Where should JAVA_HOME be pointing to - JDK or JRE? I have seen that in few websites. It is set to JRE and in others it is to JDK. And is it dependant on Java version in any way?

JDK stands for Java Development Kit, while JRE stands for Java Runtime Environment. JAVA_HOME should point to a JDK not a JRE as the JDK is used for development purposes. JDK includes the compiler and other tools needed to develop Java applications while JRE does not.

See How to set java_home on Windows 7? on how to change your JAVA_HOME.

You should set JAVA_HOME to the JDK.

Relevant Documentation:

  1. Install the JDK software.

    a. Go to http://java.sun.com/javase/downloads/index.jsp.

    b. Select the appropriate JDK software and click Download.

    The JDK software is installed on your computer, for example, at C:\Program Files\Java\jdk1.6.0_02. You can move the JDK software to another location if desired.

  2. To set JAVA_HOME:

    a. Right click My Computer and select Properties.

    b. On the Advanced tab, select Environment Variables, and then edit JAVA_HOME to point to where the JDK software is located, for example, C:\Program Files\Java\jdk1.6.0_02.
