I'm not exactly sure where to post this one, but since most of the relevant log shows jboss remoting code, I'll start here.

I'm trying to deploy an EJB 2 MDB to JBoss 4.2.3.
Here are the points of interest:
JBoss Messaging 1.4.4
JBoss Remoting 2.2.3
ear deployment Isolated=true

Here's some of my initial findings:
1) If I turn off ear deployment isolation, this problem goes away (and apparently remoting is not used for the lookup in that scenerio.)
2) From this log and looking at the source, it looks like a JNDI lookup for java:/StdJMSPool is failing (returning null) - but I don't understanding why that's happening.

Let me know if you have any ideas. It's important to me to get make the ear deployment isolation work.
