As far as I can tell, JBM can run on 4.0.x series without any major issues. I am running JBM 1.2.GA on 4.0.5.GA in Production! Although this is not advisable, due to many restrictions in the project, we have no option except running JBM on 4.0.5.GA. All seems well (except few minor quirks) so far. Related to your *how* question, follow the manual and deploy the JBM. Thanks Madhu View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4105949#...
