SOAPRequestHander problem on client side
I'm trying to implement a client that consumes conversational web services, following this example Accessing Seam WebServices from a standalone Client, i get the following exception :

in order to test my conversational web services i've modified the test javascript in seambay and it works with the test javascript, that means i have probably problem only on the client side.
Client :
...
import com.itemis.jbpmclient.ws.SOAPRequestHandler;
@Name("client")
public class JbpmClient {
private SOAPRequestHandler soapRequestHandler = new SOAPRequestHandler();
@Begin
public void getProcessDefinition() {
System.out.println("JbpmClient:: before processMgmtService.getProcessDefinition");
JbpmService processMgmtService = new JbpmService_Service().getJbpmServicePort();
BindingProvider bp = (BindingProvider)processMgmtService;
ArrayList l = new ArrayList();
l.add(soapRequestHandler);
bp.getBinding().setHandlerChain(l);
processMgmtService.getProcessDefinition();
System.out.println("JbpmClient:: after processMgmtService.getProcessDefinition");
}
public void executeProcess() {
System.out.println("JbpmClient:: before processMgmtService.executeProcess");
JbpmService processMgmtService = new JbpmService_Service().getJbpmServicePort();
BindingProvider bp = (BindingProvider)processMgmtService;
ArrayList l = new ArrayList();
l.add(soapRequestHandler);
bp.getBinding().setHandlerChain(l);
processMgmtService.executeProcess();
System.out.println("JbpmClient:: after processMgmtService.executeProcess");
}
}Web services :
@Stateless
@Name("jbpmService")
@WebService(name = "JbpmService", serviceName = "JbpmService")
public class ProcessMgmtServiceBean implements ProcessMgmtServiceRemote {
@WebMethod
public String getProcessDefinition() {
System.out.println("ProcessMgmtServiceBean::getProcessDefinition:: current conversation id : " + getCurrentConversation());
ProcessMgmtBean processMgmt = getProcessMgmt();
return processMgmt.uploadProcessDefinition();
}
@WebMethod
public String executeProcess() {
System.out.println("ProcessMgmtServiceBean::executeProcess:: current conversation id : " + getCurrentConversation());
ProcessMgmtBean processMgmt = getProcessMgmt();
return processMgmt.createProcessInstance();
}
private ProcessMgmtBean getProcessMgmt() {
System.out.println("ProcessMgmtServiceBean::getProcessMgmt:: current conversation id : " + getCurrentConversation());
return (ProcessMgmtBean)Component.getInstance(ProcessMgmtBean.class, true);
}
private String getCurrentConversation() {
return Conversation.instance().getId();
}
}Conversational seam component :
@Conversational
@Scope(value=ScopeType.CONVERSATION)
@Name("processMgmt")
public class ProcessMgmtBean implements Serializable {
private ProcessDefinition processDefinition;
private ProcessInstance processInstance;
private ContextInstance contextInstance;
...
@Begin(join = true)
public String uploadProcessDefinition() {
//processDefinition = ProcessDefinition.parseXmlString(new String(processDefinitionFile));
System.out.println("ProcessMgmtBean::uploadProcessDefinition:: current conversation : " + getCurrentConversation());
processDefinition = ProcessDefinition.parseXmlString(
"<process-definition name='AddressCleaner'>" +
"<start-state name='start'>" +
"<transition to='end'></transition>" +
"</start-state>" +
"<end-state name='end'></end-state>" +
"</process-definition>"
);
return "successful";
}
public String createProcessInstance() {
System.out.println("ProcessMgmtBean::createProcessInstance:: current conversation : " + getCurrentConversation());
processInstance = new ProcessInstance(processDefinition);
rootToken = processInstance.getRootToken();
displayStatus(processInstance);
return "successful";
}
...
public void displayStatus(ProcessInstance instance) {
String nodeName = instance.getRootToken().getNode().getName();
System.out.println("You are now in node: "+nodeName);
}
private String getCurrentConversation() {
return Conversation.instance().getId();
}
@End
public void end() {}
}Thanks in advance for any hints and suggestion !!!
