Hi All I am facing a very strange problem. I have devloped web services and deployed syccessfully on jboss4.0.3. Everything is working fine. But when i switched to jboss4.2.1, I was able to deployed the web service again successfuly. But when i am try to access any servies, it returns emptyString error. Actually on i checked the server log, parameters send by client is not available at the server side. But the same code works fine if i do it on jboss4.0.3.
