Re: Error : 500 Internal Servlet Error

[Brian Blakeley]

As I understand it Java does not allow methods larger than 65535 bytes and
therefore you need to break up things a bit.

Re: PDF Table Template?

[Perry Molendijk]

This is not a Cocoon error it's a fundamental XSLT error. Constructs like:





are bad.

If you want to use a named template for a table do this









or

use an  so you can set all the attributes for your tables
in the one spot.
200px








BTW this is probably off topic for this list. Use

Don't remember action sources... It just might be they do not use
resolver to get descriptor.

Any (sub) protocol can be used throughout the system if using resolver.

PS: Grab CVS version of sitemap.xsl - it has the bug fixed.

There has been a bug in a class which generates a loop under Tomcat 4.x.
It is fixed in the Cocoon CVS. The class in question can be found here:

RE: [Action] Best practices for authentication

[Pascal Davoust]

Mmh, I probably missed something here... I tried what you proposed, but I
get a compilation error. Here's what I did at first, which works correctly:


  


  
  

  

  


(login is in another pipeline... does it matter?)

And then I tried to reverse the pattern, like this:


  
  




  

  


And I get an error, which is :
Error compiling sitemap_xmap: Line 901, column 6: Undefined variable: param

I had a look to the source code, it's obviously missing the variable
declaration. Did I forget something here?

By the way, I found that the "context://..." specifier as a parameter value
for the action descriptor doesn't work (did I correctly understand that this
sub-protocol is related to the sitemap?), whereas "file://" does the
trick (I want to specify a path relative to the sitemap its written into).

Thanks,

Pascal.

PDF Table Template?

[Ryan Howe]

Hello,

I am attempting to use the stylesheet included below
to transform an XML file to PDF using Cocoon 2.0.1. My
hope to build multiple tables in the PDF file. I have
created two templates in the stylesheet for opening
and closing a table. 

When running this through Cocoon, I get a
NullPointerException in Xalan
(TransformerImpl.run(TransformerImpl.java:3174)). If I
uncomment the  tags in the stylesheet
comment the call to the two templates, it runs fine
through Cocoon. 

Since I will create about 6 tables in this file, I
would like to have a template to open the table and
setup the columns instead of coding the same thing
several times. 

Would anyone have any ideas how to get around this?

Error handling design question

[Alexander Smirnoff]

After playing with cocoon for few month I found that it quite
strong and bold to be used in production environment. But
there are some weak points which I've noticed.

One of those is abnormal situation handling in XSP files. So
far I've tried few approaches.

The requirement is :

In the case of error present XML message containing the 
error number and the reason of error occurred.

First straight-forward approach was to use
request.sendRedirect(messagepage) method. But this in
some cases will result in IllegalStateException.

Second (which we are using in our application) is embedded
message approach. In the case of error message is 
embedded in XSP and later in the pipeline is filtered from
excessive tags. The only drawback of this approach is that
in some cases the execution of XSP must be terminated
with "return" statement or throwing an exception, which 
means all open SAX events must be consistently 
closed. Using  will cause 
additional CPU load.

Maybe there are better solutions?

I'll appreciate to get some new opinion about this issue.

Thanks,

RE: Cocoon, XForms, ExFormula, Chiba, Struts, etc

[Ivanov, Ivelin]

That sounds good.

We've used Castor for successfully binding heavy XML traffic. 
Have you coordinated efforts with the folks that started ExFormula. 
I see that Chris is still active on the Cocoon list.

The reason why I am opening this subject again is 
because I think it can add significant value to Cocoon.
I am prepared to put some time working on this.

Please let me know if we should keep this discussion in the dev mailing
list.

So, as briefly as I can, I'll share my experience and ideas:

For those who haven't used Struts:
It is a succesful Apache project (http://jakarta.apache.org/struts) which
automates the task of mapping html forms to value objects used in an
application domain.
It's expected to influence directly the following JSRs:
JavaServer Faces JSR: http://jcp.org/jsr/detail/127.jsp
JSP 1.4 JSR: http://jcp.org/jsr/detail/152.jsp

If it's so good, why are you posting on this list ?

Struts is great with HTML forms. However it doesn't deal nor it plans
to deal with any other sort of media.

