Subject RE: Use Jakarta's ObjectRelationalBridge (OJB) for your Struts ap p'spersistence layer
Date Thu, 20 Jun 2002 21:25:24 GMT
Just one more to throw out there.  Solid design.  Has a good modeling tool
to create or reverse engineer a relational database.  Plus it generates java
source.

http://objectstyle.org/cayenne/ 

I just started using it a week or so ago.  Extremely happy so far.  Requires
the J2SE 1.4 tho...that may be a problem for some.
