Hello,

I have to use the mecanism of session in my "facade" design pattern, but I do not realy understand how to do.

I use the Facade, Service, DAO system.
Do you know where find a easy sample about this.
Maybe the class in the title can be used ?

Could you explain what you want to do? What mechanism do you mean? Can you post an example?

In fact, I have to do some action like :
- Get object from the data base
- Save object in the data base

Currently in my DAO implementation object I have this method :

Code:

public boolean update(Object dossier) {
      Session session = HibernateUtil.getSession();
      Transaction transaction = session.beginTransaction();
      session.saveOrUpdate(dossier);
      transaction.commit();
      session.close();
      return true;
   }

But it was said to me that I need to manage the transaction in highter level.
Because a save of one object can need to save others object in the future and I need to be sure that my transaction is arround all the operation to do...

So, you're using Spring.

Take a look at the following free for download book which describes declarative transaction boundaries with Spring.

Also, take a look at the Spring reference on transactions:
