Subject Re: Trouble with persistent element (extended schema) when field name does not match column name
Date Thu, 01 May 2014 16:19:16 GMT
Have you tried turning on trace?  The simple column name mapping is part of
the spec, so that should work regardless.  Applying the externalizer is an
OpenJPA extension to the orm.xml, but it doesn't even seem like you are
getting that far.  Maybe the trace will help show where the processing is
going awry...  Good luck!
