Spring configuration xmls are base of a Spring project. Hence it is important to manage these files from start. Here are the best practices that would help to manage these files effectively.

URI-template is a string containing one or more variables or place holders which can be replaced to generate URL out of this. Though this feature appears simple, but uses of this can be significant. 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.

Spring framework used dependency injection (DI) principle (also called as inversion of control) to provide a container that can offers many services to Java applications. Not only services but it also integrates AOP framework, Database access frameworks to ease a programmer’s life. The popularity of this framework made Sun to re-look at its Java technology stack to make coding easy. Impact of this framework can be easily seen on Java 5 release, where we can see drastic change in EJB framework. Annotations used to inject objects are also result of …

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, …
