Subject Fwd: Cayenne and JPA?
Date Wed, 06 Feb 2008 18:27:28 GMT
LOL.  I mixed my lists, as this happened over on Tapestry, but here's  
the thread.  Looks like Cayenne might be an option depending on how  
far they're going, but it's not there yet, though I have done a bit of  
open-source work with Andrus (who heads that project) a long time ago,  
and he's good with quick support.

Anyway, I only mention it because it's an apache-based ORM which has  
been around for quite some time, and has a decent architecture, and a  
GUI mapping tool.  It's conceptually based on Enterprise Object  
Framework from NeXT, which became the core of WebObjects etc.  Good  
stuff, and the tool is convenient.
