我在eclipse7.0建了一个web project
然后建了一个a.jsp,代码如下：
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
System.out.println("456");
%>
<html>
<body>
123
</body>
</html>
又在scr包下建了一个类b.java的类
System.out.println("456");
运行这个类后 456 可以在控制台输出
但启动了tomcat6.0后 运行a.jap 结果是浏览器中显示了123
但控制台没有显示456
只显示一些看不懂的错误信息：
