphere 5.0.

Hi Ritu,

if you set default-servlet to false please use /* as servlet mapping
pattern.

i.e.
  /*
instead of
  /

I'm not quite sure that solves your problem but it solves the problem
with the double slashes.

Thanks for the reply Ingo.

I am on Slide 2.1M1

Some information that may be useful: On WebSphere WebdavServlet is not
recognized as the default servlet even though the url-pattern under
servlet-mapping, in web.xml is "/": /
I had to set the default-servlet init parameter to false.

Odd behavior with getChildResources of a Collection on WebSphere

[Ritu Kedia]

I have a slide deployment running on WebSphere with Oracle Store. I see an
odd behavior with getChildResources of a Collection: the collection itself
appears as one of its children. The same store when connected via JBoss or
WebLogic works fine. Could someone please help?
I read mail trail on similar issue with WebFolder on XP. But the cause there
was different:
http://www.greenbytes.de/tech/webdav/webfolder-client-list.html#issue-folder
-mismatch

I am not connecting to slide on port 80. I connect to it directly on the app
server's port, which in case of websphere is 9080.
HttpURL hrl = new HttpURL(username,
password, "mymachine", 9080, "/slide/");
WebdavResource wdr = new
WebdavResource(hrl);


If anyone could give me any hints... it would be great.

Thanks,
Ritu

RE: BindingStore Class Loading Error in JBoss App Server (Slide 2 .1.M 1)

[Ritu Kedia]

Thanks for your reply Oliver.

Yes I did check that no other jar in my JBoss has the BindingStore or the
org/apache/slide package. In fact I checked that no other jar on my machine
has that class or the slide package!! 
To rule out the compilation problems, I compiled the slide src code on the
machine which I am configuring.

It appears to me that there is a problem with the version of a third party
jar that ObjectNode/Uri or one of their imported classes, may be referring.
Could you please point out which third party packages I should search for? I
am really at a loss...:(

Ritu

Hmmm,

I have only come across such errors when I compiled something to one 
class/interface and on run time the implementation is different. 
However, the signatures seem to be equal. Have you checked you have only 
one jar that contains BindingStore in JBoss' class path? Anyway, I am 
not even sure this would cause problem...

BindingStore Class Loading Error in JBoss App Server (Slide 2.1.M 1)

[Ritu Kedia]

I am facing a Class loading error in JBoss App Server. I have spent
considerable time trying to figure the cause. Any help would be greatly
appreciated.

I get the following error when deploying Slide in JBoss App Server:

lang/String;) Incompatible argument to function


I am deploying Slide 2.1M1 on JBoss 3.2. I have successful deployed the same
version of Slide on the same version of JBoss before. I was trying to
configure another box with the same setup. I compared the versions of JVM on
the 2 boxes (the successful deployment and the one giving this class load
error); the JVM versions are the same: 1.4.2_02. I have compiled Slide 2.1M1
source code on my box.

Could anyone point out what I should look for?

Thanks in advance,

I use Binding Store too and everything seems to be working fine for me

WebdavResource and no problems so far. I have tested using my java app as
well as via DAVExplorer 0.90. 
Christophe>> One suggestion would be to test your server with another client
(may be DAVExplorer).

Hi Christophe,

have you set

I've tried to reproduce the behaviour that you described. I took Windows

Subject: stuck on slide


Hello,

I have downloaded the binary of slide 2.0 included tomcat 5.0.19.
I was able to run the startup.bat and view/log-in through
http://localhost:8080/slide and see a listing.

I then ran my sample program (at bottom of this e-mail) and saw
the output of WebdavResource exists, File is OK, and 
putMethod() Failed.

I then edited the web.xml file to only list the /files directory.
through the web and http://localhost:8080/slide I see that the
directory is currently empty and have nothing in it.

I then ran my sample program again, and got this exception:

My questions are: why is putMethod() keep on failing on me? And 
why do I get the exception error when I modified the web.xml to
only list /files?  Why is that I am able to see the web page after
I modified the web.xml but yet my sample program fails?

Here is my sample program::
import java.io.*;

import org.apache.commons.httpclient.*;
import org.apache.webdav.lib.*;

public class SlideTest
{
   public static void main(String args[])
   {
  try
  {
HttpURL hrl = new
HttpURL("http://localhost:8080/slide/files";);
 hrl.setUserinfo("root","root");
 WebdavResource wdr;
 wdr = new WebdavResource(hrl);
 if(wdr.exists())
System.out.println("WebdavResource exists");
 else
System.out.println("WebdavResource does NOT exists");

 File f = new File("SlideTest.java");
 if(f.exists())
System.out.println("File is OK");
 else
return;

 if(wdr.putMethod(f))
System.out.println("putMethod() Successful");
 else
System.out.println("putMethod() Failed");
  
 System.out.println("End of Test");
  }
  catch(Exception ie)
  {
 ie.printStackTrace();
 System.out.println("Cause " + ie.getCause());
  }
   }
}

Thanks for any kind of hints or pointers you might offer.

