To be more concrete in how I solved the "non-jar deployer" warning, It was the java path of the <service-interface> element in the application-client.xml that was wrong. And as i've had no response for the w4ee-client not bound problem, meaning that the service was not deployed, I've found another solution. The solution I've found is more complicated but it works. My solution was to include the service deployement with a bean definition. Hope this help. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3988078#...
