JBoss AS7 cannot find my persistence.xml

[kc7bfi]

EntityManagerFactory emf = Persistence.createEntityManagerFactory("TravelTimeEngine-DS");I am deploying a SAR file that contains a META-INF directory with a persistence.xml file. When the SAR deploys it finds the persistence.xml file and creates the persistemce unit

20:56:00,582 INFO  [org.hibernate.ejb.Ejb3Configuration] (MSC service thread 1-4) HHH000204: Processing PersistenceUnitInfo [

    name: TravelTimeEngine-DS

    ...]

However, when I go to get the persistence unit I get the following error

20:56:08,102 INFO  [org.hibernate.ejb.Ejb3Configuration] (InirxCommunications-2) HHH000318: Could not find any META-INF/persistence.xml file in the classpath

20:56:08,102 WARN  [com.orci.TravelTimeEngine.hibernate.utils.ThreadTransaction] (InirxCommunications-2) getSessionSafe: javax.persistence.PersistenceException: No Persistence provider for EntityManager named TravelTimeEngine-DS

20:56:08,102 ERROR [stderr] (InirxCommunications-2) javax.persistence.PersistenceException: No Persistence provider for EntityManager named TravelTimeEngine-DS

20:56:08,102 ERROR [stderr] (InirxCommunications-2)     at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:69)

This is how I am getting the persistence unit:

EntityManagerFactory emf = Persistence.createEntityManagerFactory("TravelTimeEngine-DS");

Any idea what I might be doing wrong? Why it first finds the persistence.xml file but then fails to find it on the classpath?

Thanks, David

DS souns like ur passing datasource name. EMF takes persistence unit name.

Are you bundling the JPA impl with your app?

[kc7bfi]

Yes I am. It seems that having the persistence.xml in the META-INF directory of the SAR is not sufficient. I also have to have it in the JAR that contains the class that I am calling the createEntityManagerFactory() method. Not sure why this is the case. It seems that the SAR is not in the classpath so it cannot find the persistence.xml that is in the SARs META-INF directory.

So you have strucutre like this?

my.sar

* lib

** my.jar

** <some-jpa-impl>.jar

* META-INF

** persistence.xml

Bundled JPA impl has issues, as I'm having similar issues when bundling DataNucleus impl as part of my .war.

I patched AS7 a bit to get around the issue: https://github.com/alesj/jboss-as/commit/278800e24f82c704fec0be14d7d7d2c956880600

(this is a custom branch, but the hack/workaround might give you some ideas)

[kc7bfi]

Close, but it is

my.sar

* my.jar

* some-jpa-impl.ja

* META-INF

** persistence.xml

In my SARs the jars are in the root and not under the lib directory. This is how I've done it under as5, should it be different in as7?

[alesj]

No, it (the structure) used to be different for AS4, hence I thought you still use that .sar notion

(as it was originally a simpler way to deploy custom services, but we simplified that with MC).

But yeah, my guess would be you're having the same problem as me -- that PPResolverImpl doesn't understand / know your PP.

e.g. your PP is found as part of services/ search, but the AS7' PPresolver instance used in javax.persistence.Persistence doesn't know it

This definitely needs fixing, the question is just how soon. ;-)

Ales, is there an JIRA issue for that error - javax.persistence.PersistenceException: No Persistence provider for EntityManager ? I heard from a seam user the same about the same experience with Web application (WAR).