Advise needed for a Single Sign-On solution for Authenticating Sl ide

[Ritu Kedia]

I have deployed Slide in the same App Server as my Business Code which uses
Slide's Client Library. Since Slide will always be accessed via my
Application, which gets authenticated by the App Server Container, I would
like to pass the same session information to WebdavResource to connect to
Slide Repository. I am associating the same Realm with my Business
Application and Slide Server. Can anyone give me any hints on how to achieve
this?

I was thinking on the lines of passing the session information (cookie or
jsessionid) available with my Business App to the WebdavResource via
HttpURL. But HttpURL does not have any methods to add cookies. So I
experimented with URL rewriting by passing the jsessionid in the URL. This
did not work. 
I constructed the HttpURL as follows:
HttpURL hrl = new HttpURL("localhost", 8080,
"/slide;jsessionid=xxx")

Any suggestions/ideas?

Regards,
Ritu

RE: Facing problem with version-controlling a resource created by Cop y method in BindingStore

[Ritu Kedia]

Thanks Ingo for looking into this.

The byte array solution is not acceptable due to memory constraints. 

I had apprehensions about available method, which you confirmed. You are
right that a server side solution is the correct fix. If you have already
filed a bug for this, please let me know or else I will file a bug. 

If someone familiar with the code could get to this before the 2.1 release,
it would be very much appreciated.

Forgot to say, if you need a workaround now, just read the content into
a byte array and pass that to putMethod().

[Ritu Kedia]

Ingo,

I have a client side fix for it, which I tested and it works fine. I have
created a patch for it on the latest WebdavResource obtained from CVS Head.
Could you please take a look at it? I am attaching it here.

The fix is basically computing the length of the data from the InputStream
by using *available* method.

Ritu

Subject: Re: Facing problem with version-controlling a resource created

This looks like Slide fails to compute the getcontentlength if a
resource is PUT using "Transfer-Encoding: chunked". In fact there are
statements in PutMethod that look like this:

revisionDescriptor.setContentLength(req.getContentLength());

This is not sufficient. When using chunked transfer-encoding the
content-length has to be computed from the data actually received.

Anyone wants to file a bugreport?

RE: Facing problem with version-controlling a resource created by Cop y method in BindingStore

[Ritu Kedia]

On further investigation of this matter, I found the source of the problem
with versioning a copied resource. 
I am creating a resource using:
WebdavResource.putMethod(String path, InputStream fileStream)
This creates a resource fine but the *getcontentlength* property of the
resource is set to -1.
Therefore when I copy this resource, there must be some problem though the
copy call returns fine without any errors.
I face an error only when I try to version control this copied resource.

I am certain about the cause of the bug (which is getcontentlength property
being set to -1), because I tested by manually modifying the
getcontentlength property and then repeating the steps of copy and
versioncontrol. It worked fine.

This getcontentlength property bug happens only when using InputStream with
putMethod. When using File argument, everything goes fine.

Does anyone know the fix for this bug? 

Thanks and Regards,
Ritu

RE: Checkin and checkout

[Ritu Kedia]

:)... I have seen this question being asked so many times. I had myself
asked the same questions some time back...Just a piece of advice from
personal experience.. it would be of help if you refer the Webdav and DeltaV
specs when in doubt about any specific behavior.

Checkout just marks the resource as being checked-out. When another user
tries to checkout the same resource s/he gets a conflict error. So yes you
would have to explicitly get the resource for downloading it locally.
Similarly Checkin just creates a new version and unmarks the resource.
You could perform n no. of resource modifications between checkout-checkin
(using PUT or PROPPATCH), without creating a new version. In other words,
after checkout a new version will be created only when the checkin is
called.

Ritu

Hi Ritu,
 
Yes. It started working after I set auto-version-control  to true in
Domain.xml.
 
I have some more queries.
For Checkout and checkin methods, there is only one parameter path.
Generally after checkout, we need to get working copy. Where does slide put
this?
Do I have to do explicit get after checkout?
Similarly for checkin, how do get the updated file in?
 
Thanks,

The following property should be set to true.

Most likely that should be true since you say that you haven't changed
default properties.
Next your resource should be "put under version control" for
checkin-checkout to work. Use WebdavResource.versionControlMethod.
You could also set 
true

in Domain.xml, if you want every resource to be versioned by default.

Auto Create Users is not working with BindingStore

[Ritu Kedia]

On further investigation of the problem described below I observed that the
default users(root, guest) are being created. Sorry.. I was confused on the
first look at the URI table which had some nos (i.e. /1087541713531.0) in
the URI_STRING column instead of "/users" as in case of ExtendedStore. 

But this still leaves me with the problem of auto-create-users. This
functionality is not working with BindingStore. I observed that the new
users are being created in the URI table but the BINDING and PARENT_BINDING
tables are not being updated. Has anyone faced similar problem? I am using
Slide 2.1M1 with Oracle Store.

