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

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
