I've solve the warning about the non-jar deployer. It was a error in a class path. I now have no error message during the launch of the app server but i still have the w4ee-client not bound problem when i try to reach the web service. The jar I was describing in my first post is included in a more complete ear file containing a lot of other jars and ejbs... Please, I've no ideas whats going wrong.
