    Deployment results in ClassFormatError

    Randahl Fink Isaksen Novice

      I have a set of EJBs which are deployable on a different EJB Server. However, when deploying on JBoss I get a ClassFormatError with a "repetitive method signature" message. My EJBs ar compiled with j2sdk1.4.0_01, so I do not really believe in the compiler creating an illegal class format containing a repetitive method signature. I had a hunch that the error was caused by my class inheriting the same interface twice (I have a complex inheritance hierarchy) but I checked up on that and it does not seem to be the problem - and even if I did inherit the interface twice, that is still legal Java, as we all know.

      I am really clueless, so if anyone has an idea what could be wrong I would really appreciate the post.
