RE: A note about the "best(?) (cocoon-) development environment" ...

[Michael Homeijer]

Your classpath issue won't be fixed by other combinations. It's not a tomcat
problem. The only thing that will fix the problem is fixing the java
compiler in Cocoon to not use a classpath, but use the classloader instead.
For this two fixes have been suggested on the mailing list:
- Fixing the piza compiler (I think this was done bij Jakob Dalsgaard)
I tried the fix, but couldn't get it to work in my Cocoon setup.
- Using the eclipse java compiler in Cocoon (suggested by Christopher
Oliver). The compiler he tested should be integrated in Cocoon.

Because I am not working on a cocoon project right now, I cannot spend time
on it. I guess if it bothers someone enough he will fix it?

HTH,
Michael

I use JBoss but not jetty. Are you saying the Jetty-JBoss combo is
superior
to the Tomcat-JBoss combo? If so, I will definitely go try it. Perhaps
it
will fix my classpath in XSP issue. Bugzilla Reference:
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=16580.

Kodo JDO is an implementation of the JDO specification and MORE. It
basically
rules. Go through the tutorials and you will love it. Create an object
model
using your favorite problem domain. Then create the JDO mapping file
(raw XML
or with IDE plug-in) and then just say "uhh, make a schema for me" and
it
just does it. Its amazing! No more screwing around with persistence and
schema manipulation.

I have the commercial version of that product and will be talking about
using
it in the book that I am writing.

Robert:

Have a look at Jetty, or JBoss/Jetty (aka JBossWeb).  No nasty "must
copy things to endorsed directories, etc.)".  You take Cocoon (2.0/2.1)
and drop it in your deploy directory and POOF it's there.  It's nice
when the servlet engine actually uses the libs you define and not its
own first as the default ... isn't that in the spec ... and will be
available in Tomcat at some point.

If you want any extra libs in cocoon-2.1 you add them in the lib tree,
add them to jars.xml and the cocoon build adds them to the Manifest ...
Jetty/Jboss just eats 'em up in the right place.

I'm off to look for Kudo JDO (which hopefully follows the ODMG JDO and
not Sun's) ... how does this rank against Castor or Jakarta-OJB ?

Thor HW

RE: How to open 2 windows?

Hi,

If the "event" you mention is clicking a hyperlink in a html page, maybe you
could use javascript in the the onClick event to open one window and open
the second window with the hyperlink.

RE: Castor Transformer

Hi Harald,

Have a look at: http://nagoya.apache.org/bugzilla/show_bug.cgi?id=12993 
it contains a pretty nasty workaround for the problem and works with
castor-0.9.4. If you find a better solution please let us know.

Right now I am working on a new version of the transformer that can use

Subject: Castor Transformer

I am using a Cocoon-Developer-Snapshot from October this year.
The Castor Transformer i fetched from CVS. Unfortunately this class uses

a lot of deprecated stuff. Additionally i have to serialize a 
java-object stored in my xmlform.

So i tried to write my own transformer.  The code is attached here. The 
Castor Marshaller needs a Sax-ContentHandler that I get by calling the 
variable "contentHandler", available in the transformer.

Following Exception do I get. Do I have to set the Sax-Parser in the 
Properties? When I set the Sax-Parser from cocoon.xconf additionally in 
the properties i get a ClassNotFoundException.

When i replace the deprecated Classes from the CVS-transformer same 
things happen.

Any help is appreciated.

RE: 1001 question aboit Command Line Interface

Besides setting the path in different lines, like Bertrand explained,
additionally you can use the subst command to shorten the path spec to your
libs, something like: subst x: "path to\WEB-INF\lib".

RE: Cocoon and EJB

[Michael Homeijer]

I think you have some options in Cocoon:

- Use the castortransformer to transform the resulting data from a bean to
XML. (and then process it additionally with XSL).
- Use the velocity generator to get data from a value-object result from an
EJB.
- Write a jxpath transformer (is probably allready available as part of the
xmlforms solution) to get data from a value-object in xml.

