Bernard,

Thanks for the reply.  I'm still having some issues.  First, I placed a second copy of jsf-facelets here:
\jboss-4.2.2.GA\server\default\deploy\csimons.ear

I restarted JBoss and experienced the same error.

Next, I put jsf-facelets here and restarted:
\jboss-4.2.2.GA\server\default\lib

This seemed to work as I'm now getting a different set of errors.  Would you mind taking a look?  I have followed the examples to a T.  But it looks like JBoss doesn't like the <library-class> usage in elfunctions.taglib.xml.  I hope it's in the right folder.  Here is the full stack trace:

Samuel,

Thanks for the reply.  I also emailed Bernard as requested but I'm unable to send our EAR/WAR around as its proprietary.

We're using Seam 2.0 GA but considering upgrading soon.  The project was built using seam-gen but this was using seam-gen that came bundled with Seam 1.2GA.  The application has grown quite large and has been modified often but the extend of our .ear/.war folder layout has changed little, if at all.  At the end of this email I break out the EAR structure...

I have to let you know that the only jsf-facelets anywhere in our JBoss server directory was /WEB-INF/lib prior to adding it to some other directories to see if it would catch.  In fact, it did catch once I added it to my ./ear root directory, but then received a number of errors as I described above.

So you recommend I should remove it everywhere again and report back?  I will do just that...

EAR structure (project):

/view
 + /view/WEB-INF
 + /view/META-INF/elfunctions.tablig.xml
/src
/resources
/lib (this is where jsf-facelets.jar is located)

Deployment structure:

/csimons.ear
+ /csimons.war
 + /WEB-INF
   + /lib (this is where jsf-facelets.jar is located)
+ /csimons.jar
+ /META-INF

Thanks!

Sam and Bernard,

When I go back to only having one jsf-facelets.jar, located at
C:\jboss-4.2.2.GA\server\default\deploy\csimons.ear\csimons.war\WEB-INF\lib

I get this stack trace as soon as I hit the login page:

Samuel,

Thanks for your support.  I am getting JBoss debug pages when I try to post the output from 'tree'.  Would you mind if I emailed it to you?

Thanks.

Hi Sam,

I believe I sent you my tree a while back; did you have a chance to test out Seam 2.0GA and the Custom EL functions described above?  I've tried to make do without this feature but I'm realizing that I might actually need it to do what I want...

I can confirm that jsf-facelets is in my project.war/web-inf/lib directory and only in this directory.

Thanks.

Just to update this thread...I have upgraded to Seam 2.1.SP1 recently and attempted to complete the example once again.  It continues to fail with a NoClassDefFound for AbstractTagLibrary.  Not sure where to go from here...jsf-facelets is where it is supposed to be.

Any suggestions?
