I've managed to reproduce the problem with a simple test, and marshalling
manually. If I run this code I get the same error:
LoginApplicationCallParameter lCallParam = new
LoginApplicationCallParameter();
lCallParam.setPassword("tim");
lCallParam.setUserName("tim");
LoginApplicationResponseParameter lResponseParam = new
LoginApplicationResponseParameter();
lResponseParam.setApplicationDate(new Date());
lResponseParam.setSecurityToken("fhkjhgkjdfhgkjhdfgkjdhfk");
lResponseParam.setUserName("tim");
IBindingFactory lBindingFactory1 =
BindingDirectory.getFactory(LoginApplicationCallParameter.class);
IMarshallingContext lMarshallContext1 =
lBindingFactory1.createMarshallingContext();
lMarshallContext1.setIndent(2);
lMarshallContext1.marshalDocument(lCallParam, "UTF-8", null, new
FileOutputStream("/home/tjs/LoginCall.xml"));
IBindingFactory lBindingFactory2 =
BindingDirectory.getFactory(LoginApplicationResponseParameter.class);
IMarshallingContext lMarshallContext2 =
lBindingFactory2.createMarshallingContext();
lMarshallContext2.setIndent(2);
lMarshallContext2.marshalDocument(lCallParam, "UTF-8", null,
new FileOutputStream("/home/tjs/LoginResponse.xml"));
The important thing to note is that both lMarshallContexts are passed the
lCallParameter, where the second one should have been passed
lResponseParameter (and if you do it works fine) So in the second case, I'm
trying to marshall lCallParameter given a factory from
LoginApplicationResponseParameter. The error is:
java.lang.NullPointerException

So all I need to do now is work out why when it's failing when returning from
the soap call. I presume it's trying to marshall with the wrong Factory
somehow. Any thoughts would be appreciated.