It doesn't take into perspective web services for example.
We want to reuse the interface layer for SOAP clients as well.
For some time now our project had pending requirements for web services
support.
We want to let other companies integrate with our portal. 
A reason why we keep pushing this requirement off
is that it can't happen easy. All our external interface have been tied to
JSP+Struts. Since we want to allow customers to do through web services 
what they could do through the regular Web UI, we'll need to write a brand
new 
interface layer. We won't be able to reuse the automatic population and
validation
that we have for the HTML interface.

Being a Cocoon newbie, I might be totally wrong, but
it appears that the current Cocoon architecture is
also focused towards HTML form validation (through
rules for HTTP POST/GET params), but it also does not
try to deal with other media like SOAP.

Last October there has been an interesting discussion
on the Cocoon mailing list about integrating server
side XForms. 
I found it quite interesting, because based on my
experience I do believe there is a farely good chance
that XForms (or some limited version) can be
successfully integrated in Cocoon so that data
validation and java binding code (two way: web client
<-> XML <-> Java domain objects) can be easily reused
for clients ranging from HTML to SOAP. I also believe
that this can be achieved with a sufficiently high
performance (in many cases the WebClient <->
JavaObjects transformation can be achieved without
necessarily going through naive XML representation. 
Instead using SAX events and JAXB ).

Additionally data validation can be probably achieved elegantly
through parser (xerces2) validation against XML Schema.

Berin, Chris, Torsten and others seem to have made similar observation 
and have therefore started ExFormula last year. 
Chiba looks promising too. 


Can we try to unify and finish the job started, so that Cocoon moves to the
next level.


I'm all ears !

Hi
we are working on a integeration from

we like to use castor to perform

Beside this we wrote some basic

I hope that you will see a basic

Hi,

After using successfully JSPs+Struts for a relatively big enterprise
project, I've grown to appreciate the MVC model, but have also found some
places where it can be improved.

Before starting a long discussion, I'm first just looking for a short answer
to the following question:

Does Cocoon 2 have a mechanism for achieving automatic Form population and
validation, similar to Struts ?

I've noticed that in the project archive XForms and ExFormula have been
discussed on a number of ocasions, but they've been integrated in C2. Am I
wrong?

I will appreciate a prompt response.

Thank you.

Re: Cocoon1 -> Cocoon2

[Joseph Jupin]

In our design, we were trying to keep a clear delineation 
(sp?) from our transforming engine (cocoon) and our 
requestor - in the case of the code I provided, this was 
to show how a servlet from another web server could call 
cocoon and get the transformed results - we also have a 
swing client that calls the cocoon server to help 
dynamically generate our user interfaces (cocoon generates 
our version of XUL)...  you get idea...

We never meant for everything to be contained within one 
sole process/webserver...  just my $0.02 (US)

Stick with Tomcat 4.0.1 which is known to work with cocoon, watch on
this list for info when issue with tomcat 4.0.2 is resolved.

[Joseph Rajkumar]

Hi
This problem has been posted by me and many
others on this mailing list. Depends on what you wish to
do.
If you want to get TC+Cocoon to work, go to
version TC-4.0.1 and Cocoon-2.0.1 with everything else
as you have it. Then you will be fine.

Installing Cocoon 2.0.1 on Tomcat-Standalone 4.0.2 with JDK1.3.1_02 and Windows 2K Pro

[Barnaby Shearer]

I have just downloaded a binary distribution of Cocoon 2.0.1 and cannot get
it to run.

I have am running Windows 2000 professional with Sun's JDK 1.3.1_02 and
Jakarta-tomcat-4.0.2 in standalone mode. These all appear to be working
correctly.

I have copied the cocoon.war file into tomcat's directory and restarted
tomcat. This successfully unpacked the .war file and created the cocoon
directory.

When I try and access cocoon (via http://localhost:8080/cocoon/) I get the
following message:

[Action] Best practices for authentication

[Pascal Davoust]

Hi all,

I've been experimenting with Cocoon 2.0.1 (and before that with Cocoon 1,
but didn't do much with it because of the lack of features more than
available in C2 now, mainly actions).
And now I'm wondering about the 'protected' sample in the distro.

Basically, having a page protected by authentication involves an action
(DatabaseAuthenitcatorAction, in this case) to check that authentication was
successful before serving the resource (understand: page), or redirect to
login if authentication failed.
The pattern for this is basically:

  

  

  

And if I correctly understand, it means that I've got to specify that schema
for *every* match I want to protect, right? Seems a bit of overhead to me
(may increase the maintenance cost for the sitemap)...

