Subject Re: Using Cayenne with RCP and Birt?
Date Wed, 26 Nov 2008 16:18:32 GMT
I've already launched into learning about ODAs for my app, so I'll  
definitely keep in touch and contribute back if all goes well. I've  
been pushing Cayenne hard and resisting the "it must use Hibernate"  
mandate from a couple of companies that I'm working with, and frankly  
I think that integrating the BIRT framework into their RCP  
applications so they get canned reports AND the ability to compose  
their own custom reporting will just amaze.

Kind regards,

Lawrence Gerstley, Ph.D.
