Changing response from "void" to "Element"

[techy_bolek]

I'm trying to expand the example from:
http://static.springsource.org/sprin.../tutorial.html
The example assumes no response is returned. I want to return a simple response including a success flag and an additional error string. I've defined the response type element in the xsd file and now I'm trying to modify the code to return a response.

@Endpoint
public class HolidayEndpoint {
......................
@Autowired
  public HolidayEndpoint(HumanResourceService humanResourceService)
      throws JDOMException {
.........
    }

  @PayloadRoot(namespace = NAMESPACE_URI, localPart = "HolidayRequest")
  public void handleHolidayRequest(@RequestPayload Element holidayRequest)
      throws Exception {
    
/*---- pare holidayRequest and invoke the service ----/*
}

I modified the handleHolidayRequest changing the return type to "Element" and manually constructing the Element object as the return value.

  @PayloadRoot(namespace = NAMESPACE_URI, localPart = "HolidayRequest")
  public Element handleHolidayRequest(@RequestPayload Element holidayRequest)
      throws Exception {

    /*---- pare holidayRequest and invoke the service ----/*

    Element responseElement = null;
    responseElement = new Element("HolidayResponse");
    responseElement.setAttribute("value", response.getValue().toString());
    responseElement.setAttribute("responseString", response.getResponseMessage());
    return responseElement;
  }

The code compiles fine. However, when trying to invoke the web service I get a Soap fault:

<SOAP-ENV:Fault>
         <faultcode>SOAP-ENV:Server</faultcode>
         <faultstring xml:lang="en">
         No adapter for endpoint [public org.jdom.Element 
         com.mycompany.hr.ws.HolidayEndpoint.handleHolidayRequest(org.jdom.Element) throws java.lang.Exception]: 
         Is your endpoint annotated with @Endpoint, or does it implement a supported interface like
         MessageHandler or PayloadEndpoint?</faultstring>
</SOAP-ENV:Fault>

Any advice? Please note that I got the original example to work just fine.

I just learned that when annotations are used then both the request and response parameters must be annotated with @RequestPyload and @ResponsePayload respectively.

Also, as a side note I was constructing the response incorrectly, ignoring the namespace. The correct way to create response would be:

Namespace namespace = Namespace.getNamespace("hr",MY_NAMESPACE_URI);
responseElement = new Element("HolidayResponse", namespace);
