Hey Sang
I had posted an similar question about this code earlier. My
understanding
is that this is not correct...and thats fine..since this is not
a final release...
first, the cast should not be to the stub, but to the interface
and second the impl should not be directly accessed.
I think the current release of the api supports the ServiceFactory
interface (as per the specs) to do this.
So the eventual code should look like
// pass some properties
Service service = ServiceFactory.newInstance().createService(...);
HelloIF hello= (HelloIF)service.getPort(HelloIF.class);
hello.sayHello();
Hope this helps
/sam