If it would be helpful: I debugged the code path on making an OPTIONS method
call to the Slide server with a new user. Here are my findings: The first
time the getPrincipal(SlideToken token) method is invoked on SecurityImpl,
the code path for creating a new user is entered since auto-create-users is
true. The *children* vector contains the newly added user and the
parentUri.getStore().storeObject(parentUri, object) call returns fine. When
the Slide server method returns, the URI table contains the new user entry
but the Parent_Binding and Binding tables do not have new entries for the
new user.   
Also via the code path(StandardRDBMSAdapter.storeObject(Connection, URI,
ObjectNode, boolean)) the bindings including the new user are being inserted
for "/users"... However the DB does not show those inserts on server call
return. Any idea of what could be going wrong?

Thanks for help,
Regards,
Ritu

RE: Overwriting Version Content/Properties

[Ritu Kedia]

Julian, Thanks for the reply.

You are right in that versions should ideally be immutable. But I think
having a server side feature of overwriting the content would be certainly
nice, specially in situations where the authors/developers can be trusted to
decide whether or not to overwrite (to avoid proliferation of unwanted
versions). 

With reference to your reply below: Is it at least possible to
overwrite/modify Live Properties of earlier versions without creating a new
version? I tried passing the history URI of a VCR to the PROPPATCH method,
with a "set" action for one of its live properties, but I got a
"cannot-modify-version" error (403 status). If its possible to overwrite
such client set properties, could you please tell me what WebdavResource api
to use and what path to pass?

Ritu

No. Versions are immutable (at least their content and their dead 
properties). That's the whole point of having a versioning system, isn't it?

I have yet another versioning question. I would really appreciate if you
could please answer the following:

The behavior that you have described below(i.e. multiple put and proppatch
after checkout without creating multiple versions) is part of the
checkout-in-place feature. Right? 

Is there any way to overwrite the content/properties of a particular version
without creating a new version?

As I understand, WebdavResource provides an "updateMethod" which copies the
content from one version to another. However my requirement is different, I
just want to overwrite the last version without creating a new version.
Basically I want to have the version tree but also give the user an option
to overwrite the last version.
I think I can achieve this by doing a checkout-put-checkin and then
overwriting the contents of the previous version with that of the newly
created version and finally deleting the newly created version (not sure
whether deleting versions is supported).  However even if this route is
possible, it is very cumbersome. 

Secondly, I tried updating/adding property values to a particular version
but got an error "cannot-modify-version". Is it possible to modify the
properties of an earlier version without forking/versioning?

Regards,
Ritu

Subject: Re: Adding Labels to Resource Versions


A CHECKIN does exactly what you cited: It effectively creates a new
version as a copy (content and properties) of the version controlled
resource.

To create a new version with different content than the currently
checked-in version controlled resource you first have to check-out the
VCR, than modify it with PUT and/or PROPPATCH and finally do a
CHECKIN. The previous version is not affected by this procedure.

RE: Adding Labels to Resource Versions

[Ritu Kedia]

Thanks Ingo

The labeling did work on the version href.

I have another versioning question: The checkin method does not take data
input-stream/bytes. Ideally I expected that a checkin would take the revised
content from the client for creating the new version.

I saw the DeltaV specs:

CHECKIN Method (applied to a version-controlled resource)

   A CHECKIN request can be applied to a checked-out version-controlled
   resource to produce a new version whose content and dead properties
   are copied from the checked-out resource.

The above comment suggests that the same content as the previous checked-out
version will be copied into the new version.
Given this, Slide is doing the right thing. But I did not understand the
rationale behind this. Shouldn't a "put" be implicit as part of a Checkin?

Given the way it works, does it mean that for checking in a new version I
will have to do an explicit put for the version URI just created by the
"checkin" method?

Thanks and Regards,
Ritu

You can add labels to and get a specific version. But you first have
to find out (via REPORT) where that version is located, because you
need to act directly on that version (yes, that's how WebDAV works).

And labels are supported by the server side of Slide.

Adding Labels to Resource Versions

[Ritu Kedia]

Need help with adding labels to specific resource versions.

I could not find a method on WebdavResource to add label to a specific
version of a resource.
The available methods are:
public boolean labelMethod(String labelname, int type)
public boolean labelMethod(String path, String labelname, int type)

Neither of these methods takes the version parameter. If I want to label
Version 1.0 of Resource1 as "Release 1.0" and Version 1.1 as "Release 2.0":
Is there server side support for this and could it be achieved via
WebdavResource?

Also, does WebdavResource support "Getting Resource" by version/by label?
(Again the getMethod takes only the path and no version or label parameter)

Thanks for any help

RE: JSR 170 available for Public Review

[Ritu Kedia]

Hi Stefan,

I was trying to get the RI of JSR170 under Slide's proposal module on CVS.
But the jcrri folder is empty. Is there an existing RI (other than the one
available with public review) or is it yet to be started? Also is there any
time frame for implementing JSR170 with slide as backend? I am particularly
interested in the transactional support.

the current implementation of the ri has no dependencies on slide. it is

remy sketched a possible architecture in his initial proposal:


- WebDAV powered JSR 170 client API
- WebDAV server layer, using JSR 170 API
- Slide core, providing a JSR 170 API


imo, such an architecture would make perfectly sense. but of course, the
community
has to come up with a strategy/decision regarding a future version of slide
& jsr 170.

