[jboss-as7-dev] Listening for EJBs appearing / JNDI registrations

Hi, I have a piece of code that needs to kick into action when a particular EJB is registered. What would be the best way to do this? The code is in user-space, it's an OSGi bundle that needs to do something once the EJB is available... So I thought about the following: * register a DeploymentUnitProcessor, however this is a bit heavyweight to ask a EJB/OSGi developer to do... * maybe register an MSC service that waits for an MSC service registered by the EJB to appear? this is also a bit heavyweight and I don't think the MSC services registered by the EJB are documented/part of the public API... * It would be nice if I could simply listen for the JNDI registration... is that possible? As a workaround, I also thought about this: * If I deploy my artifacts in a certain order, will the appserver deploy them again in the same order on a restart? Thanks, David
