Installation requirements for game developers

At the time of printing, the jMonkeyEngine SDK needs 40 MB of memory, plus enough memory to load the particular game's assets. Your computer should have a minimum of 1 GHz CPU, and your graphic card must support OpenGL 2.0, or better. Suitable graphic cards include ATI Radeon 9500, NVIDIA GeForce 5 FX, Intel GMA 4500, and all newer ones.

You can use the jMonkeyEngine SDK on all operating systems that support the Java Development Kit 6 (JDK 6) or better. Currently this includes Windows XP/Windows Vista/Windows 7 or better, Mac OS X 10.5 or better, and Linux kernel 2.6 or better.

Enter the following command in your terminal to check whether you have the required Java Development Kit (JDK) installed:

javac -version

If this command returns javac 1.6.x or better, then your Java installation is set to go. If you still need to install the JDK, click on the Download JDK button at http://www.oracle.com/technetwork/java/javase/downloads/index.html and follow the installation instructions there.
