Jboss ESB JBPM - No EPR present in process instance

[keljboss]

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)

my jboss-esb.xml

and the precessdefinition.xml

<?xml version="1.0" encoding="utf-8"?><process-definition xmlns="urn:jbpm.org:jpdl-3.2"          name="calcule">

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

thank you for your help

Cheers
