    NoClassDefFoundError during deployment

    Steve Farkas Newbie

      I had an EJB deployed with CMP & CMR in Jboss 3.0

      It was working with my client. However, I added a
      few more fields to the EJB and it's table.

      I thought I had made all the proper changes to
      jbosscmp-jdbc.xml & ejb-jar.xml, but upon deploy
      I get a class not found error.

      The error trace doesn't mention which 'class' isn't found!?!!!

      I've retracted my steps back and removed the fields
      I added to the bean - with no luck. I've rechecked the xml several times.

      Anybody seen this before !? Do I debug/modify
      the code to give me more information !?

      argh.

          Update.

          We've noticed that the class not found error (during
          the createEntityContainer() code as per
          my original note) occurs shortly after
          a "sealing violation" on a jar ?

          A redeploy of the jar, to hopefully correct
          the sealing violation results in the class not
          found errors for any EJB - including the gangster
          CMP examples !

          Hmm. Judging by the lack of responses, this is
          only happening to us!?
