Scope variables are basically used for sharing the data.
If you use page scope,the JSP object can be accessed only from within the same page where it was created.
If you use request scope, the jsp object can be accessed from any page that serves the request.
If you session scope, the jsp object is accessible from pages that belong to the same session from where it was created.
If you use application scope,the jsp object can be accessed from any page across the application.
