I installed Apache Tomcat on my Window XP Prefessional computer. My computer is connected to a on-campus Windows LAN (ADS domain) through a switch at my place. Apache Tomcat is the only web server, running at port 80.
The server runs normal locally. The IP address of the computer is obtained through DHCP. I used "http://149.*.*.*/FolderName/filename.html" to access pages. The problem is that my files, both *.html and *.jsp can't access from browsers from other computers, except my another computer connected to the same switch and my friend's MAC located on campus.
At first, I thought it was the problem with Firewall. But I set up port 80 for incoming traffic. I don't understand why some computers can access it but most can't.
Lin, not sure if you got this fixed. If the lan admin setup a firewall to block incoming traffic, there will be no use even if you open up the port 80 on your xp. Check with them and ask what can be used to get into your lan from outside. I used vpn to access apache/tomcat on my desktop.
