    JBPM - EBJ

    Pascal Ravot Newbie

      I'm a newbie to JBPM and i'm trying to use ejb stub client in a Action Handler.
      I've created a very simple stateless session EJB 3.0 that replicates a string through a remote interface.
      I'm trying to instantiate this stub with the usual :

       try {
       InitialContext ctx = new InitialContext();
       kp = (dumKp) ctx.lookup("dumKP/dumKpBean/remote");
       } catch (Exception e) {
       System.err.println("Cannot find dumKP/dumKpBean/remote");

      provided on top of the execute methode.
      I'm facing a lot of pb ....
      Even though i've packed the interface dumpKp in a client jar
      added to the jbpm project (in deployment too), when running i got :

      8:59:42,750 ERROR [STDERR] javax.naming.CommunicationException [Root exception is java.lang.ClassNotFoundException: com.mccsoft.kp.dumKp (no security manager: RMI class loader disabled)]

      After a look to various forum i got an hint regarding the fact that a Security Manager was missing,
      So i added one and got Hibernate Transaction Error.

      To make a long story short, does anybody knows if it is
      simply possible to use ejb stub in a jbpm workflow
      and if yes is there some docs links somewhere.
      Thanx to all ....
