Page Scope VS request Scope VS session Scope Vs application scope

[sree visu]

I am not very clear regarding the four scopes.Could anyone please explain me the exact differences between all four of them please.

Thanks for your help in advance

Hi,

Scope is nothing but lifetime object

1.page - only in the particular jsp

2.request- only in the jsp to which you forward your request object

3.session- it is available until the session is invalidate(you can access it from any jsp)

4.application-it is available until the web application or server shutdown(you can access it from any jsp).available through whole application


Hope This Helps
