Java is not recognized as an internal or external command, operable program or batch file

This basically means that Java is not installed or it is not in the path.

Remember that that the Path is in Start>Control Panel>System>Advanced System Settings>Environmental Variables

Scroll down in the bottom box and look for the line that says 'path' click edit.

At the end add the path to java which is typically something like: C:\Program Files (x86)\Java\jre6\bin
