Hi there. I need a solution to the following problem. Cause of business rules I need to track every change to the database in a seperate log. I had a look at some posts and now I think I could use an Interceptor where a add the functionality to the findDirty method. I also thougt of using an JPA EntityListener but there I dont have access to the previous state, right ? What do you think is the most straightforward solution to this problem ? Any hints are appreciated ! Thanks Tom
