Hi, Somebody knows a simple example of OJB application that has supported mapping N:N? It would be possible to divulge for us?
In attach it is our example based on tutorial 3 that have problems. In the class UCEnterNewRole, we use class/object intermediate (role) and only this object is store in the DB, but the others not. In the class UCEnterNewRole1, we don't use class/object intermediate and then only this is not store. Somebody can help us? Thanks, Alex / Tiago _______________________________________________________________________ Yahoo!
