How to access my webapp using public IP address instead of localhost?

Is it possible to access my web application using public IP address like,

http:/AppServerIP:8180/myWar/myServlet

If I hit through Web Server like below it works fine (Servlet gets invoked)

http:/WebServerIP(public)/myWar/myServlet

When am trying to invoke the Servlet from my Application Server, am getting the below exception.

java.net.ConnectException: Connection timed out
        at java.net.PlainSocketImpl.socketConnect(Native Method)
        at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:333)
        at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:195)
        at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:182)
        at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:366)
        at java.net.Socket.connect(Socket.java:529)
        at java.net.Socket.connect(Socket.java:478)

Servlet gets invoked internally through code when another end User concurrently logs into same port. So, I want to call that Servlet and invalidate the current session. I don't want to go through Web server as it might send the request to other ports as well.

My project Stack : Jboss AS 5.1.0 GA, Apache web server 2.2.5 and Port Number is 8180

Solution

First of all, you need to get your public IP address, which you can find using ipconfig command on Windows machine.

Then, you can try like this

http://<your_public_ip_address>:<your_webserver_port>/

It will show you server welcome page. And you need to open your specific project. Then, try this

 http://<your_public_ip_address>:<your_webserver_port>/myproject/

It will show, your index or home page of your project.

Note : You need to be sure for your IP Address and Port Number
