Do you have problems with your own application or the bookstore example? Inside the main dbforms distribution are only the libs to compile dbforms - not to let run it. I think in your application are missing the batik classes which are used by jfreechart. You can get them from the jfreechart distribution or just from the bookstore example....
See documentation of jfreechart, cewolf and jasperreports of dependend libs. Or just copy the whole bookstore stuff!
