Where Can get Domino Server's name for Servlet Deployment

I copied my servlet class to data/domino/servlet directory, and tried to run from the browser for the servlet, but I got http 404 not found error.

From the designer help document, it ask to replace the following “yourserver” with my own server’s name.

yourserver.com

But I found from server document, my server have several name:

Server name:TOR6FLOBS70/XXX

Server title:   XXX Domino

Fully qualified Internet host name:	TOR6FLOBS70.Canada.XXX.lan

which one is my server’s name?

I can open from the browser http://127.0.0.1/, which will show the domino help link.
