Felix,
So how is the EJB subsystem going to know which class to return if I don't use
a discriminator column?
I tried removing the discriminator as you suggested, knowing it would not work,
and as I thought it did not work. I get the error below with no discriminator
column in any of the classes. I previously only declared the discriminator
column on the base class and used @DescriminatorValue in the subclasses. That
is how I cofigured when I started this thread/post.
Error returned:
Could not find a setter for property connected in class
com.tester.server.FMPUnit
Partial stack trace:

FYI: This is a different app so the class names don't match my original post.
