Did you run the OpenJPA enhancer on your classes before running the
test, or, are you running in an environment that should be doing
automatic class processing (such as a Java EE application server)?
What do you get if you set the 'openjpa.Log' property to
'MetaData=TRACE'?

> Hi,

> adding OpenJPA as the provider provider, and 'drop and

> The test inserts a customer and 2 orders, then runs a JPQL

> The same example works correctly on Oracle. I used the
