Debug level Hibernate log excerpt:

AuditInfoType example from page 48.html page in web site does not work in Hibernate 3 because of deepcopy method: Hibernate.TIMESTAMP.deepcopy does not have this signature in this release.
Any solution?

Hi, did you find a solution for this problem?

The signature of deepcopy is really "exotic" for newbies.. :(

Here I send you my actual method.

It works for me.

I have translated variable names from Spanish into English in this example. if you see any variable that is not ok it is because of the translation...

There are two commented lines that correspond to the previous release 2 lines.
As you can see, there is no need to deepCopy them because casted value object already solves the problem.

Anyway, I have all this audit interceptor classes working as expected since Hibernate release 2. I do not mind giving you some words of advice if needed.
