There you are ready to go!

Answer 3

This error occurs when you haven't added the right directory to your PATH.

First find out which directory you've installed java in and try running it directly. Something like this in my case:

c:\> "c:\Program Files\java\jdk1.7.0_11\bin\java" -version

Once you've got the right version add the bin directory to the PATH environment.
