jboss.entity.manager.factory.jndi.name is used if you want to expose your persistence unit to JNDI. Don't use it if you don't want to expose it to JNDI.

cheers,

Hi,

I thought that jboss.entity.manager.factory.jndi.name was required in order to be catched in components.xml by the tag persistence:managed-persistence-context with the attribute persistence-unit-jndi-name and make the persistence context managed by Seam... :-/

So, if I don't use it I could use @In in PersistenceContext?

Thanks

I use Seam managed Persisten Context and I refer jndi contexts in both the places

persistence.xml

<property name="jboss.entity.manager.factory.jndi.name" value="java:/EntityManagerFactories/myDatasource"/>

components.xml

<persistence:managed-persistence-context name="entityManager" persistence-unit-jndi name="java:/EntityManagerFactories/myDatasource" />

I dont think you can avoid this.

Yes, I think so.

I tried in components.xml with

<persistence:entity-manager-factory name="intranet-commons-emf" persistence-unit-name="intranet-commons-pu" auto-create="true" />
<persistence:managed-persistence-context name="iem"  entity-manager-factory="intranet-commons-emf" auto-create="true" />

in order to try to create a managed persistence context without JNDI btu without success. I obtain the next exception:

If I must use JNDI then... what happens if two applications share the same JNDI entity manager name? the application crash on deploy?

Thanks!

5. Re: Seam-managed persistence context with JPA

mmartin Jun 5, 2008 3:16 PM (in response to mmartin)

I get a mistake in last post. I tried with

<persistence:entity-manager-factory name="intranet-commons-emf" persistence-unit-name="intranet-commons-pu" auto-create="true" />
<persistence:managed-persistence-context name="iem"  entity-manager-factory="#{intranet-commons-emf}" auto-create="true" />

but still without success.

The problem is that I want to make a JAR with some entities, EJB3 and seam components. All packaged with its own persistence.xml.

The problem is not the declaration in components.xml which could depends of each application. The problem is with persistence.xml of the JAR library. If I add jboss.entity.manager.factory.jndi.name all applications that uses the library are going to try to put in the seam JNDI name their persistence unit.

Any idea to workarround this?

Thanks!
