Re: [appfuse-user] lazy loading impossible to set up

Matt Raible-3
You should be able to use the following in your DAOTest and
ManagerTest classes to keep the session open when running your tests:

protected void setUp() throws Exception {
    // the following is necessary for lazy loading
    sf = (SessionFactory) ctx.getBean("sessionFactory");
    // open and bind the session for this test thread.
    Session s = sf.openSession();
          .bindResource(sf, new SessionHolder(s));
    // setup code here

protected void tearDown() throws Exception {
    // unbind and close the session.
    SessionHolder holder = (SessionHolder)
    Session s = holder.getSession();
    SessionFactoryUtils.closeSessionIfNecessary(s, sf);

    // teardown code here
