How to Set Java_Home on Windows 7

Setting JAVA_HOME in Windows?

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.

Setting JAVA_HOME

As many have mentioned I had to add...

C:\Program Files\Java\jdk_version\bin

However what was not mentioned and was stopping this from working was that I had to make sure
java\bin directory is in the path statement before the windows\system32 directory, otherwise this will not work.

I was able to find the information here.
