      Hi we are two Jboss newbie and we have remote comunication problems with ejbBean!
      We use:
      - jboss 3.2.1 with jbuilder9
      - mysql
      - 2 Stateful Session EjbBean CMP (A and B) with all methods' attribute setted to REQUIRED


      Using local comunication (localhost for A and B) it's all OK!

      Our problem is: in bean A when we try to invoke a remote method of bean B (after we have made lookup of B):

      (on the server side [B side])
      jboss gives us the following message:

          Wohoh guys ...

          It seems to me that your session bean B is not serializable. The fact that you use statefull SB obliges JBoss to transmit data over the wire.

          Check the attribute (member) of session bean B. It should be simple (i.e. serializable) stuff.

          By the way you're in the wrong sub-cat. JMS has nothing to do with your problem.

          Regards,

          Stephane
