Name and version of the database you are using:
DB2

Exception occurs when calling sessionFactory = new Configuration().configure().buildSessionFactory();

HibernateUtil is the same as in http://hibernate.org/42.html#A11

The deployed ear file includes asm.jar and cglib-2.1.3.jar. The asm.jar is version 1.5.3. Both are from the Hibernate 3.2.4 download. A jar file in this ear contains the mapping file, domain object and HibernateUtil. hibernate.cfg.xml is in the root of this jar. The MANIFEST.MF includes the dependencies to the asm.jar and cglib-2.1.3.jar and other required jars in the ear file.

I have looked at similar problems on the Hibernate forum suggesting that another version of asm.jar is in the servers classpath. I have searched to see if WebSphere has other versions of these jars in its classpath (or any other places), but I haven't found any. I can't find any versions of cglib-full either.

Hi,

I have the same version as yours but the visit method signature is:



Is is it the same for you ?

Solved the problem by including cglib-nodeps which includes asm instead of cglib and asm + asm-attrs in separate jars as distributed with Hibernate 3.2.x. Fixes the problem :-)

Could probably also have configured Hibernate to use javassist as bytecode provider to solve it as well but are not going to try since it is already working. Hope there are no serious issues with using the nodeps version with Hibernate. Thanks for the response.
