    Javassist Enhancement failed: Duplicate Method error

    marinovm Jan 30, 2009 9:33 AM

      Hi there,

      I have a problem with some entities that I'm deploying in JBoss...I've added a post to the relevant forum for JBoss but since the problem seems to be a Javassist one I thought someone here might be able to explain what causes this problem..so:

      I have some related entities that cause this error:

      Can anyone give me an idea what is causing this error i.e. from a Javassist point of view? I'm guessing it's some sort of method definition conflict. Any suggestions welcomed =).

      P.S. if this question is inappropriate for this forum let me know.

      Many thanks,

      Matthew

          I am getting the same error. I am guessing it's a library issue but I have not been able to resolve it even after replacing libraries. Anyone have any ideas what the correct combination of libraries are for Hibernate 3.3.1 to work.

          I am using.
          JBoss 4.2.3
          Javassist 3.4.GA
          Hibernate 3.3.1
