Are you getting compile errors, file not found errors or something else? What platform are you on? If you're running on Windows and are getting: 'javac' is not recognized as an internal or external command, operable program or batch file.' Then it's most likely a path issue.

If you get a screen full of options then there's nothing wrong with the install. Also, try using the full path to the javac.exe in your compile command.

To do this you have to change the environment variable. Search on google for: environment variables java classpath On windows --> control panel --> system --> advanced tab --> environment variables button --> then you have to change both the "path" and "classpath" environment variables make sure to NOT delete the path environment variable or you are kinda screwed.
