This morning I was helping a customer to debug some Web Services deployment issues, when I simply realized that the error was coming from the fact that he was trying to deploy a JAX-RPC service on a OracleAS 10gR2 server; where it is not supported/available.
This give me the opportunity to clarify the different versions of the Oracle Application Server and their related Java Enterprise Edition release support.
