the first question should be: do you have an application server (
servlet container) installed - like tomcat?
How do you run this server? is it installed as "service" - that is does it get inited whenever you start your machine - or do you have to run the start.sh manually?
Just cause there's a "link" mentioned doesnt mean you can access it right away. The link for localhost means that there should be some webserver listening on that machine - so you first have to make sure it runs.
So what next if the tomcat is running? Deploy the file within the webapps directory, e.g. unzip it there... so that there's something like jforum-2.1.8/<actual files and folders> as subfolder of webapps...
Just to be sure you then could restart the application server (tomcat) so that the app gets properly loaded. Then you can finally click the link (easy huh? :-)) ... and if there's error messages displaying instead of a page you'd expect - check out the log files ...
Logs are the tomcat admin's best friend ;)
