Null pointer exception while accessing lightadmin url.

[tilhari95]

I have followed the given documentation and trying to integrate lightadmin in my web application. Following error is coming everytime I access /admin url for lightadmin dashboard when using spring version 4.0.4, but with spring 3.2.4 version and corresponding light admin jar the lightadmin is working fine. Also there is need to scale the product for newer version of Spring.

Looks like there is some compatibility problem with Spring 4 !!
This tool is really helpful.
I need suggestions to make it work..!!
