Error during hot redeployment when trying to use dependecies
I am trying to use the depends tag in the jboss.xml to handle deployment dependecies.
I have 3 EJBs TESTA, TESTB, and TESTC. TESTB and TESTC have the depends tag in the jboss.xml. If I deploy them first then they wait before trying to deploy like they are supposed to. Once TESTA is deployed both deploy and work properly. The problem occurs if I try and undeploy TESTA and then redeploy it. When undeploying the following appears in the log file which makes sense.
2006-10-12 15:37:05,950 DEBUG [org.jboss.system.ServiceController] destroying dependent services for: jboss.j2ee:service=EjbModule,module=TESTA.jar dependent services are: [ObjectName: jboss.j2ee:jndiName=local/testBBean@33317701,service=EJB State: STOPPED I Depend On: jboss.j2ee:module=TESTA.jar,service=EjbModule , ObjectName: jboss.j2ee:jndiName=testCBean,service=EJB State: STOPPED I Depend On: jboss.j2ee:module=TESTA.jar,service=EjbModule ]
Likewise on the redeploy a similar log comes up
2006-10-12 15:37:26,903 DEBUG [org.jboss.system.ServiceController] Creating dependent components for: jboss.j2ee:service=EjbModule,module=TESTA.jar dependents are: [ObjectName: jboss.j2ee:jndiName=local/testBBean@33317701,service=EJB State: DESTROYED I Depend On: jboss.j2ee:module=TESTA.jar,service=EjbModule , ObjectName: jboss.j2ee:jndiName=testCBean,service=EJB State: DESTROYED I Depend On: jboss.j2ee:module=TESTA.jar,service=EjbModule ]
this is where the problem occurs, when it tries to bring the other 2 dependants up the following errors are thrown:

Then TESTA finishes its deployment.
I am trying to figure out if this is the proper way to use the depends and if depends is supposed to work for redeployments.
For completeness here are the 2 jboss.xml files for the dependent beans.
<jboss> <enterprise-beans> <message-driven> <ejb-name>testBBean</ejb-name> <!--<destination-jndi-name>java:comp/resource/testAQ/Queues/ADAMSTESTQUEUE</destination-jndi-name>--> <!-- remote beans only --> <depends>jboss.j2ee:module=TESTA.jar,service=EjbModule</depends> </message-driven> </enterprise-beans> </jboss> <jboss> <enterprise-beans> <session> <ejb-name>testCBean</ejb-name> <!--<destination-jndi-name>java:comp/resource/testAQ/Queues/ADAMSTESTQUEUE</destination-jndi-name>--> <!-- remote beans only --> <depends>jboss.j2ee:module=TESTA.jar,service=EjbModule</depends> </session> </enterprise-beans> </jboss>
