Subject RE: Using Torque to generate value class/JavaBeans
Date Wed, 01 Oct 2003 22:15:26 GMT
If you already have your torque schema you can use the ojb Ant target.

ant -f build-torque.xml ojb

and you'll find in /src/ojb the value classes for your Torque schema along
the descriptors to use for the ojb runtime, go and just grab your VOs
