Event Hook

 Event Hook

We know about the Event in Servlet. Event is nothing but whenever we want we can deploy the application and whenever we don’t want we can undeploy, likewise user log-In, user-Logout . These are the some of the events in web application. In this way  we are having  preprocess and postprocess.

In Event hook we can customize the community. We can implement user-defined community  by Overriding run().

Here 1^st  we need to create User and Community. After creating  them add User to Community.

Note: It is used to change the URL (web/guest/home to web/suresh)
