yes, you can deploy it, I have done it the following way: - put the cache MBean configuration in file named jboss-service.xml - put jboss-service.xml inside META-INF dir of a newly created SAR file (you can name it jbosscache.sar for example) - in your application's EAR you put the SAR at root level and in jboss-app.xml you add: <module> | <service>jbosscache.sar</service> | </module> That's it :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4197176#...
