If you set the port for Tomcat to 8081,and using the url
http://myipadd/apps, nothing is going to happen because your colleague's web-browsers do not know to look on that port, they will be looking on port 80 of your machine. Have them try to connect to
http://myipadd:8081/apps (this works on my server as long as I open that port on the firewall). If there is a firewall or some other form of protection on the network you won't be able to do this either because all uneeded connections will hopefully be blocked. I hate to be too much more detailed because I don't know if this is on a workstation at work or at home. If it is at work, I would hate to have you open up your system to outside intrusion and have you end up losing your job or something.