Is there a "smarter" way of doing this? Quite frankly, that's the only one I
see (I came to that conclusion myself *before* seing the protected
sample)... but you guys have zillion times more experience than me with this
topic! :)

By the way, C2 rocks! :)

Thanks,

Pascal.

Can you pinpoint the reason of slowdown? I'm not sure that there are
significant changes in the XSP machinery between these two versions.

Re: New release 2.0.1 woes. Continue.

[Alexander Smirnoff]

OK. I've got it. Thanks.

I understand the motivation to exlude autocomplete is 
to speed up the pipeline process. So XSP developer
must be responsible of consistent closing of his elements
if he or she wants to return somewhere from the middle of
XSP logic.

General note: it seems 2.0.1 compared with 2rc1 is 
significally slower for more or less complicated XSP.

RE: problem with blank java files for xsp/serverpages

[David Stenglein]

Thanks a million!!  Should have asked earlier, but I wanted to research
it enough first.  

The thing that confused me terribly is that the test.xsp in the webroot
wasn't actually the same!! Somewhere, I made one with the correct
namespace reference, but never thought they were different. Oh, well.

I really appreciate the speedy response, because I'm pushing cocoon for
new development and it always helps to say that help can be as little as
15 minutes away.

servlet, generator or ... (design question)

[Mike Haarman]

We are evaluating C2 for a very large, public, data-dissemination project
(NHGIS.ORG).  I would like to build a few small XML visualization tools in
C2 for demonstration purposes.  For example, a facility to upload an XML
instance, associate it with a stylesheet living on the server and return
transformed XHTML.  The upload need not be saved anywhere on the server;
I'd like to hand the uploading stream directly to Cocoon.  I can clearly
see a couple ways to accomplish this but suspect there are more:

a) Specify a servlet external to Cocoon which handles multi-part form data
as the src attr on my generator in the pipeline.  How does this kick
off the pipeline's processing?  I suspect I need to bind the upload stream
to the pipeline within my servlet and make a call to Cocoon but I'm not
clear how.  Or is Cocoon waiting like a daemon for bytes to show up at the
mouth of the pipe?

b) Extend one of Cocoon's generator classes (StreamGenerator?) to handle
the multi-part form data and call it from my form.

c) Is there a way to modify the File Upload example to hand the upcoming
stream to a transformation?  It seems that example merely specifies a
directory for uploads and does nothing with the stream itself.

d) ?

What is the cleanest manner of doing this?  I suspect there is a Cocoon
pattern lurking in this problem and would like to implement the solution
that best reflects such a pattern.

RE: calling a HTML-file from an XSL-file

what

Maybe 
you setup Tomcat (or wathever servlet container you're using) to process only

ANNOUNCE: jfor/Cocoon HOWTO - generating RTF with Cocoon

[Bertrand Delacretaz]

To all RTF fans: hot off the virtual presses, a new technote 

"jfor/Cocoon 2 HOWTO: dynamic generation of RTF documents from XML with 
Cocoon 2 and jfor"

Is now available at http://www.jfor.org/jfor-cocoon-howto.html

It explains how to activate the RTFSerializer that is part of the 
Cocoon 2 source tree, but not activated in the standard Cocoon 
distribution.

As always, feedback is most welcome (even if it works ;-)

This issue is fixed in the Cocoon CVS. Error message returned now looks
like:

"This page is not valid page of this markup langugage. Root element is:

Which means that your page's root element is

Return is prohibited in the main method of the XSP. Use it in own
methods if you want, but with care. And even if you use it in the main
XSP method (despite the fact that it is not recommended), XSP engine can
cover your mistakes if you set autocomplete-documents to true. Of course
this feature isn't for free, performance of you system will degrade.

because the jave file is nearly empty (4 newlines). I've been testing
lots of different combinations of tomcat (3.2.3, 4.0) java (1.3.0,

specifically seems to be hapening when I mount a subsitemap.

I have attached a zip file with a sub directory containing the sitemap
and the xsp. I added the following to a stock 2.0.1 sitemap:









When I request break/test it does the NoClassDefFound and leaves the
.java with 4 newlines in the work directory.  If you copy the sitemap
entries and the xsp to the top level, it seems to work fine.

What is this??

RE: More on Cocoon 2 generated SAX Exception

[SANSONE, AARON M [Non-Pharmacia/1000]]

More info:

RE: SAX to DOM Pipeline with an AbstractDOMTransformer

In an attempt to determine what was causing this exception, I dug into the
code and started to low-tech debug (aka System.out.println).  I found
something interesting.  The content handler is NULL when trying to process
the SAX Events through the AbstractDOMTransformer.  I added a series of
printlns in the AbstractXMLPipe on start and end document and the start and
end element methods.  In each case the contentHandler is NULL.  

