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