What OS are you using? Have you made any changes to server.xml in $CATALINA_HOME/conf?
Try accessing it locally first, then try it from one of your friends computers.
If it then fails, try and shutdown the firewall on the same machine as is running the tomcat instance. Depending on its configuration it may prevent incoming connections on the default port 8080. If that was the issue, reactivate the firewall and open the desired port 8080 for http traffic.
Get to know the logs, they are usually located in $CATALINA_HOME/logs/, have a look in catalina.out for example. If you´re unsure weather the server is up and running or not and whatever issues may´ve arisen, thats the best place to check. There it will state which webapps it finds and if it was successfull in deploying them. You can also go to the server root with your browser at localhost:8080 and check if you get the welcome screen.
Good luck!
