[jboss-user] Hello, and a question (of course) :-)

Hello, all ... I'm new to JBoss -- i'm a longtime C++ developer who has just inherited a J2EE codebase when the developer left. I've done some Java before, so I volunteered to maintain it (mistake #1), but the last time I did Java was 2001 and it wasn't using beans or anything. I'm hopeful that i'll learn a lot more about this as I work with it more. That being said, i've an issue i'm trying to solve. I have 2 JBoss apps (called RMs) that talk to a central JBoss app (a broker) via JGroups. RM #1, running on one host, successfully talks to the broker app. RM #2, running on another host, does not. The error messages in RM #2s log look like this: 2008-03-28 15:29:11,881 WARN [org.jgroups.protocols.pbcast.GMS] merge responses from subgroup coordinators <= 1 ([]). Cancelling merge 2008-03-28 15:29:11,881 ERROR [org.jgroups.protocols.pbcast.GMS] coords or merge_id == null 2008-03-28 15:29:11,881 ERROR [org.jgroups.protocols.pbcast.GMS] coords or merge_id == null I've done a lot of searching and haven't found much that describes how to fix this. I've also gone through a lot (though not all, there are dozens of them, many with dozens of params / attributes) of the beans via the jmx-console, comparing the RM that does talk to the broker with the RM that does not. So far, i've not found any differences. Any help would be _greatly_ appreciated :-) Regards, John Falling You - exploring the beauty of voice and sound http://www.fallingyou.com
