J2EE world has a lot of tools which make our development time easier and shorter, sometimes people are asking about web application listener and when to use them. I will try to write how to add a web application listener with Netbeans 7.0, if you dont have any idea about web application listeners, try to understand what are web applicaiton listeners.

1. Web application listeners are added by left clicking on the project, then click New > Other
