    jBPM 5.2 issue Jboss7.1Beta

    pushpak1981 Novice

      Hi

      We have setup jBPM5.2 on JBoss7.1Beta when we try to execute sample business process we get the following error.

       

      Caused by: java.lang.IllegalAccessException: Class org.mvel2.optimizers.impl.refl.ReflectiveAccessorOptimizer can not access a member of class org.jboss.stdio.StdioContext$DelegatingPrintStream with modifiers "public"

      Below is the sample bpmn we are trying to deploy:

      Are we missing any configuration for JBoss7 ?

          Hi

          we have the same problem, with this code snip.

           

          try {
            InitialContext ctx= new InitialContext();
            kbi=(KnowledgeBaseInterface)ctx.lookup("java:global/examplejbpm5/KnowledgeBaseEJB!it.comp.example.jbpm5.KnowledgeBaseInterface");
          } catch (NamingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
          }

           

          KnowledgeBase kbase= kbi.getKB();

           

          EntityManagerFactory emf = Persistence.createEntityManagerFactory("it.comp.example.jbpm5.jpa");
          Environment env = KnowledgeBaseFactory.newEnvironment();
          env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf);
          StatefulKnowledgeSession ksession = JPAKnowledgeService.newStatefulKnowledgeSession(kbase, null, env);
          ProcessInstance pi = ksession.getProcessInstance(1);
          if (pi == null) {
            Map<String, Object> params = new HashMap<String, Object>();
            params.put("employee", "krisv");
            params.put("reason", "Yearly performance evaluation");
            pi = ksession.startProcess("sayhello", params);   // <--- exception

            Hi push,

             

            I solved.

             

            Change the system.out to something like this:

             

            org.jboss.logging.Logger.getLogger(&quot;wwww&quot;).error(&quot;Ciao&quot;);

             

            System.out involves a call to a private nested class method  which can't be run inside a script... (I suppose)

             

            Vit
