Hi Mariano, Just to add further .... we had problem in catching custom exceptions by .NET clients although Axis generated java clients worked fine. I think for .NET clients one has to do low-level job of handling XML and parsing it and then be able to get at the details of exception.
Mariano, I still think WSDL is the ONLY thing that is needed and as far as I know AXIS automatically subclass custom exceptions from AxisFaults. The point is all custom exceptions get wrapped up as AxisFaults. Another point custom exceptions are a known problem with DII clients. Initially, we tried with DII but then realised that its a problem and moved on to stubs approach and it worked.
