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.

Till date we all know that Java compilation is not a runtime business. Write code, compile and generate byte code, deploy and run it on any jvm. But this restriction is removed from java 6. Now compilation is no more a pre-runtime business. Using APIs provided by java 6, we can generate classes runtime and compile to generate class files, which can be used further.Let us see the important classes we need in writing a programmatic compiler.

OK! Not sure how much you are concern about it, and how much data you have uploaded there. I am talking about your data on facebook.

It provides ready container to create and manage objects and also provides enterprise services to those objects. It provides ready components for different tiers of application e.g. web, middle/business and data access.
