TopLink and JBoss

Question

Hi everybody,
I have a weird problem.
I had recently completed SRDemo ADF tutorial, everything run fined, no problem.
Out of curiosity to see how the things are running JBoss, I try to deploy JBoss.
After long series of problem, I come this final one and I am hoping that somebody can give me a clue to which direction to proceed.
I am receving this exception from the Jboss,
JBO-29000: Exception [TOPLINK-6008] (Oracle TopLink - 10g Release 3 (10.1.3.1.0) (Build 061004)): oracle.toplink.exceptions.QueryException Exception-Beschreibung: Deskriptor für [oracle.srdemo.datamodel.Users] bei Abfrage namens [findUserByEMail] fehlt. (which basicly say it is not able to find the descriptor for the named query)
I have a feeling session is not able to locate SRMap.xml file as TopLink mapping file, otherwise why it should log such a message, when everything is running without problem in OC4J.
Any ideas?
Thx in advance.
Here is my sessions.xml

Hello,
How are you getting/creating your session, and what is the code you use to execute the query? The problem is that it can't find a descriptor for the class passed in, which sometimes can be caused by classloader issues - if the class object passed in was loaded with a different classloader than TopLink used to load them in during startup, the descriptor wont be found. If you are using the SessionManager and this is the problem, you will need to use the getSession api that allows you to specify a specific classloader, such as
getSession(sessionName, yourclass.class.getClassLoader())
Best Regards,
