Yes, and make search hierarchical.
Since you can match inside a match, you can also do this.

To get to match2-3 you need 8 matches

   match1-1  |  1
   match1-2  |  .
   match1-3  |  .
   match1-4  |  .
   match1-5  |  .
   match2-1  |  .
   match2-2  |  .
   match2-3  v  8

But you can do:

   match1  |  1
 match1-1  !  x
 match1-2  !  x
 match1-3  !  x
 match1-4  !  x
 match1-5  !  x
   match2  |  .
 match2-1  |  .
 match2-2  |  .
 match2-3  v  5

And have 5 matches

Cocoon with JBoss-2.4.7_Tomcat-4.0.4

[Niket Anand]

Hello all,
I have successfully integrated Cocoon-2.0 with JBoss-2.4.7_Tomcat-4.0.4 and
it is working fine.
I have properly made ear file containing EJB jar file and cocoon folders as
war file.
If I need to change any XSP and other classes then How will it work without
redeploying all stuffs.
I change an XSP in Catalina_Home/webapps/cocoon folder but not able to see
changes while running server again. If I redeploy all stuff with modified
xsp file then only it show changes.
Please suggest how can I make changes in XSP and classes without making ear
files and redeploying again and again, once it is deployed once.

Thanks,
Niket

Subject: Re: sunRise User Administration for Dummies


I've looked at the user admin and the authentication in general.  (not the
sunrise scratchpad but what's now in the main branch).

As best as I can figure there's a generator that works with the
AuthenticationManager to create an interactive page to get users, a user,
roles, a role, create a user, create a role, update a user, delete a user,
delete a role.  These simply call the various corresponding resources that
you set up with the sitemap.xml (authentication manager section within the
components).  As far as I can tell nothing is really done with them apart
from what you do in the resource.  so the UI really calls the resource that
you configured and you do something with it.  Whatever occurs is not
automagically used within Cocoon's authentication.

Hypersonic appears to only be used for sample applications not for
authentication.  so no users, roles or the association between the two is
stored.  I've found absolutely no JDBC code within the authenication/session
pieces.

My reason for looking into this was from a scalability point of view.  I
like Hypersonic DB for prototyping but not for serious production code.  So
i was trying to make sure this wasn't being used at all for authenication.
The usage of resources allows you to use your own persistence mechanism,
e.g. LDAP, database, XML file, etc.

Also I was looking at the session management.  My gripe is that it uses
HttpSession and didn't make use of calling out to resources as the
authentication manager did.  If the user wanted to use HttpSession or the
database or... let them do that in the called resource.  So ideally there's
a getProperties and a saveProperties resource (oh well).

Also the roles is really confusing, as within the authentication manager
it's not used at all as far as I can tell (it's probably used in the
portal).  There's a roleFilterTransformer that goes off of the J2EE role
that you'd set for the web.xml and use the isUserInRole method.  That's all
the transformer does.  it doesn't actually use the role from the
authentication manager???  so these are unrelated pieces of code.

So the role information that you return from the authenication resource
appears to be left to the developer to make use of somehow, assuming they're
not using Cocoon's portal offering.  I'm fairly certain the portal uses the
role but I've not looked at the portal component at all.

hope that helps.  md

AW: Action example

[Sternath Elmar]

Title: Action example



In the 
cocoon docs there is a nice example how to create AND use 
actions:
http://xml.apache.org/cocoon/userdocs/concepts/actions.html
Inside 
an action, you put key/value pairs into a hashmap which you can then access 
inside the corresponding  tags in your 
pipeline.

Re: Possible with XSPs?

I'm using Cocoon 2.0.3 with Tomcat 4.1.12 on Redhat 7.3.

I put in the default="" and still got the same error, which makes sense because the 
default value is only used if one is not specified in the URL.  Again, here's the URL:

I think that your code is OK.

But i think that you have to put the whole  fragment inside your
root element. I think that in order to use the  tag it
has to be inside your root element.

I Hope that will help.

Escape characters in ESQL

[Katzigas Dimitris]

Hi there,

I want to execute this query over an Oracle database.

alter session set nls_date_format="DD/MM/"

the code fragment from my XSP file is shown below.


  
 alter session set nls_date_format="DD/MM/"
  


This of course doesn't work because i have to escape the double quotes and
maybe the slashes, i don't know.
Even if i use the " instead of the " it doesn't work either.

Does anyone has any ideas on this?

Thank you in advance

Re: Possible with XSPs?

