I think this is the right way to go, but means that there needs to be a inflow interface between Axis/JST109 and Geronimo. The 'hack' I was referring to was some magic interceptor hooked into the EJBObject stack that tweaked the regular invocation into a web-service one. I think this is the wrong way to go. There's no panic here - I just wanted to raise the issue that simple invocation through the remote interface, as indicated in the wiki, may not be the way to go. -- jeremy
