installing jigsaw

Hi

I have downloaded the jigsaw application and installed it on my a
standalone pc. I have set my classpath to include the jigsaw and jdk
classes. On launching the server I get an error message as indicated
below:

c:\>java w3c.jigsaw.Main -root c:\jigsaw\jigsaw
loading properties from c:\jigsaw\jigsaw\config\server.props
Unable to launch http-server:w3c.jigsaw.http.httpd
[initializeProperties]: [host] undefined
Unable to launch admin-server:w3c.jigsaw.admin.AdminServer
[initializeProperties]: [host] undefined.
***FATAL Error:
No servers launched!


what am I doing wrong?
