Hi all,
im new to hibernate & spring. Im using it in my project.
i use HibernateTemplate.update() to update the data base. I need to audit log the same.
My Problem :
How do i get OldValues[] or oldState of the object.
1. I tried through an interceptor extending EmptyInterceptor, the interceptor was invoked but still the oldValues[] are null.

2.I also tried it with PreUpdateEventListener. the ListenerEvent was invoked. But still event.getOldState() is returning null.

Can somebody help me how to obtain oldValues[] or oldState while using
HibernateTemplate.update() ?

Thanks in Advance...

Oldvalue handling isn't an Hibernate feature.

You can use PropertyChangeListener (http://java.sun.com/docs/books/tutorial ... index.html) to follow the value changing and retreive old value.

Bye.

I want spring to retrive the old values from the database before it updates a row.

My Interceptor which extends an EmptyInterceptor does give the old values when HibernateTemplate.merge(obj) is called. where as HibernateTemplate.update(obj) doent give me oldValues[]. Its always null inside the inteceptor.


getHibernateTemplate.merge(obj) is expensive.
So i need to replace it with getHibernateTemplate.update(obj).

But when i use update i face the above mentioned problem.

Can SomeBody help me...
