Best way to mock complex soap responses

I have a Java method I want to Unit test, but it requires a mocked SOAP response which contains multiple lists and layers of nodes. I am doing t开发者_开发百科his with a handwritten mock i.e. just manually creating the objects and setting the values, but as the response is quite complex its a pain building up the response. I have a sample XML response is there an easy way of creating the mock using the XML?

Also I looked at Mockito and it looks fine for simple Objects, but it doesnt seem that good for complex responses (I may not be using it to its full potential).

The app stack is Java 1.6, Spring 3 and using JAX-WS.

I do something like this

@WebService 
public class MyWebService {

        @Autowired
        private ServiceBean serviceBean;

        public SomeReturedData getData(SomeInputData inputData) {
            return serviceBean.getData(inputData);
        } 
}

For my UnitTest, I have a mock instanciation of "ServiceBean" which I inject in to @MyWebService, and "MyWebService" is deployed using the "in-vm" transport as described here

By Using the in-vm transport, All the XML marshalling/unmarshalling is still done by the web-service framework ,and you only have to deal with Java part.

Now someone might ask, why not test the "ServiceBean" directly, why the need to deply a WS using in-vm transport ? Well 2 things, Using in-vm transport you get to test that the JAXB XML marshalling/unmarshalling is working correctly, and it also allows you to test any intercepting handlers that you might have defined for your webservice.
