[jboss-user] [jBPM Users] - Issue on Starting jBPM from External Client.

[contactnagesh]

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.
