This is my persistence.xml. I get this message in the log when I try to save the record.
Caused by: java.lang.IllegalStateException:
Exception Description: Cannot use an EntityTransaction while using JTA.

In another class method I have a method that contains the entity manager code:
try {
em.getTransaction().begin();
em.merge(classname); //
em.flush();
em.getTransaction().commit();
} finally {
em.close();
}
}
I tried commenting out the begin, commit and flush so to use JTA instead of Resource local Entity Manager. But that just results in no error messages the merge does not save any changes to the database
