小弟刚学不久.到网上去下了tomcat和jdk安装以后,又随便找了个程序来实验一下。
<%@ page contenType="text/html; charset=gb2312"%>
<%@ page import="java.util.*"%>
<html>
<head>
<title>yanshi</title>
</head>
<body>
<h2 align="center">duixiangyanshi</h2>
<%
String appAttrib;
int count=0;
Enumeration attributes=pageContext.getAttributeNamesinScope(pageContext.APPLICATION_SCOPE);
while(attributes.hasMoreElement())
{
count +=1;
appAttrib=(String)attributes.nextElemnt();
out.print("Application属性" +count+ ":" +appAttrib+ "<br>");
}
%>
</body>
</html>
可是一用http://localhost:8080/s3.jsp打开就出现
