If I'm not wrong, Windows 2K has the facility to set  Environtment
Variables. All U have to do are open your control panel window, click
System icon, go to Advanced tab. Then click Environments Variables button.
Here you can set your PATH variable to add  java binary path.
You don't have to restart your computer after doing this. Just open your
Command Prompt, type echo %PATH%. if java binary path appears then you've
done correctly.
