Hi Petej, I am starting webservices recently. I have been doing some SOAP calls and XML Over HTTP previously. Now I just formalize my understanding of Web Services and SOA. I am just trying to undertstand the JAX-RPC services. As per the example in the tutorial it says putting the HelloWorldServlet in webservices.xml allows the class to be treated as pseudo-servlet so that's what I am trying to figure out why it is failing.
