I created one web application so i want to store my past logged user name list for comparing new users which are going to login. so how i do that by using ServletContext ? or is there any other way?
A:
In JSF, application scoped managed beans are stored in the servletcontext. So, you could basically just create and declare an application scoped managed bean and put the list in there.
However, there are probably better ways for the particular functional requirement which is yet unclear in the question. At least, implementing a HttpSessionListener or HttpSessionBindingListener is probably a better idea since logins are usually coupled to the HttpSession.
Here are several examples:

The examples are available in the links in the answer. In the future, you need to elaborate the "i am not able to do" in more detail. What are the functional requirements? What code do you have as far? What exactly happens? What exactly happens not? As far now it much sounds like that you couldn't even write a single line of code or couldn't get it to compile. My direct answer would then be: learn Java first.
