Hi,

I am a new in jboss ESB, I am triyng to make JBPM and JBOSS ESB exchange().

my example is that jbpm calls ESB and get the response, when i test the esb using soapUI the process work fine, but using JBPM i have the exception below 

org.jboss.soa.esb.ConfigurationException: *No EPR present in process instance*
          at org.jboss.soa.esb.services.jbpm.actionhandlers.EsbActionHandler.execute(EsbActionHandler.java:137)

the java code :


     JbpmConfiguration jbpmConfiguration = JbpmConfiguration.getInstance(); 
     JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
 
     GraphSession graphSession = jbpmContext.getGraphSession();
     ProcessDefinition processDefinition =
                    graphSession.findLatestProcessDefinition("calcule");
 
     String a = request.getParameter("a");
     String b = request.getParameter("b");
 
     ProcessInstance processInstance = new ProcessInstance(processDefinition);
     Token token = processInstance.getRootToken();
     System.out.println(token.getNode().getName());
 
     ContextInstance contextInstance = processInstance.getContextInstance();
     contextInstance.setVariable("a", new Float(500));
     contextInstance.setVariable("b", new Float(500));
 
     processInstance.getRootToken().signal();
 




is there anything that i messed ?


for information i am using jboss-esb4.9,  jbpm 3.2  and jbossAS 5.1.0GA
