问题 I am trying to understand how exactly scope attribute in jsp:useBean JSP action tag works. In my understanding scope is used to indicate where the bean is located (request,session,application etc.), but after some testing I came across an interesting situation where it's not the case, please consider the following JSP code (I am using scriplets here just for the sake of simplicity): <%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1" import=
