My environment:
1. Win2K
2. Apache Tomcat 5.0.24
3. Axis 1.2RC3
My application scenario:
I would like to use a single proxy web service that deals with
connecting to the various end web services from client applications. I
am trying to achieve this by using the request SOAP message to extract
pieces of information about the end service and then connect to them
dynamically using the SAAJ API within the proxy web service. I get the
following error (appended at the end) when I try to use a JAX-RPC
handler for the service. The error message obviously does not convey
much information for me to resolve the situation.
Any ideas that go toward resolving this issue would be appreciated.
