Re: Does Tapestry (4) and Hibernate coexist nicely
Thx. I'm using Spring 2.0.6 and the OpenSessionInView Filter (for Hibernate) that comes with it - and have configured that in my web.xml. Doing some thorough testing currently... Yes, although it depends on how you implement it. You need to ensure that the session is closed by HiveMind in a threaded model, or problems will arise while rendering. I do it thusly: service-point id=HSessionManagerFactory interface=com.myasd.db.dao.ISessionManagerFactory create-instance class=com.myasd.db.dao.HibernateSessionManagerFactory/ /service-point service-point id=SessionManager interface=com.myasd.db.dao.ISessionManager invoke-factory model=threaded construct class=com.myasd.db.dao.HibernateSessionManager/ /invoke-factory /service-point All my DAO's are then done via invoke-factory: service-point id=AccountDAO interface=com.myasd.db.dao.proto.AccountDAO invoke-factory construct class=com.myasd.db.dao.impl.AccountDAO/ /invoke-factory /service-point I've been doing this in production for 6 months or longer and it's been working very, very well. Adding database operations to a Tapestry page is trivial after the setup.

RE: Does Tapestry (4) and Hibernate coexist nicely
I've had an application based on Tap 4.0.2, Hibernate 3.1, Spring 1.2.5, Acegi 1.0.0 with complicated inheritance and relationships, and Hibernate interceptors. I haven't touched the code in 10 months and it works like a charm. I ran into issues during development with Class cast exceptions for component parameters when accessing through OGNL, but just got around it by putting the accessors into Java code instead. This problem was not exclusive to lazy loading, but it did cause me to change to eager loading for a few relationships. Make sure you have a good equals() definition for your model classes - I added an oid property to a BaseModelObject populated from a UUID generator and used that for equality. I read a lot of different perspectives on equality testing for hibernate - and that's the religion I chose. All in all, lazy loading works very well. -Original Message- From: Jan Vissers [mailto:[EMAIL PROTECTED] Sent: Wednesday, August 29, 2007 8:41 PM To: users@tapestry.apache.org Subject: Does Tapestry (4) and Hibernate coexist nicely When it comes to lazy loading? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