In all solutions you probably have to get the result from an EJB in an
action class and put it in the request object. Other possibilities would be
to output your bean data in XSP, that would probably mean writing a lot of
code, or to adapt the xmlforms solution to use EJB's.

There aren't many mistakes you can make in things like sitemap or your xml

RE: Install error win2000 IBM jdk 1.3.0 Websphere 4.0.2 Cocoon 2.0.2

[Michael Homeijer]

Hi,

I am experiencing the same problem under websphere 4.0.4 with the latest
version of Cocoon. The code that mentions the webshere bug is still in CVS.

When I remove the workaround code for the websphere bug, it's working, so it
seems the bug is solved in Websphere 4.0.4. Now removing the code will
create problems in Websphere 4.0 / 4.0.1 (and maybe not solve them in
4.0.2), is this a problem?

TIA,
Michael

Manifest problem, deploying Ear (Cocoon + EJB's) on JBoss / Jetty

[Michael Homeijer]

Hi,

I am trying to deploy an ear containing a Cocoon web-app on JBoss / Jetty.
The problem is that when I have an ejb-client.jar in the web-inf\lib
directory, jboss gives a classcastexception on the
PortableRemoteObject.narrow call (probably because the home interface is in
the VM twice in two different classloaders?). Anyway...

According to Jboss, the way to deal with this is to have the ejb-client jar
in the EAR file itself and reference it from the meta-inf\manifest file in
the Cocoon application.

My problem is that referencing a jar from the manifest file doesn't seem to
work. In an XSP page, the class from the ejb-client jar cannot be found.
Does anyone have this setup working? Any workarounds?

TIA,
Michael

Hi,

You probably mean a Reader. A Generator generates a SAX stream and a Reader
produces a binary stream.
Have a look at org.apache.cocoon.reading.ResourceReader.

RE: Cocoon Portal - Tabbed layout and Radio integration

[Michael Homeijer]

IMHO the problem with most portal layout's is that if you have multiple
"portlets" open and one is changed, the complete page has to be refreshed.
Depending on the functionality and the possibility of caching, this can be
very time consuming.

Gartner had a site that solved this by having portlets in a single "layer"
(I am not a HTML expert, but I think this is what it's called). It looked
great, all portlets could be dragged to the location at which you want to
have them and they really looked like child windows.

Did you ever look at a layout like this to use in Cocoon? (I am sorry I
cannot find a link with a sample, it was one of the customizable gartner
sites you have to login to. Maybe some one knows what I mean).

Michael.

RE: writing xml to file - Solution

[Michael Homeijer]

Please note, the XMLDBTransformer does the same (it stores data in the
XML:DB database, but that's the only difference).
This way you can process the output of the transformer (XMLDBTransformers
outputs a tag with success/failure and a generated key) by another
transformer to transform it to HTML. With the serializer approach this is
not possible.

If you want to write a FileWriterTransformer or something you can get ideas
from the XMLDBTransformer.

Michael.

[slightly OT] I really need ideas about a CMS to use with Cocoon

[Michael Homeijer]

Hi,

I am working on a project that planned to use the java CMS from arsdigita
(www.arsdigita.com). 

We noticed a news item about arsdigita that keeps us from using the product
in our project
(http://slashdot.org/article.pl?sid=02/02/08/1319206&mode=thread). We were
in the stage of evaluating how it cooperates with Cocoon 2.

Right now I could use some ideas on CMS's that integrate well with Cocoon,
are built of reusable components and provide at least some rudimentary
workflow mechanisms.
Furthermore the CMS should be able to work on a foreign database (ie. not
their own metamodel or something).

Any ideas?

TIA,
Michael Homeijer

RE: xmldb logicsheet (XMLDBTransformer is a great start)

[Michael Homeijer]

Have a look at the XMLDBtransformer in scratchpad, it could be easier to add
your functionality there.

