I had a JSR-109 Web Service client that was working perfectly with JBoss 4.0.4.GA and JBossWS 1.0.2.GA. I just upgraded to 1.0.3.GA, used the new libraries to generate the stubs in the client, rebuilt, redeployed the client, and now I am getting this exception when I invoke the client. 14:43:14,709
