Hi,
If you want to start tomcat automatically at startup of windows 2000, you can either register it as a service, or run regedit and add an item to the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run which contains the startup command.
Regards,
Kurt.
Here's a utility which you might find useful:
Invoker is a free administrative and development command line utility for Microsoft Windows NT 3.51/4.0 (Intel) that creates a registered service out of (most) applications that can be launched by the command line.
