Problem running hop.bat

Microsoft Windows 2000 [Version 5.00.2195] Copyright 1985-2000 Microsoft Corp. C:\click>hop Starting HTTP server on port 8080

java -jar "c:\click\launcher.jar" -w 8080 -h "

-jar: illegal argument Usage: java [-options] class

Yes, I already did my homework. I read help.antville.org

It is the wrong java version

Java -version Java -version "JDK1.1.8"

But, I already try to install an update (JDK 1.4.2) and it did not work. After that the instalation finishes successfully, I did restart the server and java -version remains "JDK1.1.8"

And also, I read help.antville.org

It is a web server based on windows 2000 server and I am trying to run antclick concurrently. I'm probably doing something really wrong.

Any ideas?

Thanks in advance, for any help!
