myeclipse 控制台输出
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：

这种情况下 怎么样才能在控制台输出456啊？？？？？？？？？？？？？？？
不然很多其它jsp项目都没办法调试，错了都不知道死在哪
[解决办法]
Address already in use: JVM_Bind <null>:8080
错误信息是说8080端口已经被占用了！
[解决办法]
对，可能是8080端口被占用，也可能是你的welcome-file没设置成a.jsp
[解决办法]
端口占用，重启你的计算机
[解决办法]
端口被占用
楼主是在eclipse里面启动的tomcat吧？
把tomcat进行杀掉后再试试
[解决办法]
