I have done a small web development project using eclipse. It runs well when I try running it on browser with url localhost:8080/myproject/home.html. But if I want to access it on another machine (laptop, mobile, etc. using the same wifi) it is not possible; it is not able to connect.

After Googling for a while found out that I have to use the IP address instead of 'localhost'. So I tried 10.0.0.4:8080/myproject/home.html, but still does not work. In fact i am unable to open that url on the same machine (where localhost:8080/myproject/home.html works fine). I also added a new Inbound rule in control panel firewall settings, allowing access to all ports for protocol TCP. Still have problem in running application with the url 10.0.0.4:8080/myproject/home.html (both on same machine as well as laptop and mobile).

FYI i am using Eclipse Indigo, Apache tomcat 6.0 and server.xml file contents is as below:

Maybe you should bind your server to 0.0.0.0 not 127.0.0.1

hi @aisensiy thanks for quick reply,... can u plz guide how do i bind it to 0.0.0.0... –  Robert Dec 9 '12 at 9:18

The local tomcat server running from eclipse binds to localhost (127.0.0.1) by default, which means it will only accept requests at that address.

When you try accessing it from the machine's IP address, it is rejected because the request is for 10.0.0.4, which the server is not bound to. This explains why you cannot access it at that IP on the same machine.

This should explain how to bind to another IP address.

i tried adding the value for 'address', but still same problem. i tried values 10.0.0.4(ip of the dev machine) and 0.0.0.0 but still cannot open on browser with url 10.0.0.4:8080/myproject/home.html. can you plz check the contents of server.xml and let me if there are any errors in it. (i have edited the question and added it there..) –  Robert Dec 10 '12 at 3:25
    
First try address=0.0.0.0. Make sure port 8080 is unblocked in your machine's firewall, or perhaps temporarily disable it. Also read this: stackoverflow.com/questions/6246127/… –  computmaxer Dec 10 '12 at 5:14
    
i tried with address=0.0.0.0 and my windows firewall is off for domain, home/work, public.. 10.0.0.4:8080/myproject/home.html still not working.. as i said earlier it is not opening in the same dev machine as well.. –  Robert Dec 10 '12 at 5:42
