I’ve recently started using Git, which I’ve found I much prefer to Subversion for two reasons. The first is that it’s really fast since almost all commands are run locally. The second reason is that Subversion litters your source code with .svn directories and should you accidentally delete or move one then you’re in for Read More
In this tutorial, I use the H2 database, which you can utilize by downloading the jar or you can replace with your own DB.

At the end, I’ll show you how to add your brand spankin’ new interceptor to your Read More
One of the first things you’ll want to do after getting started with Struts 2 is create more complex user interfaces.

Struts 2 is an MVC web development framework. It is based off of Web Work and has far less configuration than the original Struts.
