In JSP , we can store an object in 4 scores : page, session, servlet, application. But how can they know each other? for example, how session could get the data stored in servlet/application/page?

actually, the key point is, how session/servlet/application can get pageContext ?

Thanks

Hello,
pageContext is one of nine implcit variables right? So it willnot be a problem on accessing ir-respective of scope right.
