MDB in separate jar fails over persistence.xml

kevintee Mar 7, 2011 5:36 PM

Hello,

My application contains two separate jars: 1. Entity Jar with persistence.xml 2. MDB ( shown below)

ear
 |-- entities-ejb 
 | |-- META-INF
 | | |-- persistence.xml ( defines 'testPU')
 |
 |-- myMessagingEJB3.jar
 | |-- MyMessageDrivenBean
 |
 |-- war

We are in a process of migrating our application to JBOSS 5.1. As suggested, we changed the Annotation class package from org.jboss.annotation to org.jboss.ejb3.annotation (impacting SecurityDomain and ResourceAdapter). Now we are seeing the MDB causing deployment failure. Failure indicates the MDB expecting persistence.xml whihc it should not require.

Here is the exception trace:

ANy helps will be much appreciated.

1. Re: MDB in separate jar fails over persistence.xml

The JPATestDAO seems to be injecting @PersistenceContext from a different jar. What does that code look like? Since the PU belongs to a different jar, it should be:

@PersistenceContext(unitName="entities-ejb#testPU")

By the way, on a different note, if it's an option then use JBoss AS 6.0.0.Final instead of JBoss AS 5.1.0.

2. MDB in separate jar fails over persistence.xml

kevintee Mar 8, 2011 1:28 PM (in response to jaikiran)

Thanks JaiKiran for the reply. Unfortunately, considering 6.0 is not a possibility in the immediate future.

The intriguing part is: JPATestDAO is actually part of entities-ejb and not

myMessagingEJB3.jar but somehow JBOSS 'thinks' JPATestDAO is in myMessagingEJB3.jar.

"16:29:00,766 ERROR [Ejb3Deployment] Exception while processing container metadata for EJB: JPATestDAO in unit: myMessagingEJB3.jar"

Because it's part of entities-ejb itself, I have the PersistenceContext defined without the jar qualifier:

@Statelesspublic class JPATestDAO implements ITestDAO {
    @PersistenceContext(unitName="testPU")
    private EntityManager em;

Like you suggested, I changed the JPATestDAO so that now it has jar qualifier in @persistenceContext. Now JBOSS identifies the DAO to the right jar but I get an error indicating "EJB3 failed to resolve persistence unit entities-ejb#testPU" with an underlying error being "Can't find a deployment unit named entities-ejb". However, I do see the entities-ejb jar underneath the ear folder JBOSS builds.
