Using OpenSessionInViewFilter in Spring-Hib-Wicket

[H Melua]

Hello

I'm having a problem with the lazy loading exception...

org.hibernate.LazyInitializationException: could not initialize proxy - no Session
 

Why does this happen? because i load some data and view it in a page, and here the session transaction ends... and when i try to delete one of the listed items i get the error as the session no longer exists...

the hibernate documentation recommended using OpenSessionInViewFilter to overcome this problem, but i found it too complicated to figure out exactly how to do it

I'm using applicationContext.xml where all my hibernate+spring wiring goes to..

what do i need to change in my xml file in order to make these session open as long as possible?

Thanks

Do you ever figured this out? There is a good explanation in the Manning book called 'Wicket in Action'.

Thanks Steve

I figured out my mistake... I was trying to cache a service object that shouldn't be cached since it is used by all other pages...
