Hi,

You cut the trace just at the line where it could have become interesting. Could you provide a bit more?

Basically java.lang.NoClassDefFoundError means that you're missing a jar file on your class path - but without other information it is not possible to say more.

Thank you for your quick response!

I copied all messages. After the "java.lang.NoClassDefFoundError" message the program stops.

I will check the jar files.

You where right. I forgot a jarfile.
But now I get this exception.

The problem is with the ID generator you've specified in your Class mapping files - you're using an unsupported value of "vm".

The supported ID generators can be found here:
http://www.hibernate.org/hib_docs/v3/reference/en/html_single/#mapping-declaration-id-generator

Also, are you migrating up from Hibernate 2? The net.sf reference is to the EHCache provider - if you look at the package naming section of the following migration guide that will explain the steps necessary to remove the warning.

Migration Guide: http://www.hibernate.org/250.html
