Suppose we want to have valid a user id or a session id with each in coming request. Instead of retrieving this attribute from request or session object, we receive as a url variable. Let us see how this works.

In this post, I am going to give you a start up code base for a Spring MVC 3 based application. If you want to go back and refer to the previous version of Spring MVC then this article will help you. I am assuming that the reader is already aware of Java 5 and Spring basic concepts like annotations, dependency injection etc. Spring 3.0 has extensively used the popular annotation feature of Java 5. As we move ahead in this article, I’ll mention more new things wherever applicable.

If we look at the way Java open source technologies are advancing around plain old Java objects, we can definitely say that this is an era of POJOs. Now, you may be feeling that writing functionality in simple objects is enough to build a complex application, where rest of the supporting services can be provided externally. Spring has be the front runner in building technology around POJOs. But Sun’s recent releases of SDK and JEE are focusing on the same principle. EJB is not left out from Sun’s this focus, …

This tutorial is to give you complete understanding of Spring MVC concepts along with important code examples.

Most of the presentation tier frameworks provide support to client side validations. Spring MVC is not different in this principle. Just that the way it is implemented is little different.
