Thanks for this clarification Van.
I would just like to add an observation that I made when looking into
session management; there is another means by which hibernate sessions are
cleaned up in Mifos.
Struts action classes in mifos extend
org.mifos.framework.struts.action.BaseAction, which contains the method
postExecute(). This method is called after every struts action, and will
close the hibernate session if the calling method is annotated with the
org.mifos.framework.util.helpers.CloseSession interface... example from
SavingsAction below:
@CloseSession
@TransactionDemarcate(validateAndResetToken = true)
public ActionForward create(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
// stuff ...
}
