I'm brand new to Tapestry. I have a large application that uses Spring to configure the Hibernate SessionFactory. I have a request interceptor defined in Spring so that I can bind a Hibernate session to each request's thread. Closure of the session is deferred until the request returns, to prevent LazyLoadingExceptions (OpenSessionInViewInterceptor)
I need to apply the same hibernate-session-per-reqeust feature to the new Tapestry code I'm writing, which will only be a small part of a much bigger system. My ideas are: a - Call Tapestry's filter methods from a custom Spring controller, then assign interceptors to the controller. This isn't working because the controller needs to be mapped to some URL pattern in web.xml (either like "/tap/*" or "*.tap"). It seems like Tapestry's filter doesn't like to be mapped to anything other than "/*". I need to keep the tapestry requests separate from all the other servlet mappings for now. I successfully mapped the controller to "/tap/*", which activated the interceptor, but then tapestry choked handling the real request. b - Change the OpenSessionInViewInterceptor to an OpenSessionInViewFilter. This would work if I declared the filter before the Tapestry filter in web.xml. But, some of my Spring servlets don't need this database connection, so I would be opening and closing the session unnecessarily. c - Use the Tapestry-Hibernate module and have Tapestry configure Hibernate independently from Spring. This is annoying because I'll have to move all my Hibernate configuration out of the spring XML it's in, and into a separate file. Plus, I'll have two complete SessionFactory instances when I really only needed one. d - I tried looking into the dispatcher classes but there's no "afterReturn()" method, only dispatch(). So I have no way to close the session/connection after the request returns. Suggestions would be much appreciated! -- View this message in context: http://www.nabble.com/T5---Spring---Hibernate-Lazy-Loading-tf4685218.html#a13388806 Sent from the Tapestry - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
