Hi, I am also having the same problem. I am using JAX-WS 2.0.3 with jboss 4.0.5, and enabling mtom on the client side to send an attachment to the server. When I check the content of the msg in trace mode, it looks like it is inline. Is there anything else I need to do or maybe the trace mode is not showing the correct msg body? Any help would be appreciated. Thanks, View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4169113#...
