Spring 3 MVC Hello World Example

Getting stated with the Spring 3 MVC by developing first Hello World MVC example. This is the first example of writing first example in Spring MVC. After completing the tutorial you will be able to start developing small applications using Spring MVC.

In this section we will create a new project in Eclipse IDE and will name it "Spring MVC Hello World" application. We are using Spring 3 libraries in the application. You can download the latest Spring 3 framework from http://www.eclipse.org/downloads/.
