>So why does OpenJPA fail on registering Entities?
The problem is that when you don't list your entities, OpenJPA doesn't know
that the alias 'DP_PLZ_DA' is an Entity until the x.y.z.DP_PLZ_DA class is
loaded. If you were to look at an enhanced Entity you would see that OpenJPA
adds a static initializer that will register each Entity with OpenJPA.
An alternative to calling "new DP_PLZ_DA();" would be to add something like
this to each of your testcases.
// List each Entity that this test is going to use.
private Class[] _entities = new
Class[]{x.y.z.DP_PLZ_DA.class,x.y.z.DP_PLZ_DB.class,etc... };
