[jboss-jira] [JBoss JIRA] (JBAS-9424) MDB's are started *BEFORE* EJB's are jndi-bound

MDB's are started *BEFORE* EJB's are jndi-bound ----------------------------------------------- Key: JBAS-9424 URL: https://issues.jboss.org/browse/JBAS-9424 Project: Legacy JBoss Application Server 6 Issue Type: Bug Security Level: Public(Everyone can see) Components: EJB, Weld/CDI Affects Versions: 6.0.0.Final Environment: All (*NIX, Mac-Os-X and Win) Reporter: Bernard Ligny Priority: Critical Labels: community_contributor_needed Fix For: Open To Community I recently noticed a very strange behaviour (with JBOSS AS 6) with Message-Driven-Beans where we inject EJB. If the JMS queue is empty when the jboss server is started, then everything works fine. If, no luck, the jms queue is *NOT* empty, my MDB is apparently mounted *BEFORE* the ejb's and the @Inject failed: => "Failure WELD-000079 Could not find the EJB in JNDI: class xxx" I further investigated the problem: I replaced the @Inject annotation, with a "manual" lookup of my ejb using the javax.enterprise.inject.spi.BeanManager capabilities (that i put in a @Postcontruct method of my MDB), The trick consisted in trying the lookup n times with a delay of x sec between each attempt. Here are the results (excerpt from server.log): {code:xml} 2011-07-28 12:05:06,180 INFO [STDOUT] (Thread-0 (group:HornetQ-client-global-threads-183899831)) *** [1] Trying to lookup KernelResources 2011-07-28 12:05:06,190 INFO [STDOUT] (Thread-0 (group:HornetQ-client-global-threads-183899831)) *** [1] Failure WELD-000079 Could not find the EJB in JNDI: class net.haulogy.energycomm.kernel.org$jboss$weld$bean-jboss$classloader:id="vfs:$$$Users$bli$Devware$jboss-6$0$0$Dev$server$default$deploy$energycomm-ear$ear"-SessionBean-KernelResources_$$_WeldProxy ... 2011-07-28 12:05:11,191 INFO [STDOUT] (Thread-0 (group:HornetQ-client-global-threads-183899831)) *** [2] Trying to lookup KernelResources 2011-07-28 12:05:11,192 INFO [STDOUT] (Thread-0 (group:HornetQ-client-global-threads-183899831)) *** [2] Failure WELD-000079 Could not find the EJB in JNDI: class net.haulogy.energycomm.kernel.org$jboss$weld$bean-jboss$classloader:id="vfs:$$$Users$bli$Devware$jboss-6$0$0$Dev$server$default$deploy$energycomm-ear$ear"-SessionBean-KernelResources_$$_WeldProxy ... 2011-07-28 12:05:16,193 INFO [STDOUT] (Thread-0 (group:HornetQ-client-global-threads-183899831)) *** [3] Trying to lookup KernelResources 2011-07-28 12:05:16,193 INFO [STDOUT] (Thread-0 (group:HornetQ-client-global-threads-183899831)) *** [3] Failure WELD-000079 Could not find the EJB in JNDI: class net.haulogy.energycomm.kernel.org$jboss$weld$bean-jboss$classloader:id="vfs:$$$Users$bli$Devware$jboss-6$0$0$Dev$server$default$deploy$energycomm-ear$ear"-SessionBean-KernelResources_$$_WeldProxy ... 2011-07-28 12:05:21,194 INFO [STDOUT] (Thread-0 (group:HornetQ-client-global-threads-183899831)) *** [4] Trying to lookup KernelResources 2011-07-28 12:05:21,194 INFO [STDOUT] (Thread-0 (group:HornetQ-client-global-threads-183899831)) *** [4] Failure WELD-000079 Could not find the EJB in JNDI: class net.haulogy.energycomm.kernel.org$jboss$weld$bean-jboss$classloader:id="vfs:$$$Users$bli$Devware$jboss-6$0$0$Dev$server$default$deploy$energycomm-ear$ear"-SessionBean-KernelResources_$$_WeldProxy ... 2011-07-28 12:05:26,195 INFO [STDOUT] (Thread-0 (group:HornetQ-client-global-threads-183899831)) *** [5] Trying to lookup KernelResources 2011-07-28 12:05:26,195 INFO [STDOUT] (Thread-0 (group:HornetQ-client-global-threads-183899831)) *** [5] Failure WELD-000079 Could not find the EJB in JNDI: class net.haulogy.energycomm.kernel.org$jboss$weld$bean-jboss$classloader:id="vfs:$$$Users$bli$Devware$jboss-6$0$0$Dev$server$default$deploy$energycomm-ear$ear"-SessionBean-KernelResources_$$_WeldProxy ... 2011-07-28 12:05:26,215 INFO [org.jboss.ejb3.nointerface.impl.jndi.AbstractNoInterfaceViewBinder] (Thread-3) Binding the following entry in Global JNDI for bean:KernelResources => finally the EJB is bound ! 2011-07-28 12:05:31,196 INFO [STDOUT] (Thread-0 (group:HornetQ-client-global-threads-183899831)) *** [6] Trying to lookup KernelResources 2011-07-28 12:05:31,197 INFO [STDOUT] (Thread-0 (group:HornetQ-client-global-threads-183899831)) *** KernelResources = No-Interface view for endpoint [ jboss.j2ee:ear=energycomm-ear.ear,jar=energycomm-kernel-0.5.0-SNAPSHOT.jar,name=KernelResources,service=EJB3 ] => the 6th attempt now works :-) {code} Conclusion: according to me, there is no doubt: dependencies between MDB's and EJB's are not correctly managed by the app server. The app server should wait for all EJB's to be bound before activating the MDB. MDB are activated too early (especially when jms queue is not empty at starttime)
