MongoDB Persistence via EclipseLink NoSql JBoss AS 7.1.1.Final

Question

I am trying to use EclipseLink NoSql Persistence for MongoDB in JBoss AS 7.1.1.Final.

I am trying to use the EntityManager like:

    EntityManager em = Persistence.createEntityManagerFactory("mongo")
            .createEntityManager();

    Model m = new Model();
    em.getTransaction().begin();
    em.persist(m);
    em.getTransaction().commit();

Here is my persistence.xml

<?xml version="1.0" encoding="UTF-8" ?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="1.0">
    <persistence-unit name="mongo" transaction-type="RESOURCE_LOCAL">
        <class>com.Model</class>
        <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
        <properties>
        <property name="eclipselink.ddl-generation" value="dorop-and=create=tables" />
            <property name="eclipselink.target-database"
                value="org.eclipse.persistence.nosql.adapters.mongo.MongoPlatform" />
            <property name="eclipselink.nosql.connection-spec"
                value="org.eclipse.persistence.nosql.adapters.mongo.MongoConnectionSpec" />
            <property name="eclipselink.logging.level" value="FINEST" />

        </properties>
    </persistence-unit>
</persistence>

I added the EclipseLink module to my JBoss install using the instructions specified here. I also added javax.resource.jar as a dependency in the EclipseLink modules.xml and created a JBoss module for javax.resource. If there is any way to avoid having to add the module to JBoss, and instead put it in my war, then please let me know.

Here is the current problems I am facing, which is weird because I know it is loading the javax.resource.jar (I got a different error before without it) and the missing javax.resource.cci.ConnectionFactory class is in there.

Recently added to persistence.xml and added eclipselink.jar to JBoss modules - roadblock updated. — Bob B, Jul 14 '12 at 02:33
The error is because the ResourceException class cannot be found when loading a class. This is because EclipseLink is trying to load the "MongoPlatform" class using the application classloader and then is getting an exception when using it to create a new instance. Unfortunately the missing ResourceException class means the actual exception cannot be thrown. Try making sure the javax.resource is added as an EclipseLink module dependency — Chris, Jul 16 '12 at 16:32
@Chris - Man... I did that last week but I botched the modules.xml for javax/resource. Updated roadblock and added step. Thanks! — Bob B, Jul 16 '12 at 16:53

Had the same issuse. Please add "< module name="javax.resource.api" />" to the dependencies in the module.xml of org.eclipse.persistence.

It worked for me.
