Hi,
I had the same problem: Clarity uses JAX-WS, part of Java 6 / 7, on the exposed webservices, while Axis is an JAX-RPC implementation and does not work.
I solved the problem to connect to Clarity using the NetBeansIDE 7.0.1 IDE. Includes an assistant to connect to webservices that worked for me. Uses JAX-WS as a client to web services.
Hope this helps
Best regards,
Víctor
