I meant I get the "multiple MBean" exception when I uncomment the XML configuration section denoted in the previous post.
I'm running this inside JBoss 4, and I'm not sure what this MBean does either - because it doesn't seem to have any methods I can call (looking at the JMX-console) to display information about the cache (unlike TreeCacheAop which does have some useful methods).
Perhaps it allows you to connect the GUI to the cache running inside JBoss, but I've not seen any instructions.
This is a bug. To get around for now, you can use the standalone GUI (see the tutorial) with the same JGroups channel. That will display you cache visually as well.
Can you please go to sourceforge, open a bug, and assign it to me so that I won't forget about it?
I had already used the described workaround...works like a charm! ;)
I'll make the bug report.