Additional functionality for the XMLDBTransformer could be:
- resolving nested xml queries and/or structures (ie. get the collection and
then get a document)
- adding stuff dbxml provides at the command line, ie. listing, adding,
removing and querying collections

To do this two changes have to be made to the transformer:
1. implementing it in a way that commands can easily be added to it. (How
about innerclasses that handle a command?)
2. you should be able to use results from a query or a command in the next
query.

Getting dbxml to work with Cocoon and tomcat 4

[Michael Homeijer]

Hi,

Can anybody give me some hints on how to get dbxml to work with cocoon and
tomcat 4. I tried placing jars in just about any location that could make
sense, but I can't get it working completely.
(OpenOrb is the initial problem, it cannot find its properties in the jar in
web-inf/lib).

TIA,
Michael Homeijer

Incoming pipeline?

[Michael Homeijer]

Hi,

For a prototype I have the need to store form data in a Xindice (db:xml)
database. I was thinking of writing an action that generates xml data based
on the request, calls a transformer and then stores the xml data in
Xindice).

Right now I am trying to find code that will be helpfull with this
(copy/past reuse). This got me thinking, how hard would it be to use a
normal pipeline to generate my data and instead of a serializer write some
kind of component that stores my data at the right destination in the xml
database:







Maybe somebody can give me some comment on the approach or give me some
hints.

TIA,
Michael Homeijer

Cocoon and CMS

[Michael Homeijer]

Hi,

In the past I have experimented with some opensource CMS systems like the
ones from mmbase.org and opencms.org. 
As far as I can see the opencms.org cms cannot be used without the front-end
they provide and integration with cocoon will be hard.
The mmbase.org cms could be used with cocoon for content publishing (right
now they only provide a jsp tag library but I suppose this could be turned
into a logic sheet).
Only it doesn't store XML.

Did anybody find a XML based cms that seperates content management from
content publishing and could be used with cocoon for publishing?

(Now that Xindice is an apache project, maybe a cms using xindice, cocoon
and maybe other stuff would be a great showcase?)

TIA,

Michael

RE: cocoon2 performance

[Michael Homeijer]

Hi,

If you add a timing for pure XSP (without XSLT), you will know where to tune
(XSP or XSLT). Maybe you can report this back also.

In the original mail in the following URL there's something you can try:
 http://www2.real-time.com/pipermail/cocoon-devel/2001-August/010394.html

(try to get the generated source code of one of your XSP, compile it
as a generator and use it as a normal generator instead. [this should
remove the XSP loading/handling phase])

Let us know the result.

HTH,
Michael Homeijer

DeltaTimeCacheValidity

[Michael Homeijer]

Hi,

I needed a cachevalidity object that keeps the result of an XSP page in
cache for a specified amount of time.
For this purpose I wrote DeltaTimeCacheValidity.java

The constructor argument of the object is a delta time in seconds. The
object is kept valid in cache for the specified amount of time.

Can anybody comment on this approach?

TIA,

Hi all ..
.. sorry .. today I'm flooding this mailing list :))

I would like to know if there is a way to make something if a given
file 
exists.

Actually i'm doing a lot of content aggregations, and i'm searching
a way 
to aggregate a document only if the given document is there. I've tried to 
put it on a different pipe, then aggregate it with 
"cocoon:/thepipe/etc../etc..", but if the generator of the subpipe doesn't 
find the document it drops both the subpipe and the aggregation.

Thanks, and ciao ..

RE: Cocoon and J2EE (How about setting up EJB support in Cocoon?)

[Michael Homeijer]

After a quick look at the files, I have to following question about your
solution:

Why did you choose not to write a logic sheet? One of the benefits of a
logic sheet
would be that you can add your own code in xsp in addition to the code that
will
be generated to call the EJB.


