VRaptor3 is a fully-fledged Java Web framework focused on fast development and maintainable code. It intends to make RESTful application development easy. A resource corresponds to a business logic annotated with its path and HTTP method. It runs inside DI Containers (Spring or Pico out of the box) and, therefore, enables full integration with them. Also, using Hibernate is easier: its session is automatically injected by VRaptor, so you just have to use it. VRaptor3 is refactor-friendly, especially in its redirecting configuration. It is also nicely extensible.
BitNami Jenkins Stack is an easy-to-install distribution of the Jenkins application. It includes pre-configured, ready-to-run versions of Tomcat and Java, so users can get a Jenkins installation up and running in minutes after answering a few questions. Jenkins, previously known as Hudson, is a continuous integration server. Built with Java, it provides over 400 plugins to support building and testing virtually any project. It supports SCM tools including CVS, Subversion, Git, Mercurial, Perforce, and Clearcase, and can execute Apache Ant and Apache Maven-based projects, as well as arbitrary shell scripts and Windows batch commands. It can also monitor executions of remote tasks.
Mr.Java is a Java IDE that is one step above a command line interface, but not quite as confusing as an IDE. It will compile for you, add libraries to your class path, and run the whole thing, with three simple buttons. Drag a library or Java source file over the window, and it will be put in the right folder. When running programs, the stout is written to a file cleverly named “stdout”, and the std err is cleverly written to file named - you guessed - stderr.
