Hi: I have this same error, I'm using a JDK 1.4.2_15, a jboss 4.0.3 and JbossMessaging 1.2. If I run my code (client publisher) in my local (standalone) pointing to a clustered messaging jboss AS (nodes in the same server created by the release-admin.xml), it works fine, but if I try to run my client from a different machine in the same intranet, I get this same error. Any ideas? Thanks. Alejandro View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4167983#...
