[jboss-user] [JBoss Seam] - how to trace failed entityManager injection?

[gsegura]

I'm using seam 1.1.5GA, and create a project with seam-gen. The authenticator component is generated automatically.
just filled the sql script (-dev.sql) to populate the database and when trying to test the login page this exception is thrown:

org.jboss.seam.RequiredException: In attribute requires value for component: authenticator.entityManager

The relevant part of Authenticator.java is:
@In EntityManager entityManager ;

I have the same name in components.xml (all generated by seam-gen):
<core:managed-persistence-context name="entityManager" persistence-unit-jndi-name="java:/hermes2EntityManagerFactory"/>

Also I checked with jndi viewer and the datasource and entityManagerFactory were published successfuly:
Java: Namespace
  |   +- hermes2EntityManagerFactory (class: org.jboss.ejb3.entity.InjectedEntityManagerFactory)
  |   +- hermes2Datasource (class: javax.sql.DataSource)


No other exception before that one. Just little before, the console showed some unrelated  (I think) errors , all identical to this one:
00:05:25,656 ERROR [STDERR] 8/02/2007 12:05:25 AM com.sun.facelets.compiler.TagLibraryConfig loadImplicit

Finally, I include some lines from server.log which made me think everything was ok (except the last one :P ):

  | 

Excuse such a verbose post but I just don't have any clue.

how could I check why is failing the entityManager injection??
