Another suggestion is to run the stylesheet outside of Cocoon using 
Xalan (since that is what Cocoon uses by default) and see if Xalan gives 
any specific errors. (One way to do this is to download the trial 
version of Oxygen (oxygenxml.com) and do a "Validate" on the stylesheet.)


Or, after getting this error in Cocoon, look in the logs error.log and 
core.log; they are usually more helpful than sitemap.log, in my experience.
Look for an error that says unable to create transformer, accompanied by 
an error message about a problem in the stylesheet.


Third suggestion: show us the stylesheet.

Re: XSLT transformation

[Marc Salvetti]

Yes, this is the expected behavior, the pipe will always stop at the 
first serializer, or before if there is an error, no matter what's after 
it. I just left the second transform because i always use this technique 
to debug my pipes : moving a serialize type="xml"  line to differents 
places in the pipe to figure the guilty transform.


So in your case, .if the following give no error

 
 
 

It just means your bdbxml class is ok.
So you can look for the pb in containerslist.xsl

[CFORM] How can I remove a previous validation error from a widget?

[Dan Ochs]

Hi everyone, I'm trying to do some javascript validation with my form
that validates that at least one out of two fields are filled in.  I
put the validation element and javascript under the form element and
the validation works fine the first time I execute it.  In the
validation code I set the validation error on the SECOND of the two
widgets.

If I try to submit the form without filling in any data the first
time, the validation works fine.  Then if I fix the problem by filling
in some data in the FIRST field and resubmit, the validation still
fails.  If I fix the problem by filling in some data in the SECOND
field and resubmit, the validtion works correctly.  So, I think what I
need to do is clear the validation error from the SECOND field, but
I'm not sure how to do this.

I set the error on the field by doing:
if (isvalid==false){
   form.lookupWidget("fieldId").setValidationError(new
Packages.org.apache.cocoon.forms.validation.ValidationError("error_key",true)));
}

I have tried removing the validation error by doing this, and the
validation error is removed, but the form does not submit and I get
the page back again, but without any errors. (So I have to click
submit twice after the error is fixed)
else{
   form.lookupWidget("fieldId").setValidationError(null);
}


Anyone have any suggestions of how to implement this or a way I should
reorganize my form to get this to work properly?

thanks!
dan

Re: CForms - adding style to labels

[footh]

Yes, that put me on the right track.  I was thrown off
this track because I changed the
forms-pages-styling.xsl and the changes did show up. 
However, that is "included" in the main page, not
"imported".  In fact, it turns out I had to alter the
forms-advanced-fields-styling.xsl because that is
where forms-fields-styling.xsl is imported.

It should definitely not take that long! For us it took 5 minutes to 
transform a bigger sitemap to Java and compile it.



My sitemap has about 100 pipelines and runs on tomcat5.0.14 and uses cocoon 2.0 
engine.


How huge is it?? Is there any chance to port your application to 2.1 or 
most recent 2.0? There you will have the interpreted sitemap which 
should solve your problem. But it will still consume many resources. 
Think about splitting your sitemap into subsitemaps and mount them from 
a much littler root sitemap. This is true for both the compiled and the 
interpreted sitemap.

sitemap...? 

=

A fair question.

The scenario is this: Authors create documentation in XML, and no one is
to touch the XML documentation except the author or an editor.

The documentation is created either statically, using Ant, or
dynamically, by simply dropping the XML source files into a directory
under Cocoon.

These source files contain references that pull menus and other "stuff"
into the HTML, PDF, or whatever is created. Again, these XSLs are not to
be touched by anyone other than the authorized personnel.

So, I can only call these XML and XSL files, not modify them. With me so
far? ;)

OK. So, now we have these files that contain content, and they also
contain menus to other content files.

Now we want to drop these XML files containing content into a directory,
and aggregate them with newsfeeds, something like a portal, but without
the necessity of authentication.

While I could do the aggregation in the sitemap, I would have to create
a new matcher every time a new source file was created, thus always
having to update the sitemap.

By using a single "aggregate.xml" file to call the ever-changing content
files, I can use the wildcard matcher. Thus, however many content files
are added or deleted, the sitemap does not have to change.

Make sense?

So, the ideal thing would be a sitemap matcher like the following:

  




  

...where the "index.xsl" is an override that calls the pre-existing XSL
and my code that transforms the RSS newsfeeds and whatever other
overrides I need to make.

Now, the "aggregate.xml" would call the content file requested by the user:

http://apache.org/cocoon/include/1.0";>





And the missing piece(s) of the puzzle are:

1. Given a request from the client for "http://mydomain/foo";, how to
capture "foo" in a variable in the sitemap, and
2. Pass that variable in the place of {REQUESTED URL} in the
"aggregate.xml" above.

