Hello there,
I am trying to reverse engineering database and I had put in the ReverseEngineeringStrategy class. I had this problem of classloader cannot locate my hibernate libraries file.
I had done my very best to test using different method to validate the existing of classpath but still fail. Please help me out. I had includes the following code blocks. TQ
--------------------------------------------------------------------------------
Hibernate version: 3.1.0, Hibernate Tools version: 3.1.0 beta1

1. Ant task build.xml
Code:

The target I need to run is "reversedb".
