After a bit of testing: 1/ Removing the dependency towards jboss.j2ee:module=NavineoDock.jar,service=EJB3 eliminates the failure Deployment "jboss.j2ee:ear=Navineo.ear,jar=NavineoDock.jar,service=EJB3" is in error due to the following reason(s): ** NOT FOUND Depends on 'jboss.j2ee:ear=Navineo.ear,jar=NavineoDock.jar,service=EJB3' ** -->Conclusion: depends towards the module's EJB3 service seems to cause a circularity error? It didn't in JBoss4. 2/ After that i removed in all modules the depends pointing towards the modules' EJB3 services: indeed the EJB3 service isn't started completely by the time my business mbeans start (stacks about unknown jdbc connections) -->Conclusion: brutally removing all EJB3 service depends doesn't work View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4234694#...
