In a previous post, I talked about new features and performance of java 1.7. Java 7 has now been released a while ago and Java 8 is coming.

regexp or in other words regular expression is something you have to regularly use in your applications. I've decided to write this post as a placeholder for regexp I believe are common and useful such as regexp for email validation or some you might use to replace characters in a string. I might write some piece of java code but you can use these regular expression in many other languages.

You will discover it and see how to use it. I will talk about the Garbage Collector as well, only basic things to be able to understand Visual GC.

I have been reading quite a lot about Java 1.7. There are articles about what's new, some code examples, some benchmark to compare performance with previous version of Java and discussion on when it will be released. I have decided to regroup all I have discovered in this article so that I and maybe you, won't have to spend hours surfing the web to find all this information.

In my previous post we have seen how to create a webapp. Today we will see how to use spring-jdbc which is the Spring Framework's JDBC abstraction framework. Thanks to this you will be able to connect your webapp to a database. In my example I will use mysql but it is really easy to use any other database.

This post is a short introduction on how to create a web application in java from scratch. We will use the springframework, a really popular java framework. The current stable version of this framework is 2.5.6 but we will see the features of the next major version: 3.0. At the time I write these lines it is in RC3 so it should be released pretty soon. I will do a short introduction about maven as we will use it. The IDE I am using is eclipse so if you don't already know about it, you can learn few things there.
