Subject Re: Missing ProductDerivation resource error
Date Mon, 08 Jan 2007 16:31:56 GMT
Thanks Michael,

I figured that last night after some digging around :-)

BTW, when I tried switching the 'openjpa.MetaDataFactory' to 'jdo' in 
'openjpa.xml' properties, I got a ClassNotFoundException for 'jdo'. I 
think the docs online say that 'jdo' is default meta data factory:
http://people.apache.org/~mprudhom/openjpa/site/openjpa-project/manual/ref_guide_conf_openjpa.html#openjpa.MetaDataFactory

But here it mentions only 'jpa' as the recognized built-in metadata 
factory:
http://people.apache.org/~mprudhom/openjpa/site/openjpa-project/manual/ref_guide_meta.html#ref_guide_meta_factory

Which is definitive? I have a .jdo mappings files that I'd like to 
process.

Cheers,

Rahul
