I'm not sure if your orm.xml file is invalid or not
but one of the ways I've found to get a start on a
valid orm.xml file when I wasn't sure if mine was
correct was to use the Reverse Mapping tool in openjpa
(see the manual for more info).
If you already have a working example using
annotations, you can use the ant task to create your
orm.xml file for you, based on what you already have
in the database from your previous working example.
I do know that my orm.xml files look very different
from yours but I don't know where exactly the problem
might be.