Further suggestions would be welcomed, and I would even buy you a beer
in San Diego in December.

Well, you'd generate the XML from a template.  Using either the 
JXTemplateGenerator or the Velocity generator, you can use the 
${request} variable to get at the request URI directly, or you can pass 
it in as a sitemap parameter and use the ${parameters} object to access 
it within the template.


Or you could run the XML file (the one containing the cincludes) 
through an XSLT transformer, using a stylesheet that substitutes from a 
stylesheet parameter, before it hits the CIncludeTransformer.


I'm curious though why you don't want to do the aggregation in the 
sitemap...?

This is because you have to touch the main stylesheet 
forms-samples-styling. Otherwise cocoon will not detect changes in 
imported stylesheets and will still transform your forms using cached 
instance.

ok. I thought you just wanted this use case to work.

In order to pass a parameter to your "file" you can either:

1) use a generator (like jx or xsp or a custom one) and pass that 
parameter from the sitemap:


  


in jx you can read the parameter the using 
${cocoon.parameters.getParameter( "uri" )}
(you may want to check the syntax - it may differ in 2.1 and in cocoon 
trunk due to some refactorings)


2) apply a stylesheet to your base file and parametrize it the same way 
I did at 1)

Just remember that XML Spy does not use the same XSLT transformer as Cocoon.
I think there is an error in your stylesheet. Try to comment out some

transformer ( referenced as type="bdbxml") which returns XML results.
This all works fine if I use   to simply
output the XML, however if I try to transform the XML output with the
XSLT transformer above I get an error:

>> Error executing pipeline.

>> org.apache.cocoon.ProcessingException: Error executing pipeline.: 
>> java.lang.RuntimeException

I know the XSLT containerslist.xsl is correct as I've tried it against
some sample output XML in XMLSpy, but it appears that when I add this
XSLT transformer I get a Processing Exception? 

In the sitemap.log it is reported as:

Unable to get parser: java.lang.RuntimeException:
java.lang.NullPointerException

Any ideas please? (for a Cocoon newbie)
Thx in advance,
Ant

Graphing standards

[Ron Wheeler]

Is there a generally accepted notation for documenting pipelines.

What symbols are used for aggregate, source, transform serialize, etc?

Strange problem upgrading Tomcat/Cocoon

[Steve Burling]

I'm starting the process of upgrading our Tomcat/Cocoon install, currently 
Tomcat 5.0.16 and Cocoon 2.1.3, wanting to move to Tomcat 5.5.9 and Cocoon 
2.1.7.  I've run into a problem that I can't explain, and hope that someone 
else has seen (and solved!) the problem.


Our web/Tomcat/Cocoon server is a Sun ES3500, running Solaris 8 (uname says 
SunOS hostname 5.8 Generic_117350-25 sun4u sparc).  A vanilla install of 
Tomcat, with an un-modified server.xml, starts up just fine.  If I copy the 
cocoon.war file that results from un-tarring the Cocoon 2.1.7 distribution 
and typing "build.sh war" into Tomcat's webapps directory, the Tomcat 
startup hangs right after logging "Scheduler 
Cocoon_$_Wed_Aug_03_11:26:06_EDT_2005 started."


I've done this install on two other test machines, one a Dell box running 
Red Hat Enterprise AS 4.1, and one another Sun box running the same version 
of Solaris as the problem box.  Both installs work fine, and Tomcat starts 
up fine with Cocoon installed.  So I'm completely mystified.


I've attempted to find any reference to this problem in the list archives 
and via Google, and did find one post that claims that Cocoon and Tomcat 
5.5 simply aren't compatible, but my tests show that it works fine 
everywhere I've tried it *except* on our production server.  Any help would 
be greatly appreciated.

JNDI Problem

[Stundzig, Steffen]

Hi folks,

I've a problem with a jndi lookup in my Action class. I've read the
guides and searched the mail archives, but I don't get it to work.

The config:
- web.xml
  
myvar
something
java.lang.String
  

- in my action impl  
  new InitialContext().lookup("java:comp/env/myvar");

but the lookup throws a NameNotFoundException: env not bound. The
Debugger affirmed it. If I do exactly the same with another servlet,
with the lookup code directly in the 'doGet'-method it works as
expected.

What can I do? Did I missed something?

I've tested it with cocoon 2.0.4 on JBoss 4.0.2/tomcat 5.0.28.


MfG
Steffen...

Hi,

I have just discovered the problem pictured in
http://marc.theaimsgroup.com/?l=xml-cocoon-dev&m=112297570819684&w=2


Adding to this is an issue with IE and the  tag. I did not
search the mail archive nor bugzilla, so maybe it is already addressed
for the next release.

The xhtml serializer will change
