It (container) stores the scope attributes in the corresponding objects. Request scope in ServletRequest, Session scope in HttpSession, page scope in JspContext and application scope in ServletContext.

When you try to get the attributes, you call getAttribute() method on the corresponding object and it returns the attribute in that scope.

You can access all the scope attributes in Jsp page, using the implicit variable pageContext of type javax.servlet.jsp.PageContext methods: getAttribute(String name, int scope) and setAttribute(String name, Object value, int scope) to access those attribute directly.
