    Issue on Starting jBPM from External Client.

    NageswaraRao Ch Newbie

      Hi,

      I am trying to invoke process from the External Client as Servlet.

      I have the below code


      JbpmConfiguration jbpmConfiguration = JbpmConfiguration.getInstance();
      System.out.println("###Starting from the jBPM"+jbpmConfiguration);

      jbpmContext = jbpmConfiguration.createJbpmContext();

      System.out.println("###Starting from the jBPM"+jbpmContext);

      processInstance = jbpmContext.newProcessInstance("websale");


      System.out.println("###processInstance"+processInstance);

      //contextInstance = processInstance.getContextInstance();

      //contextInstance.setVariable("var", "abc");

      processInstance.getRootToken().signal();


      In place of the First line, I have tried in various options

      /JbpmConfiguration jbpmConfiguration = JbpmConfiguration.parseResource("org/jbpm/default.jbpm.cfg.xml");.

      Either way I could not suceed the execution. I am hitting the below error.