RE: URL for getting a versioned resource

[Ritu Kedia]

Thanks Ingo for your reply.

Actually I was looking for defining a URL based on the resource path that I
see my resource under. That was more intuitive and meaningful, specially if
I have to pass that URL to a client to fetch the resource. I was wondering
if the Slide WebDavServlet's GET method already handles such request with
just a version parameter passed to it. In other words the GET method would
internally find out what is history folder where the resource version is
stored and fetch the correct version.

Ritu

If you want to know what versions are associated to your version
controlled resource, then use the REPORT method. That gives you the
hrefs (paths) of the versions and anditionally you can ask for
properties similar to a PROPFIND.

URL for getting a versioned resource

[Ritu Kedia]

I am looking for a way to construct a URL to get a specific version of a
resource.

For e.g. I have a doc1.txt in test1 folder in files collection. "doc1.txt"
is a versioned resource. I can get the original copy using URL:
http://server:port/slide/files/test1/doc1.txt

What URL should I use to get a specific version of doc1.txt? 

Internally Slide is storing versioned resources under history collection, so
I could get version #1.1 of doc1.txt using URL:
http://server:port/slide/history/1/1.1 (assuming that doc1 is under
history/1). However I wouldn't know which history folder my resource is
under and even I find that from the properties table, I wouldn't want to
construct such a URL.

Does the Get Command of Slide's WebDavServlet take a version parameter?
(such that I could use the following URL to get version 1.1 of doc1.txt:
http://server:port/slide/files/test1/doc1.txt?v=1.1)

Ritu

RE: what is J2EE store??

[Ritu Kedia]

J2EE store is any store that supports JCA. 

Slide's J2EEStore is for any RDBMS. You can deploy a database driver in the
App server and access it via Slide's J2EEStore.
Refer the App Server's manual for deploying DataStores.

For JBoss (when accessing from servlet side code): 

1. The sample files for the different databases are in docs/examples/jca
Copy the applicable ds.xml file to server/default/deploy and change the
properties to match those of your system.

2. In web.xml:
Add the following before 
   
   jdbc/DefaultDS
   javax.sql.DataSource
   SERVLET
   

3. In jboss-web.xml:

jdbc/DefaultDS
java:/DefaultDS


where DefaultDS is the jndi-name you provided in the ds.xml file above

For access from EJB you need to do similar setup in ejb-jar.xml and
jboss.xml inside meta-inf.

Also note that currently Slide uses only Connection Pooling of the J2EE
server and does its own TxMgmt. 
Hope this helps.

Ritu

Manual distributed Tx Mgmt in J2EE--> Manually managing Slide Tra nsaction + Custom DB operation as a single Tx

[Ritu Kedia]

Basically I want to club some of my custom DB operations with the Slide Tx.
For e.g.

Get Slide's UserTransaction
Get Custom DB Connection
Perform Slide Operations
Perform Custom Operations
Commit Slide's UserTx
Commit Custom DB Connection

In this scenario, if the commit of the custom DB operations fails, there is
no way to rollback Slide's UserTx (and vice-versa if I were to reverse the
order of the commits). The problem is that of a 2PC. Till Slide supports
plugging external TxMgr, is there a workaround to achieve this use case?

I defined a XADataSource in my J2EE server. It deployed fine. Is there a way
to access XAResource on this XADataSource inside the J2EE environment? I am
looking at the following:

Get Slide's UserTransaction
Get Custom DB XAResource
Perform Slide Operations
Perform Custom Operations
Custom XAResource.prepare()
if (above step returns success)
{
try {
Commit Slide's UserTx
Commit Custom DB Connection 
}
catch (Exception e)
{
Rollback Custom DB Connection
Rollback Slide's UserTx
}

}
else
{
Rollback Slide's UserTx
Rollback Custom DB Connection
}

I am unable to obtain XAResource on my XADataSource connection. The
container is returning its Wrapper DataSource which has no methods for
getting an XAConnection. Has anyone had a similar requirement? Please help.

Ritu

Linked Resources

[Ritu Kedia]

Does Slide support creating Linked Resources? More specifically, instead of
copying a resource from one collection to another, can I create a
reference/link to the resource? 
In other words, can the PUT command take the Source
URI(/slide/files/Folder1/Fiel1) instead of actual file contents?

