Hi everyone

I'm struggling with setting up my application in order to package a custom PersistenceProvider:

According to the documentation, the only thing required is to have the property providerMoule set to 'application'. And within the provider-tag, I set the fully qualified name of my custom PersistenceProvider.

So my persistence.xml basically looks like:

<persistence>

    <persistence-unit>

          <class>org.url.my.TestEntity</class>

          <provider>org.url.my.CustomPersistenceProvider</provider>

          <jta-data-source>java:/jdbc/myappy</jta-data-source>

            <properties>

                <property name="jboss.as.jpa.providerModule" value="application"></property>

            </properties>

    </persistence-unit>

</persistence>

At first everything seems to be fine, tables are correctly created and server is starting. However, it is not possible to insert any data with the EntityManager injected with @PersistenceContext. Trying to insert data does NOT throw an exception, it simply does not happen.

Strangely I have the exact same behavior, if I set the provider to org.eclipse.persistence.jpa.PersistenceProvider and package the EclipseLink jars withing the application. Also, creating a custom module on Wildfly, containing my custom PersistenceProvider does not work.

It only works, if I install the EclipseLink jars as a module on Wildfly and working with the default PersistenceProvider...

Does anybody know what I'm missing or has some experience with custom PersistenceProviders?

Cheers
