For this particular service, I don't really know. But take a look at the JNDI tree through the JNDI viewer and see if it's also available under a different name. Or look for docs that explain how to use this client external to EJBs... Sounds like I've managed to find a corner case that J2EE 1.4 doesn't cope for... The JNDIView MBean shows that my service-ref is not published under the java: or global JNDI contexts. Is there any way that I can do that, in addition to publishing it under the local java:comp/env context? Alternatively I guess I'll have to revert to J2SE-style Service invocation, which seems bizarre and excessive given all this code is in the same .war file... ;( View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4048659#...
