[Thomas Haskes <t.haskes@xxxxxxx>]

Did you try listing your entity classes in persistence xml?

To do that you need to add a "class" child to your persistnce xml before
the <properties> child like this.

<persistence-unit name="some_pu" transaction-type="RESOURCE_LOCAL">
		<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>

		<class>org.package.[...].DiscountCode</class>
		<class>org.package.SomeOtherClass</class>
		<properties>
			<property name="eclipselink.jdbc.driver" 				
value="oracle.jdbc.driver.OracleDriver" />
		[...]

I remember that when I switched to EL from Hibernate that I had to list
my classes as EL whas complaining about not knowing my entites. That
helped. EL seems to be more strict concerning unlisted entites as other
ORM's.

Later,
