[jboss-user] [EJB 3.0] - Inject dependency on JMS topic into servlet on startup

Hello All, I have EAR with multiple EJB and single WAR inside. EJBs inject JMS administrative resources such as Destination and ConnectionFactory using @Resource annotation. They depend on the MBean which represents JMS Topic. MBean is configured in deployment descriptor within one of EJB and that works well. But when I try to apply the same dependency for servlet code (servlet is marked as load-on-startup in web.xml) and deploy EAR onto JBoss, it fails. This is happening (as I realized from logs) because JMS Topic has not been bound yet. If I don't mark servlet as load-on-startup, but rather invoke it after server has started, injection in servlet works well. What is the right way to specify that servlet does depend on the JMS resource (or MBean which represents this resource)?
