Lars,
Table and field mapping via xml is not done in the persitence.xml. It is
only done as part of an orm.xml file. Any defined orm.xml files that you
wish to use need to be specified in your persistence.xml using the
<mapping-file> element. But, the actual mapping is done in your orm.xmlfile.
So, if you have a file named orm.xml, your persistence.xml would have
something like this:
<persistence-unit name="mypu">
:
<mapping-file>META-INF/orm.xml</mapping-file>
:
</persistence-unit>
Is this what you were asking about?
Thanks,
Kevin
