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

<?xml version="1.0"?><jbossesb parameterReloadSecs="5"xmlns="http://anonsvn.labs.jboss.com/labs/jbossesb/trunk/product/etc/schemas/xml/jbossesb-1.3.0.xsd"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://anonsvn.labs.jboss.com/labs/jbossesb/trunk/product/etc/schemas/xml/jbossesb-1.3.0.xsdhttp://anonsvn.jboss.org/repos/labs/labs/jbossesb/trunk/product/etc/schemas/xml/jbossesb-1.3.0.xsd"><providers>  <jbr-provider name="ibaSommeHttpGateway" protocol="http">   <jbr-bus busid="ibaSommeHttpGateway" port="9999"/>  </jbr-provider>  <jbr-provider name="ibaMultiplicationHttpGateway" protocol="http">   <jbr-bus busid="ibaMultiplicationHttpGateway" port="7777"/>  </jbr-provider></providers><services><service category="Calcule"   description="calcule la somme de deux valeurs" invmScope="GLOBAL" name="somme">   <listeners>    <jbr-listener busidref="ibaSommeHttpGateway" is-gateway="true" name="ibaHttpSommeGatewayListener"/>   </listeners>   <actions mep="RequestResponse">    <action class="org.jboss.soa.esb.actions.routing.http.HttpRouter" name="ibaSommeHttpRouter">     <property name="method" value="POST"/>     <property name="endpointUrl" value="http://localhost:8080/somme/SommeService?wsdl"/>     <property name="endpointAdresse" value="http://localhost:8080/somme/SommeService?wsdl"/>     <property name="reply-to-originator" value="true"/>    </action>    <action class="org.jboss.soa.esb.actions.SystemPrintln" name="message">     <property name="message" value="in the somme yoooou pi ESB"/>    </action>   </actions>  </service>  <service category="Calcule"   description="calcule la multiplication de deux valeurs"   invmScope="GLOBAL" name="multiplication">   <listeners>    <jbr-listener busidref="ibaMultiplicationHttpGateway"     is-gateway="true" name="ibaHttpMultiGatewayListener"/>   </listeners>   <actions mep="RequestResponse">    <action class="org.jboss.soa.esb.actions.routing.http.HttpRouter" name="ibaMultiplicationHttpRouter">     <property name="method" value="POST"/>     <property name="endpointUrl" value="http://localhost:8080/multiplication/MultiplicationService?wsdl"/>      <property name="reply-to-originator" value="true"/>    </action>    <action class="org.jboss.soa.esb.actions.SystemPrintln" name="message">     <property name="message" value="in the multiplication ESB"/>    </action>   </actions>  </service></services></jbossesb>




and the precessdefinition.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