Hopefully this will help in debugging.

RE: UnnamedSelector: ComponentSelector could not find the component on custom Action

[Lewis, Andrew J]

ok...I was right - it was something stupid.

I was inheriting from ConfigurableComposerAction but then masking the
ComponenetManager variable in my class, and not providing an implementation
of compose() to correspond. Looking up componenets off of a null
ComponenetManager doesn't appear to work very well.

That said, Things like NullPointer exceptions thrown during configure() ever
make it to the stack trace in the result, which made finding this a bit
harder, and even made it look a bit like my Action was not even being found.

Shortly: it wasn't about aggregation, nor my new sitemap structure. It all
happened, cos I switched from C2.0 to Cocoon 2.0.1 meanwhile, and it has
really expansive logging, switched on by default.. I've turned it off, and
average page processing time dropped from 1200ms (even 2200 on some pages!)
to 200-300.

Sorry, my fault - seems I've missed the release note about that :)

Re: New release 2.0.1 woes. Continue.

[Alexander Smirnoff]

Sorry for misleading about the "global" method, - it works fine.

The problem actually is different:

If I put "return" between open and close tags it results in empty document. 
Look at example:

http://apache.org/xsp";>


if(true)
return;




Quite important feature I would say.

Cocoon + Lucene + Xindice

[Yaser Al Masri]

Hi,

I've been looking to the implementation of Lucene inside Cocoon, and it's 
great what this combo is able to deliver.  Things will continue to work 
perfectly until database shows.  The 'like' and 'contains' functions in SQL 
and XPATH queries respectively cannot make much use of the indexing supplied 
by the corresponding database because they're a sub-string search, while 
search engines will help here because of the implementation of full-text 
string searches, so I guess the justification for using search engines 
rather than query statements for this case is valid.

The problem here ASAIK is that to use lucene you have to supply it with 
Directory object that points to the location of your data files, which 
doesn't exist here in case of database. I thought I could mimic the 
implementation of Lucene inside cocoon but for the Xindice database instead 
of the spreading files, so I started studying the crawler behavior and if it 
could be attained with the help of the pseudo protocol implementation for 
Xindice, but I stuck there with the fact that I'm only mapping URLs to 
underlying database not to actual directories and files seen to the indexer.

On more problem appeared to be there is the information retrieved from the 
searcher.  For many cases that native XML databases help in, it would be of 
no use to the use to get a URL for his search rather that a brief 
description to the document he searched (like in searching for items in 
catalog where the description and the image matters more than the URL that 
links to it).  So I thought if Lucene could be adapted to retrieve documents 
inside collections rather than URL.

Can anybody give me an insight on this issue? Are there any future plans to 
include search support for XML and other databases?  How do you think the 
support of XQuery language will help in the search process?

Thanks.

Way to go. Yes, StreamGenerator.

It has different purpose; it supposed usage is to upload binary
resources, not the XML which requires further processing.

Nope. Use matchers/selectors/actions to get them and pass to the

servlet, generator or ... (design question)

[Mike Haarman]

We are evaluating C2 for a very large, public, data-dissemination project
(NHGIS.ORG).  I would like to build a few small XML visualization tools in
C2 for demonstration purposes.  For example, a facility to upload an XML
instance, associate it with a stylesheet living on the server and return
transformed XHTML.  The upload need not be saved anywhere on the server;
I'd like to hand the uploading stream directly to Cocoon.  I can clearly
see a couple ways to accomplish this but suspect there are more:

a) Specify a servlet external to Cocoon which handles multi-part form data
as the src attr on my generator in the pipeline.  How does this kick
off the pipeline's processing?  I suspect I need to bind the upload stream
to the pipeline within my servlet and make a call to Cocoon but I'm not
clear how.  Or is Cocoon waiting like a daemon for bytes to show up at the
mouth of the pipe?

b) Extend one of Cocoon's generator classes (StreamGenerator?) to handle
the multi-part form data and call it from my form.

c) Is there a way to modify the File Upload example to hand the upcoming
stream to a transformation?  It seems that example merely specifies a
directory for uploads and does nothing with the stream itself.

d) ?

What is the cleanest manner of doing this?  I suspect there is a Cocoon
pattern lurking in this problem and would like to implement the solution
that best reflects such a pattern.

