JSR-181 by itself is server side only. When you develop a client to talk to a JSR-181 endpoint, you have to consume the wsdl using a tool (wstools), and generate a mapping file. You also can not reuse any of the annotated interfaces because the client and server are fundamentally disconnected, they might be different. JAX-WS solves this problem by describing how to use the annotations on the client side. When we release a Java EE 5 compliant server (jbossws 2.0) you will be able to do this. Until then you will have to use the standard Java EE 1.4 client API. -Jason View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3981172#...