I am not sure whether WebDAV has any support for linked resources.  Though
in the WebDAV specs (http://www.ietf.org/rfc/rfc2518.txt), I did read the
following:

4.6 Media Independent Links

   Although HTML resources support links to other resources, the Web
   needs more general support for links between resources of any media
   type (media types are also known as MIME types, or content types).
   WebDAV provides such links. A WebDAV link is a special type of
   property value, formally defined in section 12.4, that allows typed
   connections to be established between resources of any media type.
   The property value consists of source and destination Uniform
   Resource Identifiers (URIs); the property name identifies the link
   type.

12.4 link XML Element

   Name:   link
   Namespace:  DAV:
   Purpose:Identifies the property as a link and contains the source
   and destination of that link.
   Description: The link XML element is used to provide the sources and
   destinations of a link.  The name of the property containing the link
   XML element provides the type of the link.  Link is a multi-valued
   element, so multiple links may be used together to indicate multiple
   links with the same type.  The values in the href XML elements inside
   the src and dst XML elements of the link XML element MUST NOT be
   rejected if they point to resources which do not exist.

   

12.4.1 dst XML Element

   Name:   dst
   Namespace:  DAV:
   Purpose:Indicates the destination of a link
   Value:  URI

   

12.4.2 src XML Element

   Name:   src
   Namespace:  DAV:
   Purpose:Indicates the source of a link.


Does anyone know what is WebDAVs link property used for?

Ritu

RE: Which API should I use for a web app?

[Ritu Kedia]

Hi Andreas,

Could you please share the performance enhancements that you mentioned
below? Are those enhancements generic enough to be incorporated in Slide
2.0?

Also it would be great if you could provide more details of your
configuration in which you have 150,000 up documents?
More specifically I am looking at the following:
Which Slide APIs are you using (Server, Client, WVCM)?
What is the end to end configuration? (for e.g. DesktopClient --> WebServer
--> J2EE App Server --> Servlet --> EJB --> SlideServerAPI --> J2EEStore for
Metadata + FileStore for Content)
Is slide authorization turned on or off?
What store are you using for Metadata?
What store are you using for Content?
What is the average size of the documents?
What is the average depth of top most collection under /files?
What is the peak load (no. of concurrent users)?
Does your client do download of complete top level folders (recursive
download of all files in all sub-folders)? if yes, approximately how long
does it take for a top level folder with 1000 documents each being of approx
.5 MB?


Does Slide has test scripts for load tests? OR Has anyone written their own
test scripts to do the same?

Ritu

RE: Which API should I use for a web app?

[Ritu Kedia]

Daniel thanks really for all your feedback. 
Just one last question:

If I decide to use the Slide APIs directly and turn off Slide's Security
Checks using SlideTokenWrapper

SlideToken token = new SlideTokenImpl(credentials);
token.setEnforceLockTokens(true);
SlideToken tokenWrapper = new SlideTokenWrapper(token,true);
tokenWrapper.setForceSecurity(false);

And provide my own LockStore, since I will be maintaining user list in my
own Schema. Will this configuration significantly reduce the performance
bottleneck? Basically, is security check the main performance impairer?

Regards and Thanks,
Ritu

If the performance impact occurs inside the Slide Kernel, then how would it
be different when accessed via a Web-Client as opposed to a Desktop-Client?
The only difference is: in case of a Web-Client I would use some JSP/XSP and
in case of a Desktop-Client I would use some Web-Service.  With both the
JSP/XSP and Web-Services internally using the Slide Client LIB to access
Slide's WebDAV Service.

In your example above, when you say "retrieving data from Slide", do you
imply retrieving actual Content or retrieving any information: MetaData or
Content?
E.G. 1. if the client(Web/Desktop) wants to view all the sub-folders inside
a folder, a Slide WebDAV  command would be issued and the results would
be wrapped in respective format and returned to the client. 
E.G. 2. if the client(Web/Desktop) wants to download all the files in a
folder, a recursive Slide WebDAV  command would be issued and the
results would be wrapped in respective format and returned to the client.
Will there be performance impact in both cases or only case 2 (large
information download)?

Sorry for going into so much details... But I really did not understand the
difference between a Web-Client and a Desktop-Client. The security and lock
checks would be required in both cases. And most likely both cases would be
communicating with server over http.

When using the Client LIB, wouldn't there be a big performance difference
due to the additional HTTP communication layer introduced(I am referring to
using Client LIB from inside a JSP or Web-Service on the Server side)?
(Having the Slide APIs run in the same VM is acceptable).
However I think not having a clean separation between the WebDAV and the
Slide API layer would mandate the use of the Client or WVCM libraries.

RE: Which API should I use for a web app?

[Ritu Kedia]

Hi Daniel,

This thread was of great interest to me, because very recently I
experimented using Slide APIs directly from my Application. After reading
this mail thread, I am considering using Slide's Client APIs instead of
directly the server side APIs, though this would require me to code
separately for distributed transaction management (My App specific DB
operations + Slide operations --> in one atomic operation).

Before making the final decision, I wanted to confirm whether I understood
this correctly:

>BTW: Slide is (at the moment) far to slow to serve any webapp in real time.
>I'm currently working on a process engine that is doing all the caching 
>and background-building of webpages so that a webapp can be build on top 
>of slide. It will take some weeks until it is at a usable stage, but 
>this might be a choice for webapps in the future.

