Subject Re: Why would I choose OpenJPA over Hibernate?
Date Wed, 20 Feb 2008 14:17:21 GMT
Why I realize that Rick (and this list particularly) mainly looks for
pro-OpenJPA reasons here on the topic, I cant resist adding the reason why I
cannot use OpenJPA over Hibernate at the moment:

I simply cannot find or build any working example and/or configuration sample or
docs using weaving enabled OpenJPA in a Spring environment which would work both
running on a server and started without a container for unit tests.
