You say you can also, I am confused. Does this mean I should still put my ear with me MDB in the deploy-hasingleton directory? Also deploy-hasingleton is for the cluster! It will deploy once on the master when the master comes up. If the master goes down a node in the cluster will take over as the master and everything in deploy-hasingleton will now be deployed to this new master. Hence the services in deploy-hasingleton will only ever be deployed to one node. I tried to use the @Depends annotation And it does not work I get a deploy exception. My bean will not deploy becuase it is waiting on HASingletonDeploer. Not sure why this is happening. Has anyone used @Depends to solve the issue of trying to deploy a singleton MDB?
