我受不了了！菜鸟搞了3天了，还是不正确！！！
我用myEclipse开发javaBean
在src上建了一个包com，com下建了bean类如下：
package com;
public class Counter {
public Counter(){
}
private int count=0;
public int getCount(){
count++;
return count;
}
public void setCount(int newCount){
count=newCount;
}
}
jsp代码如下：
<%@ page language= "java " import= "java.util.* " pageEncoding= "ISO-8859-1 "%>
<html>
<head>
<title> My JSP 'Count.jsp ' starting page </title>
</head>
<body>
<jsp:useBean id= "myBean " scope= "page " class= "com.Counter " />
<%= myBean.getCount() %>
</body>
</html>
但是死活就是不正确！！

3 错误
没有道理啊！我实在不知道什么原因了~请各位高手解释下！！！
------解决方案--------------------
在webapps目录下新建立一个目录Test,具体目录如下：
Test
-index.jsp
-WEB-INF
--web.xml
--classes
---Counter.class
然后