First of all: Why would Slide be used for building webpages? As I see it,
Slide is Abstract Content Repository, which in turn could map to multiple
physical Data Stores. In that sense, Slide is parallel to any other Data
Store when viewed from an Application's perspective. And so the only
difference is in the communication layer that an Application uses to
communicate with any other Data Store and that with Slide.
When you mention "background-building of webpages"... are you referring to
the fact that Slide communicates over the WebDAV(HTTP extension) protocol
and by that fact it would be required to return a webpage in response to any
request?
If yes, would that mean that the performance impact is due to the
communication layer between a WebApp and Slide? In other words, the
performance impact can be attributed to using Slide's Client APIs inside our
WebApp. And that could be avoided if we access Slide APIs directly from
inside our WebApp. Is this interpretation correct?

I have diagrammatically represented the above scenario(Slide being accessed
from a WebApplication). In this scenario do you see Slide being usable
(basically will there be any performance issue)?

My apologies if I misunderstood you.


Regards,
Ritu

Hi Ryan,
at the moment it is not recommended to use the slide api directly as you 
don't have access to many features that are hacked into the webdav 
layer. I don't know if versioning is working by using the slide api, 
there is some revision support but it is somehow mixed up with the 
webdav layer, so my advice would be not to use it. If you use slide api 
you are tied to the same vm so your webapp is not very scalable.
The client library is a good way to access slide as the webdav-layer 
will not change soo much in future.
WVCM is an abstraction layer on top of webdav, so it is little slower 
than webdav clientlib but it would be nice, if you would give it a try 
so that the jsr can get some feedback.
Regards,
Daniel

BTW: Slide is (at the moment) far to slow to serve any webapp in real time.
I'm currently working on a process engine that is doing all the caching 
and background-building of webpages so that a webapp can be build on top 
of slide. It will take some weeks until it is at a usable stage, but 
this might be a choice for webapps in the future.

Clubbing external XAResource with SlideTransaction

[Ritu Kedia]

Hello,

I have a requirement to define a custom XAResource (for our application
specific DB operations) and to club it in the same transaction as the
operations defined by Slide. For e.g. Creating a Collection + updating some
tables in my DB.

I am wrapping Slide's APIs in my server code. Inside my code I want hold of
current SlideTransaction to enlist/delist my custom XAResource. 

I looked into the slide implementation and the SlideTransactionManager
instance is held by the Namespace, which is not accessible to my
application. Is there a way to meet my requirement without locally modifying
the Slide Code? Any help would be greatly appreciated. I have an urgent
requirement.

Regards,
Ritu

RE: JBoss help

Something that may be useful to those using JBoss and facing problem with
explicit commits and rollbacks (as described by Igor in the first mail of
this thread):

Initially I had applied Oliver's patch (of committing the explicit commits
and rollbacks), to deploy Slide in JBoss. However that is not required if
you define the  of the DataSource in web.xml as "SERVLET". 
Sample:
   
   jdbc/slideDS
   javax.sql.DataSource
   SERVLET

but transaction log in 'work\content\dwarf\65\transaction.log'

This feature will not make it into slide 2.0 but perhaps in slide 2.x (x>0).

RE: File Get is not working (J2EE Store -- JBoss with MySQL)

[Ritu Kedia]

Hi Oliver,

I am using the ExtendedStore. The problem is not with the resource not being
delisted. 

The problem is that I had commented all explicit rollbacks and commits on
the Connection to make Slide run under JBoss. Therefore even though the
rollback method is called, the transaction is not being rollbacked.

Code Path: ExtendedStore.createRevisionContent -->
AbstractStore.createRevisionContent --> catch ServiceAccessException -->
delist contentstore with failure--> .. --> AbstractRDBMSStore.rollback

I am not conversant with JTA and J2EE connector specifications:: Under the
current Slide implementation is there a way to /?

It appears to me that Slide is using J2EE store only to maintain the
Connection pool and the complete transaction management is parallel to the
App Server's transaction management support. Is that right? If yes, is there
any plan to move to using the App Server's TM support?

Ritu

Hi Ritu!

I see, maybe we should just catch the IOException thrown by is.close() 
and silently ignore it?

Why the transaction is not rolled back completely, I do not know. Maybe 
the exception gets eaten up somewhere and does not come through.

Are you using the BindingStore? There might be an issue with it in

Not delisting the store with failure...

I figured the problem: 
Basically the "put" content was not going through fine. It failed in the
last step of store content. Therefore even though the Content was put in
Version_Content table, the Properties were never populated.


Slide Source: 2.0b1 source distribution
File: StandardRDBMSAdapter.java
method: storeContent
code snippet causing the problem: 
finally {
if (is != null) {
**is.close();**
}
}
cause of the above: statement.setBinaryStream(1, is, (int) contentLength);
closes the InputStream "is".

