Re: In Sample SB EBJ: IncompatibleClasschangeError: Implementiong Class

[john . jones]

I received the same error when I got started using Jonas. The transaction manager stuff in j2ee.jar conflicts with Jonas' transaction manager.
Unjar the J2EE.jar, and make a new jar with only the ejb classes in it. Take j2ee out of the classpath, and replace it with your new ejb.jar. That should fix it.

Hope this helps,
