Question: How we can check in particular page the session will be alive or not?


U can use request.getSession(false); method in HttpServletRequest interface.It returns the HttpSession associated with this request or null if the request has no valid session. Source:

isAlive() method is used to check whether the session is alive or not.
If the method returns true,then sesion already exists and returns false when no session is found. Source:

there is no method isAlive() in HttpSession interface.
You just get session object by calling session=request.getSession().
if session is not null, means there is one active session. Source:

request.getSession() will always return a session object( if no valid session object then it creates new Session object )

We need to call request. getSession(false) and check it is not null - to know active session is present. Source:
