This is actually a following to another post of mine titled "How to make Tomcat serve/listen to one more port?"
When I implemented my method of adding a new <Service> element in server.xml in order to make Tomcat serve one more port, I seem to have user/authentication problem within VMWare Server 2. I thought the problem came from the fact that I duplicated an existent <Service> element, and in that element, there's this <Realm> element: <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/> But in Tomcat's official doc about "Realm" ( http://tomcat.apache.org/tomcat-6.0-doc/config/realm.html), I can't find anything about the "resourceName" attribute. So I suppose both websites are accessing the same "UserDatabase", right? So I remove the <Realm> element from the new <Service> element, and the problem seems to have gone. But I'm not sure what I've done is correct: so what happens if there's no <Realm> element within a <Service> element? Tomcat doc doesn't seem to have any mention of it....
