Hi,

I am using EclipseLink 2.5.0 in an rcp. The entity beans have an EntityListener annotated:

@MappedSuperclass

@EntityListeners(EntityMediator.class)
@ObjectTypeConverter(name = "booleanConverter", dataType = java.lang.Short.class, objectType = java.lang.Boolean.class, conversionValues = {
		@ConversionValue(dataValue = "0", objectValue = "false"),
		@ConversionValue(dataValue = "1", objectValue = "true") }, defaultObjectValue = "false")
public abstract class AbstractEntity implements Entity


I instantiate the PersistenceProvider manually and obtain from it the EntityManagerFactories. Starting my app there is an exception thrown when the tries to find an entity:

	@Override
	public T find(final Long id)
	{
		T entity = null;
		EntityManager entityManager = null;
		try
		{
			entityManager = this.connectionService.getEntityManager();
			if (entityManager != null)
			{
				entity = entityManager.find(this.getEntityClass(), id);
			}
		}
		catch (Exception e)
		{
		}
		return entity;
	}


The exception in question starts with the message:
[EL Finest]: jpa: 2013-07-19 08:09:57.639--ServerSession(568888)--Thread(Thread[Start Level Event Dispatcher,5,main])--javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file:  java.naming.factory.initial


What's going wrong here? Any hint is appreciated!

The full stacktrace is:
