Can a WAR depend on a JNDI entry in JBoss 5.1?

henrik242 Mar 29, 2010 4:10 AM

Hi.

As part of an upgrade from JBoss 4.0.4 to 5.1, I am trying to get a WAR to deploy after an EAR is successfully deployed.  [JBoss 5.x does not support PrefixDeploymentSorter|http://community.jboss.org/message/201628#201628] like 4.x did, which means that I have to use "depends" in the WAR's jboss-web.xml.
 
 
It seems I [cannot depend on the EAR itself|https://jira.jboss.org/jira/browse/JBAS-3654?focusedCommentId=12343310#action_12343310], so I pick the last deployed EJB instead.  This EJB provides a JNDI entry that the WAR needs.
 
Here's the EJB as it deploys when the WAR is absent from the deploy directory:
{code}
2010-03-25 10:47:30,348 INFO  [org.jboss.ejb3.session.SessionSpecContainer] (main) Starting jboss.j2ee:ear=my-ear.ear,jar=mypackage-ejb.jar,name=MyFacadeBean,service=EJB3
2010-03-25 10:47:30,350 INFO  [org.jboss.ejb3.EJBContainer] (main) STARTED EJB: my.package.MyFacadeBean ejbName: MyFacadeBean
2010-03-25 10:47:30,371 INFO  [org.jboss.ejb3.proxy.impl.jndiregistrar.JndiSessionRegistrarBase] (main) Binding the following Entries in Global JNDI:
    
      my/MyFacade/local - EJB3.x Default Local Business Interface
      my-ear/MyFacadeBean/local-my.package.MyFacade - EJB3.x Local Business Interface
{code}
 
And here's the depends snippet from jboss-web.xml:
{code}
<depends>jboss.j2ee:ear=my-ear.ear,jar=mypackage-ejb.jar,name=MyFacadeBean,service=EJB3</depends>
{code}
My problem is:  The WAR starts to deploy immediately after "STARTED EJB:", i.e. before MyFacadeBean is bound to JNDI, which causes bean deployments to fail:
{code}
2010-03-25 10:47:39,068 ERROR [my.facade.FacadeFactory] (main) MyFacade not bound
2010-03-25 10:47:39,069 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[my.host.no].[/]] (main) StandardWrapper.Throwable

[...]
Caused by: java.lang.RuntimeException: javax.naming.NameNotFoundException: MyFacade not bound
      at my.facade.FacadeFactory.getFacade(FacadeFactory.java:61)
{code}
After the WAR has finished its deployment, MyFacade happily (mockingly?) continues its deployment and binds the JNDI entries.
 
If I hot-deploy the WAR after the EAR has deployed, everything works as intended.
 
I even thought of depending on a dummy EJB in the EAR, and using module-order: strict in  jboss-app.xml to force it to load as the last module.  But alas, [JBoss 5.x does not support that|https://jira.jboss.org/jira/browse/JBAS-7106] either.  Doh!
 
Is there a way to depend on the JNDI entry itself?  Are there other ways of solving this?

Can you please post the entire exception stacktrace and the contents of jboss-web.xml?

Sure. Here's the stacktrace:
