Subject Re: Missing ProductDerivation resource error
Date Mon, 08 Jan 2007 16:49:56 GMT
Unfortunately you can't use JDO with OpenJPA, so you'll have to convert your
jdo mappings files to persistence.xml.

OpenJPA and BEA's Kodo share much of the same code, with one of the
differences being that Kodo supports JDO as well as JPA.  The references to
JDO in the OpenJPA documentation were missed when some of the documentation
was generated.

Sorry for the confusion, but at this time there OpenJPA doesn't included a
JDO interface.
