You need to adjust your PATH variable. If you are using Windows XP, it's in the Control Panel:

Control Panel -> System -> Advanced -> Environment Variables -> System Variables

You'll need to add the directory where javac.exe is located to the PATH, which will vary according to where you installed JAVA. On my computer, it's:

C:\Program Files\Java\jdk1.6.0_02\bin

Add that directory to your PATH in the System Variables, then restart a new command window and try the javac command in the new command window.

Don't forget to separate it from the other ones with a semi-colon. So adding it to Vernon's

;C:\Program Files\Java\jdk1.6.0_02\bin