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

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,

 adds attributes to tags that create SAX events,

Setting attributes of the esql tags dynamically

[hugo burm]

How can I set the "column" attribute of the tags in the esql taglib
dynamically? xsp:attribute generates an error.

The problem:
I have simple sql query "select * from mytable".
Mytable has 5 columns.
The code below generates a Xalan transformer error in C2.0.1  (W2000, Tomcat
4.0.1):
When I replace the outdented code below the  line with:
ic the numbers 12345 are printed as expected.
(cnt=number of columns=5).
When I replace the outdented code below the  line with:
 , the name of the first column is printed
5 times as expected.
So the logic and the query are ok, it is the xsp:attribute that generates
the error.

At the end of the esql documentation of the esql tags there is a note in
documentation of "@*|node()" that the taglib expects a  tag
with the name of the column as content when there is no column attribute
(after evaluating xsp which is what I need). I experimented with this but
that didn't work either. How can I use this?

Thanks

Not (exactly) true - depends how you implement it. Read on Avalon or

Well the answer is to put the URL of your servlet in the sitemap :



 http://localhost:8080/alexcocoon/AlexServlet"; 
/>  
 
 



Good luck Geza

How can I do that ? Should I implement the Generator interface too
in my servlet, or do the HTTP request thing what Jupin suggested ? 
Or is there any other way to do that ? I saw plenty of exapmles 
which use JSP, HTML, XSP and other thing as a generator, but nowhere
a simple Java (servlet) code.

RE: Cocoon1 -> Cocoon2

[Alexandre Victoor]

You are welcome :)
But you have to look at the memory aspect too...
A new instance of the generator is created at each request and so the 
amount of memory allocated keeps increasing.
With cocoon2 you can also use a servlet as a generator. It's certainly not 
the best solution neither but since you have already a servlet...
Good luck

Thanx Alex. I guess this was exactly what I needed.
I assume that from the performace point of view this
is not the best solution, but I right now I already have a huge
amount of code in a servlet. In order to make the pages
configurable, I ported the whole thing pretty easily
to Cocoon1. I converted my servlet into a Producer.
Now I'm trying to do the same thing for
Cocoon2. If I could, I would start the whole thing all

RE: MySQL Insert

[SANSONE, AARON M [Non-Pharmacia/1000]]

Ferran,

Yes you can do any SQL statement using the transformer.  An insert may look
like this:



http://apache.org/cocoon/SQL/2.0";>
  http://apache.org/cocoon/SQL/2.0";>
   
  insert into tablex ( username, password, activeFlag ) values
('', '', 'Y')
   
  



Then process this throught the SQLTransformer and you should see your data
in the DB (assuming you have access to insert to this table of course!).

HTH,
Aaron

Hi
we are working on a integeration from

we like to use castor to perform

Betreff: Cocoon, XForms, ExFormula,, Struts, etc



Hi,

After using successfully JSPs+Struts for a relatively big enterprise
project, I've grown to appreciate the MVC model, but have also found some
places where it can be improved.

Before starting a long discussion, I'm first just looking for a short answer
to the following question:

Does Cocoon 2 have a mechanism for achieving automatic Form population and
validation, similar to Struts ?

I've noticed that in the project archive XForms and ExFormula have been
discussed on a number of ocasions, but they've been integrated in C2. Am I
wrong?

I will appreciate a prompt response.

Thank you.

Here is a dummy generator that parses a string and gives the sax events to 
cocoon. Hope that is what you need.
 From my experience I can tell that it is not the best thing to do with

Implement a generator or write an XSP page.

Not a string...

... but a SAX events. If you really want to have an advantage of
skipping XML parsing, you should generate SAX events.

If you don't have knowledge of how to do this, take a look at Java code
generated out of XSP page.

Cocoon1 -> Cocoon2

[Geza.Szocs]

Hi guys,

 I've had a simple java code which produced XML
output. In Cocoon1, I had to implement some Producer
interface, so my java code became integrated in the
Cocoon servlet. Does anybody know how to do similar
thing in Cocoon2 ? I've read the code snippet written
by Jupin, but I have something else in my mind. I don't
want to send an other HTTP request to Cocoon, I want to
write string XML directly into the pipeline. I guess
I would have to implement some kind of a generator. 
  Can somebody help me ? I want to port my cocoon1 
implementation to cocoon2. Thanx.

mod_webapp info needed

[Bert Van Kets]

Can anybody tell me where I can ask questions regarding mod_webapp?  I 
installed Tomcat 4.0.1 and Apache 1.3.20 on SuSE 7.3.  I'd like to direct 
the root of my Apache site to a Cocoon webapp.  It runs fine in Win2K, but 
Apache can't seem to talk to Tomcat in SuSE Linux.  I'm getting file not 
found errors in the browser, but no errors in the log files.
I'm using mod_webapp 1.0.1-tc401.
Thanks,
Bert

Are you using tomcat 4.0.2 rpms or tgz ?