[Sonny Sukumar]

Hi,

I included the xsp-request namespace in my XSP and then put in the code:


 String productId = ;


This code is right above my root document element.  I get this error when I try 
running it by going to http://localhost:8080/cocoon/test?productid=12345678:

org.apache.cocoon.ProcessingException: Language Exception: 
org.apache.cocoon.components.language.LanguageException: Error while instantiating 
org/apache/cocoon/www/products_xsp: java.lang.NullPointerException

The product with productid 12345678 exists in my backend database and the code works 
fine when I hardcode the value into my XSP, rather than trying to get it as a 
parameter.

Any idea what I'm doing wrong?

Thanks again,

Sonny

After reading Stefano's thread on dev (?) regarding
the profiling work he did revealing that matching may
be the most expensive operation, I've been thinking
along these exact lines.  The second one certainly
seems to be the easiest to apply.  Seems like search
algorithm ideas apply here too - you want to get to a
match in the least number of decisions possible, so
either subsitemaps, or nested matchers seem the best
ways to implement a good decision tree.  Seems like
laying out url space can help this.

Question: wouldn't in theory subsitemaps carry more
overhead than nested matchers?  Of course there are
many reasons to use them any way but this would be a
factor in deciding when.

I don't see any benefit (besides different
configurations as mentioned) of multiple pipeline
sections, unless each one has a small number of top
level matchers that can help eliminate all options
quickly.

redeploying all stuffs.
I change an XSP in Catalina_Home/webapps/cocoon folder but not able to see
changes while running server again. If I redeploy all stuff with modified
xsp file then only it show changes.
Please suggest how can I make changes in XSP and classes without making ear
files and redeploying again and again, once it is deployed once.

Thanks,
Niket

Re: [Q] Pipeline best practices

[Markdelanoy]

Another issue of having too  many pipelines.  As i understand in the sitemap is 
generated into a java class.  And the various matchers within a pipeline(s) are really 
a bunch of if-else if statements.  So the more matchers you have (to match to a 
pipeline or various paths within a pipeline) your going to have a large series of 
if/else statements.  And... since this uses string compares and wildcards and... if 
there's alot of these if else if statements it will lead to performance issues.

It may help to break things up with sub site maps to help limit the searching.

Or put the most likely pipelines to get hit first and the least likely last...

XMLForm - VoiceXML

[apurva zaveri]

This is a serious problem about the use of XMLForm in
VoiceXML. While experimenting with XMLForm to generate
VoiceXML this a problem that I faced.

Since in XMLForm all the name of the fields begins
with "/" in HTML 

 is not a problem

while in VXML

 is an error.

What can be done?

You can do it using:

Possible with XSPs?

[Sonny Sukumar]

Hi guys,

Is it possible to access request parameters from within an XSP or logicsheet?

For example, when I go to http://localhost:8080/cocoon/test?param=12345678 I'd like to 
use the value of param in my XSP or logicsheet as a basis for calling Java functions.

In my pipeline, I currently just have the XSP as the generator and 1 XSL stylesheet to 
output to HTML.  I think I could introduce another XSL stylesheet before this one 
which has use-request-paramters set to true and get the param that way, but it seems 
like it'd be slower to do 2 transforms with 2 separate stylesheets rather than 1 
transform with 1 stylesheet.

Thanks!

Sonny

Re: Sitemap question

Let me restate the question.  I noticed that the sitemap isn't 
inheriting things it should be.  I also noticed that in the archives, 
people were running into a problem that was solved by adding a 
hasComponent method to the ExtendedComponentSelector object.

I've been using HEAD for my work (I'm playing with the flowmap among 
other things) and would like folks to know that on my setup, the 
subsitemaps (a) don't take the component definitions from the parent 
sitemap even though it has the appropriate "hasComponent" method and (b) 
the subsitemap will not reload when changed even though check-reload is 
set to "yes", reload-method is set to "synchron".  Reloading will happen 
if I touch the root sitemap however.

Just thought folks should know...

How? check-jars.xml says the following:



and that clearly isn't the case with the sources in CVS. So the build

Some of the reasons are:

 - different error handling
 - different types of pipelines (caching, profiling)
 - internal-only use
 - the use of different expires attribute

Does anybody know some other reasons? As far as I know there is no
difference in performance.

Have a look at the XPathDirectoryGenerator in the scratchpad. With it,
you can generate a directory listing, with a node extracted from each
file. Eg, I used it to extract  elements from a list of Ant
scripts:

The relevant config was:

Could be. If I type:

then it finds ant in the jwsdp/bin directory - that's ant 1.4.1, do I
need a different version?

Actually there is a matching path. Try the demo and type a random string in
a numeric field. The "Ivalid data message" will appear right next to the bad
field.

