Problem accessing JWS webservice through BPEL

Question

Hi,
I have designed a small BPEL file with which I am trying to access through the BPEL console/a java application. I am getting the following error: -

I have set the transaction-timeout accordingly in the following files: -
1) domain.xml
2) orion-ejb-jar.xml
3) transaction-manager.xml
Following is the excerpt from the service: - [I am using JWS annotations]
@WebService
@WLHttpTransport(portName="ResponsibleOfficeSoapPort", serviceUri = "ResponsibleOfficeService")
@WSDL(exposed=true)
@SOAPBinding(parameterStyle=SOAPBinding.ParameterStyle.WRAPPED)
public class ResponsibleOffice {
     @WebMethod
     public void addResponsibility(String office, String airline, String pRecordLocator) {
          Responsibility aResponsibility = new Responsibility();
          aResponsibility.setResponsibleOffice(office);
          aResponsibility.setResponsibleAirline(airline);
          Customer cus = new Customer();
          cus.setRecordLocator(pRecordLocator);
          cus.setReponsibility(aResponsibility);
          ResponsibilityHelper.persist(cus);
Following the BPEL file: -
<?xml version = "1.0" encoding = "UTF-8" ?>

Can someone please help on this?
Thanks.

Answer 1

Your webservice seems to be throwing the error:
Unable to find xml element for parameter: officeLooking at your BPEL process, you are assigning nothing to the inputVariable of your Invoke block, Invoke_1_addResponsibility_InputVariable. This means you are not sending any value in the office XML element.
<sequence name="main">
<!-- Receive input from requestor. (Note: This maps to operation defined in TestBPEL.wsdl) -->
<receive name="receiveInput" partnerLink="client" portType="client:TestBPEL"
operation="process" variable="inputVariable" createInstance="yes"/>
<!-- Generate reply to synchronous request -->
<*invoke* name="Invoke_1" partnerLink="ResponsibleOfficeServiceDefinitions"
portType="ns1:ResponsibleOffice" operation="addResponsibility"
inputVariable="Invoke_1_addResponsibility_InputVariable"
outputVariable="Invoke_1_addResponsibility_OutputVariable"/>
You'll want to assign something to the variable before you invoke the servie. Otherwise, you just get the same result every time you run it.
When you do run your process from the BPEL console, you can look on the Flow tab for that instance. Doubleclick on the INVOKE block, and you will see the XML that got sent to your web service.
