EntityManager injection on ServletContextListener not working with @Inject only @PersistenceContext
Hi,
I've created a simple test to show a problem I am having when trying to inject EntityManager objects on a ServletContextListener using CDI @Inject on JBoss 6.1 Final (or JBoss 6.0 Final):
@WebListener
public class ContextListenerTest implements ServletContextListener {
@Inject
Logger log;
@Inject
private EntityManager manager;
@PersistenceContext
private EntityManager ctxManager;
@Override
public void contextInitialized(ServletContextEvent sce) {
log.info("Context Initialized!");
log.info("Manager: " + manager); // This is null on JBoss 6.1 using JTA
log.info("ContextManager: " + ctxManager); // This is ok on JBoss 6.1 using JTA.
}
@Override
public void contextDestroyed(ServletContextEvent sce) {
}
}
Here is the output:
08:46:22,794 INFO [STDOUT] 394 INFO ContextListenerTest - Context Initialized! 08:46:22,795 INFO [STDOUT] 395 INFO ContextListenerTest - Manager: null 08:46:22,795 INFO [STDOUT] 395 INFO ContextListenerTest - ContextManager: org.jboss.jpa.tx.TransactionScopedEntityManager@103f52a
As the output shows using @Inject doesn't work on this context.
And if we do something like this:
public interface MyInterface {}
public class MyInterfaceImpl implements MyInterface {
@Inject
EntityManager manager; //Using @PersistenceContext would be ok here.
}
@WebListener
public class ContextListenerTest2 implements ServletContextListener {
@Inject
Logger log;
@Inject
private Instance<MyInterface> instances;
@Override
public void contextInitialized(ServletContextEvent sce) {
log.info("Context Initialized2!");
Iterator<MyInterface> it = instances.iterator();
log.info("Instances iterator: " + it + ", unSatisfied: " + instances.isUnsatisfied());
while (it.hasNext()) {
MyInterface impl = it.next();
log.info("Implementation: " + impl);
}
}
@Override
public void contextDestroyed(ServletContextEvent sce) {
}
}
The results are even worse:
09:15:18,211 INFO [STDOUT] 336 INFO view.ContextListenerTest2 - Context Initialized2! 09:15:18,211 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/projecttest]] Exception

Can anyone confirm if this is a bug or is there any configuration issues?
Follows the relevant part of persistence.xml
<persistence-unit name="bookmark-ds" transaction-type="RESOURCE_LOCAL"> <non-jta-data-source>java:/DefaultDS</non-jta-data-source> <class>domain.Bookmark</class> <properties> <property name="hibernate.show_sql" value="true" /> <property name="hibernate.format_sql" value="false" /> <property name="hibernate.hbm2ddl.auto" value="create-drop" /> <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup" /> </properties> </persistence-unit>
Thanks in advance,
