I have overrode the doFilterInternal method of the OpenSessionInViewFilter and got to working, but I don't think I need to this but I had to, to move forward. Here is the code (The file attachment didn't work for me).
Code:

After i used this filter its working but the control still goes twice in to this filter per request.
I hope somebody can tell me what is going wrong with my upgrade.
Thanks
