what is the difference between page and request scope prasanna

page - You can use the Bean within the JSP page with the <jsp:useBean> element or any of the page's static include files, until the page sends a response back to the client or forwards a request to another file.
request - You can use the Bean from any JSP page processing the same request, until a JSP page sends a response to the client or forwards the request to another file. You can use the request object to access the Bean, for example, request.getAttribute(beanInstanceName).
Basically, page and request scope both end when your JSP page finished processing. So even if a FORM is sent to the client by JSP, when that FORM is submitted it will be a new Request. I think the only difference between page and request is if the bean persists between forward() calls.
hi, Page Scope is the smallest scope, and is a representation of the PageContext object for your JSP. Each JSP has it's own page scope, so objects in the page scope of one JSP are not accessible to other JSPs. This is sorta like making a private variable in Java.
