[jboss-jira] [JBoss JIRA] (WFLY-3137) logging errors in destroying a requestscoped entitymanager

[Stuart Douglas (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-3137?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12954437#comment-12954437 ] 

Stuart Douglas commented on WFLY-3137:
--------------------------------------

The entity manager is a container managed transaction scoped entity manager, calling close will result in an error. 

All you really need is: 

@PersistenceContext(unitName = mydatasource)
@Produces
@MyEm
private EntityManager em;

The EM is automatically closed at transaction commit/rollback time.

> I have a simple producer for a requestscoped entitymanager:
> @PersistenceContext(unitName = mydatasource)
> 	private EntityManager em;
> @Produces
> 	@myEM
> 	@RequestScoped
> 	protected EntityManager createEntityManager() {
> 		return em;
> 	}
> 	protected void closeEntityManager(
> 			@Disposes @myEM EntityManager entityManager) {
> 		if (entityManager.isOpen()) {
> 			entityManager.close();
> 		}
> 	}
> I inject this to applicationScoped bean. In the log, I see for each close of entityManager, wildfly logs an error:
> WELD-000019: Error destroying an instance org.jboss.as.jpa.container.TransactionScopedEntityManager at 7c213180 of Producer Method [EntityManager] with qualifiers [@myEM @Any] declared as [[BackedAnnotatedMethod] @Produces @myEM @RequestScoped protected createEntityManager()]
