I am getting a Caused by: org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: gov.michigan.mdch.ibs.domain.Users.userRoleses, no session or session was closed.

I am using JQUERY for my Ajax to call the controller. The Controler will pass back a JSON object to be render in a div tag on the JSP
I know the user bean I am trying to return has 2 children tables. I have included the user bean and the DAO. I have tried the OpenSessionInViewFilter in the web.xml and that is not working. I just wanted to know if you had any ideas.

You could try to use interceptors instead of filters. Anyway, the OpenSessionInViewFilter should work fine.

Did you do a filter mapping after defining the filter on the web.xml?

You can find an example of a web.xml file and you can also download a little sample project that uses OpenSessionInViewFilter here:

Good luck!
I agree. Here's the link:
