In any case, you need to install the JDK first: Download.

You also should set the environment variable JAVA_HOME to the directory you installed the JDK into, e.g. C:/Programme/Java/jdk1.6.0_12. The variable PATH should contain the bin-Folder, e.g. %PATH%;%JAVA_HOME%\bin.

Hint: Under Windows, you can set environment variable by:

• Hitting Windows+Pause
• Tab “Advanced”
• Button “Environment Variables”
