ADF Best Practice : About user session management in ADF BC

Question

Hi,
I'm using ADF BC and I want to manage information specific to a particular user.
In the developer's guide at §9.10 it is advised to use APIs relative to DBTransaction class through the getSession and getUserData methods.
I have several questions :
* are Session objects returned by ApplicationModuleImpl.getSession() and DBTransaction.getSession() the same ?
* is it safe to manage user information by using the map returned by the oracle.adf.share.ADFContext.getSessionScope() method ?
* finally, which is the recommended approach and what are the caveats of each ?
Thanks a lot,
Seb.

Here is the code fragment :
   * Return the jhsUser object.
   * For this method to return an object, the user object must have called setUser
   * on the application module
  public Object getUser()
    Object user = ADFContext.getCurrent().getSessionScope().get(JhsUser.JHS_USER_KEY);
    if (user!=null)
      return user;
    // code below for backwards compatibility
    if (getSession()==null)
      return null;
    return getSession().getUserData().get(JhsUser.JHS_USER_KEY);
   * Stores user object as am session userdata.
   * @deprecated user is now retrieved using pull meachnism with ADFContext, instead of
   * push.
  public void setUser(Object user)
    getSession().getUserData().put(JhsUser.JHS_USER_KEY, user);
  }Notice the deprecated method setUser.