I think that it makes sense to add the extra logic in the Form class. It
should be relatively lightweight operation.
As you suggestion in the Bugzilla entry, you can use the JXPath API for
this.

I think this is a good idea and I know that other people requested it
before.
It was actually a matter of resources until now.
While working on this, please evaluate the DynaBeans in Struts 1.1 and see
if we can borrow ideas from them.

Need to specify target.vm

[Colin Paul Adams]

Hello, I'm trying to install cocoon 2.1 from a CVS snapshot (Oct
12th). JAVA_HOME points to a 1.4.1 j2sdk (from sun, for Linux). It's
the only version of java I have installed (to my knowledge).

When I tried the instructions for an automatic build, I got an error
that ./lib/core/jvm1.3 was not found.

After investigating, I find adding -Dtarget.vm=1.4 solves that one,
but why is this necessary?

Next problem:

check-jars:
Copying 1 file to /home/colin/xml-cocoon2/build/cocoon
Processing /home/colin/xml-cocoon2/lib/jars.xml to 
/home/colin/xml-cocoon2/build/cocoon/jars.xml

home/colin/xml-cocoon2/tools/src/check-jars.xsl:102:40: Warning! 
  File ant_1_3-optional.jar appears in the lib/ directory, but is not declared in 
lib/jars.xml.

  Please update the lib/jars.xml file to include the ant_1_3-optional.jar file 
together with a description.

Inspection shows that jars.xml is dated Sept 20, and the ant jars to
way back in July. So I don't understand why this error hasn't been
detected before.

P.S. Would this kind of message be more apporpriate im cocoon-dev?

Yes, that's true. 
And it was implemented by Matthieu Sozeau as we discussed. As the
implementation was done long time ago (several months) it needs
synchronization with the current version of Cocoon, but I hadn't time to do
it. Though, if anybody needs the full implementation with updated samples
and dictionary handling, just let me know (kpiroumian at apache dot org).

But note, that this is not an alternative to message bundles, but an
addition. You can still have all the pages generated from a bundle, but
provide some specific messages for a particular language.

So seems that i18n transformer can be cached based on the selected locale
and cache validity of the used dictionary. I have to think about it, but
again I have absolutely no time to work on it, sorry.

Seems reasonable and not only for the i18n:when case.

Thanks for the suggestion Steven. What I have done is to write a perl 
script which I run whenever the xml files are updated. This generates an 
XML file which includes all the others in the directory. So in the end I 
don't use DirectoryGenerator or Aggregation in Cocoon - but CInclude works 
fine.

(I better figure out CachingCInclude too.)

Re: Building a DOM Model with XMLForms

[Robert Ellis Parrott]

I believe that XMLForms are accessed by the pipeline via an Action
Component, based on AbstractXMLFormAction. This is the Component that can
& would handle most of what you are saying below. The Action taken by the
Action will depend on the command encoded in the request; one could, at
the end of many pages, have a submit command that will tell the Action to
validate, serialize, write to DB, email, etc.


The only problem I've found is that the data Model, into which info
entered into the form is written, must already be specified. This is
particularly a problem with the DOM object, since it may not be possible
to specify this ahead of time.


As for DynaBeans (which are now part of the Commons & not Struts, btw ),
it seems that support for them will happen as soon as JXPath has support
for them (which apparently is planned for v1.1). But I've just looked
quickly at DynaBeans; I don't know how easily, with a JXPath that supports
them, it would be to implement a dynamically built DynaBean with XMLForms.
I guess that that would depend on how the createPathAndSetValue() routines
work.

Yes. I thought about this and decided to go with the least harmful message.
For an end user JXPath messagas might be misleading.
Hopefully in future there will be a mechanism for a finer grained
differentiation between problems. Maybe an exception tree of some sort.

I think that exposing JXContext directly makes the XMLForm API unclear... On
the other hand a protected method wouldn't be such a bad idea, at least
until we come up with a better extension to the public API.

A Form subclass (say DynaForm) which creates DOM nodes when not existant
will be a good addition, but we have to document clearly that there is a
danger in using it. If the document author mistypes an element name
reference, it will be created automatically even if it weren't desired. The
current Form class is type safe in this regard.

Re: XMLForm Howto - not Working still

[Ivelin Ivanov]

There is a good chance that your package names or sitemaps are not quite
right.
Instead of typing the howto code,
start with the demo source code which works and change it for your taste.

[Q] Pipeline best practices

[Ivelin Ivanov]

Can someone point me to a document or briefly explain what are the best
practices to writing pipeline in regard of multiplicity.

