Hibernate initialization
I am attempting to use hibernate in a tapestry-based application. I
would like to carry out hibernate related initialization *before* the
very first html (home) page appears, i.e., I want the following to
happen before the the user sees the first page of the application.
Configuration cfg = new Configuration();
cfg.addClass(com.cgc.esd.pages.csys.User.class)
.addClass(com.cgc.esd.pages.csys.Application.class)
.addClass(com.cgc.esd.pages.csys.Actor.class)
.addClass(com.cgc.esd.pages.csys.Usecase.class)
.addClass(com.cgc.esd.pages.csys.Role.class)
.addClass(com.cgc.esd.pages.csys.Responsibility.class)
.addClass(com.cgc.esd.pages.cinv.Buyer.class)
.addClass(com.cgc.esd.pages.cinv.BuyerCompositeID.class)
;
Properties properties=new Properties();
properties.load(HUtil.class.
getResourceAsStream("/hibernate.properties"));
cfg.setProperties(properties);
sessionFactory=cfg.buildSessionFactory();
The first page is the login page. Right now, the initialization happens
in the visit.authenicate() method that the login page's listener method
invokes to validate a user's credentials using the user's profile stored
in a db table. If the login is successful, the user sees the "main"
page. The problem is that there is a delay in the login and the
appearence of the main page because of all the hibernate initialization
happening the very first time. This needs to be done only once. Is there
an engine method akin to servlet's init method where I can do such one
time initialization? What is a good place to do this?
Thanks

Put the initializations in the Global's constructor.

This is what application extensions are for. You could wrap this code up as a JavaBean and add an
<extension> to your application specification. There's an attribute to force the creation of the
bean at application initialization.
