I already successfully ported my mySQL-DB to DB2-DB, but I'm still having troubles in Websphere.
Does anybody have an idea what could be wrong?

The hibernate.hbm.xml is situated in the root of my WAR-file (inside my EAR).

Not sure the root of a War is on the CP.

But the same ear worked perfectly on JBoss. What should I do than, to fix this problem?

1. repect the WAR structure as defined by the J2EE spec
2. show me the detailed structure, I'll help you

Hmmm, I thought I had respected that structure and everything works just fine on JBoss... But Websphere just can't find the hibernate.hbm.xml config file...


OK, here is my WAR-Structure:

you must put hibernate2.jar in your WEb-INF/lib, to be sure the same classloader load hibernate and its cfg file.

It works on JBoss because it has some magic CL maganement, but this is not the strict Java2 classloading strategy

Hmmm.. that could have been the case. So I simply added the hibernate2.jar to my WEB-INF/lib folder and build my application again.

But this tip could not resolve my problem and it's still showing the "/hibernate.cfg.xml not found" message.

Ok, I managed to solve this problem by placing the hibernate.hbm.xml file in the ejb.jar file.

This is expected: the hibernate2.jar used was in another place and thus not the Webapp classloader
