Daniel,
What version of jaxws are you using with your program and where did you
get it from?
I suspect that there is a difference in the runtime you are using of
jaxws that comes with java 6
versus what you are using with java 5.
In your program try creating the service by instantiating the
service class.
HelloService helloService = new HelloService();
HelloPort hello = helloService.getHelloPort();
Please let us know if you have more problems-
Thanks,
Kathy
