Re: [S2] Where to put hibernate's SessionFactory?

What would happen if I wanted Yes, by definition, since application scope is shared accross all requests and sessions. For a Hibernate session factory that's probably what you want in most cases. more than one connection to databases (e.g: one for authorization and authentication, another for an e-shop)? The presumably you'd have a session factory configured for each connection; I'm not sure. How to handle connections to multiple databases is a Hibernate usage issue. Browse the Hibernate documentation and/or ask on their forums. L. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: [S2] Where to put hibernate's SessionFactory?
Thank you. I've implemented the non IoC version of it, which I found to be almost the same as in http://struts.apache.org/2.0.9/docs/non-ioc-version-of-opensessioninviewinterceptor.html http://struts.apache.org/2.0.9/docs/non-ioc-version-of-opensessioninviewinterceptor.html Antonio Petrelli-3 wrote: 2007/8/31, wild_oscar [EMAIL PROTECTED]: I am making my first web app and I found out today I was doing something wrong: I was building a SessionFactory on my HibernateEntityManager: _sessionFactory = configuration.buildSessionFactory(); This EntityManager is called on the action so, basically, I was creating a SessionFactory on each request.
