This error comes up when java can't find the class file that you're trying to run. Either you haven't compiled the program, or something else is wrong. If you're compiling & running through TextPad, then the .java file & the .class file should be in the same folder. If they are, then try putting .; at the start of your classpath environment variable. On 2000/XP, it's definitely found by right-clicking My Computer, Properties, Advanced, Environment Variables, and then it's under System Variables. If it's not already there, create a new one called CLASSPATH with the value .;

Try System (with uppercase S).
