Seam on Weblogic 10.3.2: Possible classloader problem?

Question

Hi all,
I have a problem deploying a Seam 2.2.0.GA application on WebLogic 10.3.2. I use JRockit 1.6.0_14, Richfaces 3.2.0.GA and Facelets 1.1.14 and the Server is deployed on Windoes XP 32bit. The application has the following structure:
application.ear
|--> APP-INF
| |--> classes
| |--> lib (all jar dependencies go here, including the WAR dependencies, EJB module dependencies)
|-->META_INF
| |--> application.xml
| |--> data-sources.xml
| |--> MANIFEST.MF
| |--> weblogic.xml
| |--> weblogic-application.xml
|--> jboss-seam-2.2.0.GA.jar (is an EJB module)
|--> myEjbModule1.jar
|--> myEjbModule2.jar
|--> myEjbModule3.jar
|--> myEjbModule4.jar
|--> myWar.war (NO libraries in WEB-INF/lib, finds everything in EAR/lib)
JBoss Seam is an EJB module. and is declared as such in application.xml. Everything is OK, since the application loads correctly. The jar contains a faces.config registering the SeamPhaseListener on JSF, so that Seam actually works.
Problems start when I try to enable the debug page of Seam. In order to do this, one must include in the classpath the jboss-seam-debug.jar (in APP-INF/lib or EAR/lib, here I am using the first). This jar has its own faces.config, which registers the Seam*Debug*PhaseListener on JSF, so that it catches debug requests.
When deploying WITH jboss-seam-debug.jar, the application does not appear, but ONLY the debug page with the following exception (stacktrace at the end):
Exception during request processing:
Caused by java.lang.IllegalStateException with message: "No phase id bound to current thread (*make sure you do not have two SeamPhaseListener instances installed*)"
This probably signifies a classloader issue. So, I have two questions:
1. Has anyone deployed JBoss Seam on WenLogic WITH the debug page? If yes, is the structure of my project correct?
2. Is there a way to debug the classloading of WebLogic? What I would find helpful would be to see what happens that registers the SeamPhaseListener more than one times.
Note: When "JBoss-izing" the same EAR (remove hibernate jars, which are provided by JBoss, and move all libraries from EAR/lib to EAR root), the application loads correctly. BOTH the application AND the debug page appear correctly.

Answer 1

The problem was the name of the Seam EJB module. Changing the jar to jboss-seam.jar, everything worked. This issue does not appear on JBoss 4.2.3.GA, where I also tested.
