I'm having the same problem.
Have you solve this problem since your first post?
Thanks in advance
I manage to get it work but there is some problem with Doc/Lit web service in JBoss.Net.
The problem is when my web method accepts more than one parameters, the 2nd, 3rd... parameter will always get null value. It works fine if the web method is only accepts 1 parameter.
