how to access webpage hosted on tomcat server from the android mobile

Question

I have designed a webpage and run that on my browser using tomcat server http://localhost:8084/neclogin/main.jsp

I also accessed it from my android emulator it works well. http://10.0.2.2:8084/neclogin/main.jsp it works well.

But when I tried on my real device (connected to PC via hotspot) http://192.xxx.xxx.xxx:8084/neclogin/web/main.jsp

It shows on browser that HTTTP 404 ERROR - DESCRIPTION :requested resource is unavailable

I am confused whether my android mobile is unable to connect to localhost or can't trace the path of my main.jsp

FOR MORE DETAIL

1)windows 7
2)NETBEANS IDE WITH APACHE TOMCAT SERVER 8.03
3)**Both connected via wifi hotspot on my mobile**
4)path to my main.jsp is `C:\Users\dell\Documents\NetBeansProjects\neclogin\web\main.jsp`
5)path to my tomcat server installed is `C:\Program Files\Apache Software Foundation\Apache Tomcat 8.0.3`

i have disabled my windows and antivirus firewall

First try to access http://192.xxx.xxx.xxx:8084/neclogin/web/main.jsp from your PC to see if the IP is correct.

a) If that works and you can access it, then indeed there is a problem with the external access and the problem is somewhere in your firewall settings or alike. Potentially it doesn't let traffic through 'non-standard' ports (80,433 etc)

b) If you can't access it on your PC either using then you got the IP wrong. Try running ipconfig from the command line and see if with the IP listed there it works. ipconfig will return a bunch of different IPs you need to look for the one that starts with 192 most likely labeled as IPv4 or something like that.

It's also worth checking what the 404 message looks like. If it's tomcat's 404 page then you're almost there as you can access tomcat but not using the correct path.
