What's this scope?

Question

Hi,I've been troubled by this scope problem for a while.Here is the fragments of a jsp file:
//codes.
<%
String name="hello";                                                //(1)
//pageContext.setAttribute("name",name);          //(2)
%>
<c:out value="${name}"/>                                       //(1)
<!--
  <c:out value="${pageScope.name}"/>                                     //(2)
-->
//end.Here the codes work OK, but if mixed (part 1 and part 2), there's no output. So what are the scopes of the 'name' variable in both parts?
Any help is greatly appreciated.Thanks in advance.

Since you are already writing this with JSTL there's no need to use JSP Scriptlets anymore.
The above could be changed to much simpler code as follows:
<c:set name="hello" value="Micky"/>
${name}In the above code the default scope is "page".
A variable in a JSP can have page, request or session scope.
A variable in page scope only exists when the code in that page is executed, once the JSP page is closed or changed the page scope variable will no longer be available.
