I have created .war file from netbeans.
can i run this file?
You don't actually "run" it. You install it (deploy) into a J2EE server and run the server. When your web browser submits a URL that matches the application context that you deployed, it routes the URL to your application code.
For basic servelt/JSP WARs, you can use Tomcat as your webapp server. If you're using more advanced J2EE features such as EJBs, you need a full-function J2EE/JEE server such as JBoss, WebSphere, WebLogic or something similar.
