JBPM 6.3.0

Wildfly 8.1.0 Standalone

I hope someone out there can help me out. I have been tearing my hair out for a few days now on this one...

I am writing a jbpm console and want to get a list of tasks assigned to a user. Once I have the task service I will be off and running but I am getting the error below when running the code to create the EntityManagerFactory. All deploys fine and I see the hibernate introspection of JBPM tables (if I had the JNDI name wrong this wouldn't work, right ?).

- I have the Datasource configured in Wildfly as can be seen in Standalone.xml and the Wildfly admin console

- I have the Datasource referenced in Persistence.xml

- Do I need to do something else ?

Any help very much appreciated.

Thanks

Snippets below:

Code...

public TaskService getTaskService() {

org.kie.api.runtime.manager.RuntimeEnvironmentBuilder builder = RuntimeEnvironmentBuilder.Factory.get().newDefaultBuilder().entityManagerFactory(Persistence.createEntityManagerFactory("com.mypackage.persistence.jpa")).persistence(true);

RuntimeManagerFactory mf = RuntimeManagerFactory.Factory.get();

RuntimeManager runtimeManager = mf.newSingletonRuntimeManager(builder.get());

return runtimeManager.getRuntimeEngine(EmptyContext.get()).getTaskService();

}

Persistence.xml...

...