I copied the PJA jar files to the jre/lib/ext
directory and added the following line to the catalina.sh file

CATALINA_OPTS='-Xbootclasspath/p:/usr/local/pja/lib/pja.jar
-Dawt.toolkit=com.eteks.awt.PJAToolkit -Djava2d.font.usePlatformFont=false
-Djava.awt.graphicsenv=com.eteks.java2d.PJAGraphicsEnvironment
-Djava.awt.fonts=/usr/local/jdk1.3.1_02/jre/lib/fonts
-Duser.home=/usr/local/pja -cp /usr/local/jdk1.3.1_02/jre/lib/ext/pjatools.jar'

works fine on a headless SuSE 7.3 machine.  You might have
to change the paths a little.

Apologies in advance for the long windedness of this
post, I wanted to
get all the details down.

I'm trying to install cocoon on a tomcat server on a solaris box
cocoon=2.0.1
tomcat=4.0.1
solaris=2.8
jdk=1.3 (in j2se)

I have been successful in deploying cocoon in tomcat on windows xp as a
test, but I need it on my solaris box to do actual work on.

I tried straight deployment off dropping the .war into webapps and going
to the cocoon url but got the sitemap errors in the page. 
After reading the cocoon install guide and cocoons error.log I realized
I was operating in a headless environment.

So I downloaded the pja jars and installed them in /usr/j2se/jre/lib/.

I have put the pja jars in the classpath tomcat uses by altering
bin/catalina.sh, so the classpath setting line now reads:

CP=$CP:"$JAVA_HOME/lib/tools.jar":"$JAVA_HOME/jre/lib/pja.jar":"$JAVA_HO
ME/jre/lib/pjatools.jar"


($JAVA_HOME=/usr/j2se)

I added suitable CATALINA_OPTS to bin/startup.sh and bin/shutdown.sh as
suggested on the cocoon site 


CATALINA_OPTS='
-Djava.awt.graphicsenv=com.eteks.java2d.PJAGraphicsEnvironment 
-Dawt.toolkit=com.eteks.awt.PJAToolkit 
-Djava.awt.fonts=/usr/j2se/jre/lib/fonts'
export CATALINA_OPTS


my tomcat start up confirms this 

sandpit [sparc] 14% ./startup.sh
Guessing CATALINA_HOME from catalina.sh to ./..
Setting CATALINA_HOME to ./..
Using CLASSPATH:
./../bin/bootstrap.jar:/usr/j2se/lib/tools.jar:/usr/j2se/jre/lib/pja.jar
:/usr/j2se/jre/lib/pjatools.jar
Using CATALINA_BASE: ./..
Using CATALINA_HOME: ./..
Using JAVA_HOME: /usr/j2se
Using CATALINA_OPTS: 
-Djava.awt.graphicsenv=com.eteks.java2d.PJAGraphicsEnvironment 
-Dawt.toolkit=com.eteks.awt.PJAToolkit 
-Djava.awt.fonts=/usr/j2se/jre/lib/fonts


Tomcat works as expected.

Cocoon is deployed as a war file (and has been redeployed several
times), 
but it still doesn't work I get the usual sitemap error page. 
The errors in cocoons error log to match this are are:

Searching the Cocoon mail archives?

[Derek Hohls]

Hi

A quick (and somewhat redfaced question) - how do I search the archives
at:
http://www.mail-archive.com/cocoon-users@xml.apache.org

for multiple AND instances (eg. sun+svg+sitemap)

Thanks!

I don't know Struts, so I can't compare the two. Anyway:
Validation, yes. There's a FormValidatorAction that should be
sufficient for many (far from all!) purposes. Form population, I'd say, is
not really supported. Although there are mechanisms that help a lot.

Unfortunately, yes, you're wrong. Both projects never took off because
of lack of developer resources. Some ideas have made it in some way or
another into Cocoon, however.
