内容：
 两种方式
 
<c:set var="s1" value="This is One" scope="request" />
out.print(request.getAttribute("s1") ;
 
<c:set var="s2" value="This is Two"/>
out.print(pageContext.getAttribute("s2"));
 
----------------------------------------------------
JSTL 变量由 JSP 读取
 
<c:set var="JspValue1" value="Java Language One" scope="request" /> 
<c:set var="JspValue2" value="Java Language Two"/>
<%
String JspValue3 = request.getAttribute("JspValue1").toString();
String JspValue4 = pageContext.getAttribute("JspValue2").toString();
          
out.print(JspValue3);
out.print(JspValue4);
%>
 
----------------------------------------------------
 
JSP 变量由 JSTL 读取
String strContextPath = request.getContextPath();
 pageContext.setAttribute("ContextPath", strContextPath);
..
<c:out value="${ContextPath}"></out>
