You should ensure that the deployment descriptors have the corresponding JNDI name. When you are AAT make sure the EJB you are trying to reference has that name in there.
I think when you install WSAD you are supposed to select CVS as your source control system. You can either re-install or just install their CVS portion. I think if you search IBM's site there is a paper on how to exactly that. Hope that helps Faisal [ June 03, 2002: Message edited by: Faisal Dosani ]
Well you can use Java to implement Web services or C# or even Perl I beleive. It is up to you. In the end SOAP is just XML. The Clients and Servers are written in whatever language you like and the information is exchanged via SOAP. This helps Web Services in being platform neutral.
Where are you defining the datasource? If you are using a tool like WS Application Developer then it would be in the server configuration / instance. Check that the name you have given to the datasource is correct. You obviously are not referencing it with the correct name. check that first.
Sounds like a great opportunity. I'd really be interested but I really haven't had a chance to play much with J2EE 1.3, only 1.2 I'm interested to see how WAS 5.0 works out. Are you still looking for people to help out?
