Re: Improving the OFBiz User Interface with JPA

[James Yong <ja...@apache.org>]

Hi Markus,

I have checked out the contents of the jar file and the entity beans look comprehensive. 

If you are still working on this, can you provide a minimum patch to OFBiz trunk version so that we can test them out in stages. 

Personally, I am in favor of adopting JPA and agree it will be good for OFBiz.

Regards,
James Yong
