Hello,
I have recently started to use AXIS2 (1.4) (on J2EE 5/with the Sun Java
Application Server 9.1, usiing Java 6); the idea is to be able to create
SOAP-based webservices to rsolve certain problems.
Using plain AXIOM to generate client replies (these are generated based
on Database input) is not too hard; client and server side work fine.
However, as soon as i try to switch to SOAP basded Messaging), things go
wrong; i get the exception as listed below
This has probably been asked times and ties before.
Can anyone tell me what I a doing wrong?
