There are plenty of servlets that don't start with /servlets.
I went to
java.net, clicked on a story and got https://www.dev.java.net/servlets/ProjectList?type=Projects&mode=TopLevel . How does that could in this story?
Plus this kind of stuff is pointless anyway as a) it misses probably 50% of the java / MS sites out there and b) it only reports on what's on the very first layer of a website. Maybe you have a .jsp page that talks to some SQL server.
Its like publishing a paper that Kohler's the most popular faucet as 80% of homes have Schlage key lock on the front door versus Medeco.