Other comment on Cocoon and J2ee:
One of the things that we did to interact with bean was to standardize
result sets
that were returned by beans. These result are transformed by an object that
implements
xmlfragment and while the resultset is transformed to XML, additional custom
processing
can be done by writing custom classes (eg. whe have an inner class that can
URLEncode attributes).

The code we write is now as easy as (in an xsp page):

InitialContext ic = new InitialContext();
WebPollXMLHome eh = (WebPollXMLHome)ic.lookup("WebPollXML");
WebPollXMLRemote er = eh.create();

Collection poll = er.getCurrentPoll();

new
XMLObject(poll)

A logic sheet could even simplify this a bit more.

For the bean side, we generate so called DataAccessObject's (See j2ee
pattern catalog from sun) based on
sql in a xml component definition file.

I have thought about how something like this would fit into Cocoon (even
some sort of xsp language for EJBs,
but lets stay on the ground for now ;-)) but the approach we now have uses a
proprietary ejb result format we defined ourselves.
(Maybe this could be handled by some construction  in the xsp
logic sheet uses).

If anybody is interested in integrating EJB support in Cocoon, i'd be
willing to help.

Any ideas on how to set this up? Do we need some kind of voting on the
mechanism used? Other ideas?

TIA,
Michael

Roll-out of www.mysuncatalogue.com

[Michael Homeijer]

Hi,

I am proud to announce a new site build with Cocoon 1.

In the coming months, www.mysuncatalogue.com will be rolled out in 55
countries in 13 languages.
(Meaning it will replace www.suncatalogue.com and links to the site will be
available from the various Sun sites, additional servers and
clustering/load-balancing will be implemented, possibly additional
performance and tuning and maybe a migration to C2 will take place).

The site is running on: Sun Solaris (of course), Oracle 8, Borland
Application Server, iPlanet Web Server. 

It's a dynamic site built with Cocoon 1 techniques (mainly xsp and xsl) in
combination with Enterprise Java Beans. 
Because of the multi-language and personalisation aspects of the site, all
data (including menu's, labels etc.) is retrieved from the database.

Based on the experience we have with Cocoon 1, we are now building a
framework and development procedures in which Cocoon 2 plays
a big part. 

Thnxs,

Michael Homeijer

Internal redirects

I am working an a mechanism to have annotated pages in my web portal (like
the pages in the pet store).

The pipeline to get this working looks like this:

   

 
 



   

This way, when i have a page, say "portal", cocoon loads the portal page and
it loads the annotation page. 
The problem I have that all my images in my portal page, now refer to
annotated/image.gif instead of image.gif.

For normal images until now I duplicated the pipeline, but I also have
generated images (svg2jpeg).
And i'd like to have an internal redirect for this, something like:

   

   

Is this possible?

To my understanding, pipelines without serializers could be used in an

Should I define internal pipelines in another way or was I on the right way?

RE: [C2] SOAP - Scanned for virus

[Michael Homeijer]

Hi,

If you mean the stuff I sent to the mailing list: it ended up in the cvs bij
mistake.
They were just meant as an example to show what could be done with soap.

In my opinion, an implementation of soap in C2 should not just be a
logicsheet,
but an extra channel in the interface with cocoon (both serving soap
requests and performing soap requests on
other servers). This way it should be easier to implement xml based services
in a cocoon application instead of only xml based publishing.

I think Giacomo has some great ideas on the subject. You can also check my
previous posts on the subject.

Michael Homeijer

I'm not sure.  Cocoon 2.1 is simply the same as Cocoon 2.0
with some extra stuff.  Try just pulling 2.1 from CVS, and
extract what you need.

RE: Cocoon and threads

[Michael Homeijer]

 Hi,

Could you put the code in your mail where you retrieve the session object
itself?

Pages aren't synchronized because this introduces a bottleneck,
and because they don't need to be. Just be carefull with your variable
declarations.