For example how many pipelines in a sitemap are reasonable?
How do one chooses when to put multiple matchers in one pipeline vs
splitting them in separate pipelines.
What are the performance implications of (not) splitting components in
multiple pipelines?

What happens if you type "which java" ?  Do you get an unexpected one 
installed by your linux distribution?

It looks like you're using an ant that came in some other package.  Perhaps 
that package is missing something.

Why not try using ant 1.5.1 from http://jakarta.apache.org/ant/index.html

Of course, make sure ANT_HOME and the path are set to the right ant.

Re: Need to specify target.vm

Try setting $ANT_HOME and $JDK_HOME as well (and $TOMCAT_HOME if relevant
for that matter)

I built on 10/12/2002 OK, so perhaps just environment?

My only point here is that the message is somewhat misleading. The
response from the Form class is "Invalid data format", while the actual
error from JXPath is actually "Cannot set property /somelement[0], the
target object is null", which is really a different error, not format of
data but the actual path itself. However,  don't think that the JXPath
Exceptions are fine-grained enough so that one can differentiate the two
errors without doing some sort of string matching of the JXPath error
message.

Right. I think the simplest approach would be a getJXContext() method. No
big change. Maybe the same with other private vars?

Well, I'm happy to spend a little time on this, especially if it might
benefit others. I'll look into DynaBeans. Thanx for the pointer.

Re: Building a DOM Model with XMLForms

[Ivelin Ivanov]

Congrats Robert.

I think you're on the right track.

Fortunately, as was the case before, JXPath is powerful enough to do most of
the mapping and creation work for us;)

Please submit a few sitemap examples about your intended result,
so we can iron out any potential issues.


Thanks,

Ivelin

Re: Building a DOM Model with XMLForms

[Scott Schram]

I've just begun looking at XMLForms, and I wonder if this makes any sense:

When the client posts the XForm, we can start with a completely empty DOM 
which is filled in according to the XPath expressions in the XForm.

This DOM starts a pipeline as, say, a PostedXFormGenerator.

Then, there could be a basic validation component in this pipeline, which 
could include validation against a DTD or Schema.  If there's an error in 
this phase, it redisplays the form page with errors.

The user can write custom validation components as well, and they would 
report errors in the same way.

Any Cocoon component could be inserted here..., XSLT transform, Emailing, 
whatever.

There would be at some point in the pipeline would be a component that does 
the business logic with the posted data.  This component would be also be 
able to test for errors and send the form back for client redisplay with 
the errors in a similar fashion to that of the basic validator.

Assuming everything was successful, it could create some output and 
serialize it, or transfer control to another pipeline which would make some 
output.

So, it would be XML pipelines both ways...  no beans at all, unless you 
want to make some using, say, the digester in the Apache commons, or grab 
the data out of the DOM with an XPath -> bean property map.

This might be immensely helpful in systems with hundreds of forms, or where 
the information to be taken in on the form was dynamically generated by the 
business logic, and the fields might not even be known until runtime.  (For 
example, a bugzilla or scarab application that has user configurable forms 
for reporting bugs on different projects.)

It also picks up the advantages of all existing Cocoon components.

What do you think?

I'd be happy to help with this effort, as best I can given 
cocoon-beginner-status.

With respect to DynaBeans in Struts, they're dynamic hash maps of property 
-> value, but you still have to define all of the properties in the struts 
configuration file.  They act like beans, but only if you use the routines 
in the BeanUtils in the commons that were written to support them.

There's a nice summary of DynaBeans here:

Re: Building a DOM Model with XMLForms

[Ivelin Ivanov]

Scott,

Your thoughts are quite logical.
The initial implementation of XMLForm looked very similar to what you
describe.
If you go back in CVS to February-March this year, you will see that
version.

Over time I was convinced by Torsten and Konstantin, that form processing
can involve a lot of business logic and access to multiple resources. This
usually involves non-trivial code which is expected to be secure, high
performing and readable.

Implementing validation with a Transformer and then deciding on the next
step with another transformer is applicable but for the most simple form
handling scenarios. It can easily stretch the limits of a sitemap's
responsibility, which is to organize content, not script business logic.

I suggest that you think of a way to implement the wizard demo with the
approach you suggest. If you can come up with a solution which will be
acceptable to the group, then you can go ahead with the implementation. I'd
be happy to apply the patch.

Otherwise you should partner with Robert, who is already down the path of
extending the currently implemented mechanism to support dynamic creation of
DOM models. See his posts in the last few days.


Thank you,

Ivelin
