System Requirements

You need to have Java 6 or Java 7 (also known as JDK6/JDK7) installed on your system. Get it here:

JDK download

Note that only the version labeled JDK will work. Not the one labeled JRE, nor the one that comes with NetBeans, nor the EE version.

Debian/Ubuntu users should install the JDK via the package management system rather than using the links above. See the installation instructions.

Details about system requirements are here.

On MacOS X 10.5+, a recent Java SDK version is installed by default. You do not normally need to install Java on this system. See here for more information.