I am using MySQL Connector 3.0.10

This MySQL connector closes the InputStream on setBinaryStream:
http://www.mysql.com/documentation/connector-j/ --> 

I have fixed the problem locally by commenting the "is.close()". Everything
goes fine after the fix. 
Should I enter a bug for this? 

And this bug raises an important question about transaction management. The
"put" content should have been completely rollbacked. 

Regards,
Ritu

I have just done a create, put, get sequence and it worked just fine. No 
  idea what your problem might be, sorry...

RE: File Get is not working (J2EE Store -- JBoss with MySQL)

[Ritu Kedia]

Thanks Martin...>> There is a property entry "checked-in" which points to
the corresponding history file.

Back to my original question of performing "Get" operation:
Has anyone(who is using RDBMS Store) come across NullPointerException when
performing file "Get"?
I am using JBoss + MySQL... Apparently there is a bug with creating
non-versioned files: the "creationdate" property is not being created. After
I manually added this property to the non-versioned entry, the "Get" works
fine. 

(Note that the creationdate property is being set for the versioned history
files of the above non-versioned file. )


Slide Dev Team>> Has "Get" been tested with MySQL store on any other App
server?

Ritu

WebDAV versioning and slide versioning do not work that smooth together.
DeltaV is implemented on top of the slide API. The connection between
the resource at /files and the resources at /history are made by properties.

/files/foo.c has a property  "checked-out", which points to something
like /history/32212/1.1.
For the exact meaning of the related properties look into the
DeltaV specification.

RE: File Get is not working (J2EE Store -- JBoss with MySQL)

[Ritu Kedia]

Need some help in understanding the RDBMS Schema of Slide::

When we put a non-versioned file under version control a new URI entry is
made for the versioned counterpart (history/#)
How is the URI entry of the original non-versioned file bound to its
versioned counterpart ? In other words if the URI_ID of the non-versioned
file is 30 and that of the versioned-counterpart 35, then how are these 2
linked? The Parent_Binding and Binding tables show the association between
the parent collection and the non-versioned file but there is no binding
present between the non-versioned file and the history entry of its
versioned counterpart. Could someone please point out what am I missing?

Ritu

Hi All,

I am running slide 2.0b1 in JBoss_Tomcat integrated environment, using J2EE
store with MySQL DB.
The "create collection", "write file", "put under version control"
operations all go through fine. But I get a NullPointerException on "Get
file" operation.

Here is the top part of the stack trace:

I debugged the cause of this problem:

Has anyone faced a similar issue? 

I have a couple more questions (for the Slide team):
1. For a non-versioned file I don't see any entry in the Properties table.
When I put the file under version control, an entry gets created. (I am
looking by version_id picked from version_history table for the
corresponding uri_id)... Am I missing something?

2. After putting a file under version control I did 2 checkins and from my
WebDAV Client I see 3 versions in the version report: 1.0, 1.1, 1.2. But
in the version_history table I see only 2 entries for that file and in the
Properties table I see only one entry Shouldn't both the version_history
and properties table show 3 entries for that file?

3. What is revision_no in version_history table?

Is there any document explaining the Slide RDBMS schema?

RE: Connecting to Slide using DAV Explorer

[Ritu Kedia]

Thanks Martin!

The problem was with the web.xml... I created a tomcat project using eclipse
and as specified in the "Getting-Started With Eclipse" Slide Document, I
copied the web.xml from Slide Projects src directory to the web-inf
directory of the new Tomcat Project created by Eclipse. However the Web-Inf
folder under Tomcat installation had its own generated web.xml file (which I
did not suspect since it had the correct servlet mapping). 

If possible, someone from the Slide team should update the "Copy the
Domain.xml and web.xml files from the Slide source folder" section of the
doc http://jakarta.apache.org/slide/getting-started.html. Instead of "new
project's WEB-INF folder" it should be Tomcat installation's WEB-INF folder.

Thanks again,
Ritu
p.s. I truly appreciate the quick replies Feel very positive about
pursuing to use Slide as our base framework.

Did you enable authentication in web.xml? Slide will not do any 
authentication on its own. The servlet container will do the
authentication and some coarse grained authorization. 
Slide will ask the the container for the username and do fine 
grained access controll.

No sure about that and no server at reach, which uses default configuration.
But IIRC auto-version-control is disabled by default. Have a look at the end
of Domain.xml. Probably you must put the resource under version control
first.

RE: Connecting to Slide using DAV Explorer

I had tried this URL. But it failed with "HTTP Error or Server Timeout,
please retry the last operation".
Though this URL works fine through the browser.

I am using version 0.90 of DAV Explorer. Looks like a bug in that.

Versioning Support in Slide

[Ritu Kedia]

The Slide 2.0 Changelog says "Preliminary support for Delta V in the
client". What does this entail? 
More specifically is "Put under version Control", "Check Out", "Check In" of
resources supported?

