Hello,
I am new to web service and to websphere.
I developped a little "hello world" web service with WSAD 5.1. When I test =
it in WSAD it works perfectly (I tried several tutorials before, and all of=
them work in WSAD).

But when I try to deploy it on WAS 5.0 I have the following error :

Does anyone have an explanation for me ?
I really need help : I tried many things but nothing works ...
Thanks a lot !

The WebSphere Test Environment 5.0 in WSAD may have PTF applied.  I
think there were some changes in Web Services in WAS 5.0.2.  I would
check WAS and see the same level of PTF has been applied or not.
