Addition of Two Numbers Using Spring Framework

I am very new in Java Enterprise Edition or J2EE programming particularly using Spring Framework. But I find it easy to learn once you have known the basic concepts and principles behind it. I am thankful that there is a video tutorial in YouTube that we can study to be specific the tutorial of Ankush Gorav here his website http://www.gontu.org.

I have learned a lot from his tutorial in YouTube. In gives me an idea how to get started this sample program that I wrote is based on his tutorial will ask the user to give two numbers and then our program will find the total sum of the two numbers.