Secondly, I have a generic WebDAV question regarding locking. From the Delta
V specs it appears that "Check Out" does not really lock the resource, it
only copies the resource to a workspace area on the server. Another user
could check-out the same revision in another workspace for parallel update. 
Does Delta V provide for Exclusive Locking of resources? If yes, how?

Thirdly, If check-out copies the resource to the workspace area on the
server side, does Slide provide for checking out the resource to the desktop
instead?

Lastly, does Delta V support checking out specific revisions? If yes, will
checking in of this resource insert the new revision after the revision
which was checked out?

Regards,
Ritu

RE: Connecting to Slide using DAV Explorer

Hello Martin,

I am using the JBoss_Tomcat combo (JBoss 3.2.1 and Tomcat 4.1)

I placed the slide war directory in the /server/default/deploy.
It deploys fine. What security setup needs to be done to avoid the NPE in
this deployment?

After reading your mail I tried deploying slide in Tomcat 4.1.27 (Tomcat
without JBoss). This time I can connect to the slide server from DAV
Explorer but I cannot perform any operation other than read. I get a
forbidden 403 error. This must be due to permissions. In Domain.xml I gave
"all" permissions to "all" users, but that did not help. 
I have 2 questions:
1. How do I login as root? (the open URL command does not take
username/password.. AND.. DAV Explorer is not prompting for username either)
2. How do I turn off security? I read
http://jakarta.apache.org/slide/conf-lib.html. But I did not understand
where is the default slide configuration file and how do I specify the
security property when starting tomcat.

Also it appears that Slide does not yet support versioning. I get a 501
error for methods Version-Control and Version-Report. Am I missing
something?

Thanks,
Ritu

This looks like a bug in Tomcat, not in Slide. 
At LogFilter.java:176 the filter calls java.security.Principal.getName(),
which returns null. The log filter does not check for null here. 

Which Tomcat version and what kind of authentication are you using?

You will most likely not want to upload anything to /slide/.

The actual content is stored in /slide/files/, so you should upload

following error message when trying to connect:

*DAV Interpreter:*
*500 Server Error*

And I can't locate server error log either.


I am new to Slide. I just downloaded code from *Slide_2_0_Release_Branch*
and built the tomcat project. I can access the Slide Home page:
http://localhost:8080/slide which gives the directory listings for /. I want
to test uploading files to Slide. 

The example.bat mentioned on the Slide Home page:
http://jakarta.apache.org/slide/examples.html, is not checked in CVS. 

I tried the commandLine Client but that is failing too:
[LOCALHOST] /slide/ $ put run.bat
put run.bat null
Uploading  'run.bat' to '/slide/': failed.
Internal Server Error (500)


Is this a server side or a client side error? Where is the error log
generated? 

Could anyone please point out where I am going wrong? Lastly does anyone
have a document on how to begin using Slide either via the DAV Explorer or
the commandLine Slide Client.

Regards,
Ritu

WebDAV support in CMS

[Ritu Kedia]

Hi All,

Slide seems to be the only open source CMS which is WebDAV enabled (unless I
am missing something).

However WebDAV seems to be a promising standard, which will greatly increase
the interoperability between the various third party WebDAV clients and
WebDAV enabled CMS. Then, how come no other open source CMS is standardizing
on this protocol? Most of CMS have their proprietary clients. 

I also saw the commercial Tamino WebDAV CMS white paper, which has a section
on the WebDAV support implemented by the various commonly used authoring
tools: Office 2000, Adobe 5.0, DreamWeaver, etc..., all major OS (Windows
2000, Linux, Mac OS X) and the embedded devices. After reading this
document, I was beyond a doubt that most of the CMS's must be WebDAV
enabled. But after having gone through the CMS matrix on OSCOM
http://www.oscom.org/matrix/index.html, I am unable to understand why no
other CMS is WebDAV enabled.

Surprisingly, Microsoft CMS 2000, does not mention the word WebDAV anywhere
in its documentation. If Windows XP/ 2000, IE 5.0 up and Office 2000 have
WebDAV support, why doesn't MS CMS provide WebDAV support?

Am I missing some important short comings with WebDAV? Apparently not,
because JSR 170 and JSR 147 are both out for public review. Any thoughts/
inputs will be greatly appreciated.

Regards,
Ritu

Latest Slide release

[Ritu Kedia]

I am new to Slide. I wanted to know whether Slide is an ongoing project or
has it been shelved, since a friend of mine told me that Slide project
stopped sometime in 2001. From the Slide home page I am further confused,
since the last news (at http://jakarta.apache.org/slide/news.html ) is
posted on 11/06/2001. Moreover the latest binary download available is of
version 1.0.16. But the changelog page (at
http://jakarta.apache.org/slide/changelog.html) shows the changelog of
version 2.0.0. 
If 2.0.0 is released, why the download page
(http://jakarta.apache.org/site/binindex.cgi) has pointer to Slide version
1.0.16?
Is the searching/indexing module implemented in 2.0.0?

I will really appreciate any replies.

Thanks,
