刚开始学javabean...请教各位前辈我的程序哪里有问题....

我把类文件放在默认包下没有建立新包...类文件Compare.java如下

import java.util.Date;



public class Compare{

	//设置两个日期

	private Date firstDate;

	private Date secondDate;

	/*判断*/

	public String compare()

	{

		if(firstDate.before(secondDate))

			return "第一个时间早";

		else if(secondDate.before(firstDate))

			return "第二个时间早";

		else return "两个时间相同";

	}

	//取得第一个时间

	public Date getFirstDate()

	{

		return firstDate;

	}

	//设置第一个时间

	public void setFirstDate(Date firstDate)

	{

		this.firstDate=firstDate;

	}

	//取得第二个时间

	public Date getSecondDate()

	{

		return secondDate;

	}

	//设置第二个时间

	public void setSecondDate(Date secondDate)

	{

		this.secondDate=secondDate;

	}

}

在newCompare.jsp文件如下

<%@ page language="java" import="java.util.*" import="java.util.Date" pageEncoding="gb2312"%>



<%

String path = request.getContextPath();

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

%>



<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

  <head>

    <base href="<%=basePath%>">

    

    <title>JSP示例程序2</title>

    

	<meta http-equiv="pragma" content="no-cache">

	<meta http-equiv="cache-control" content="no-cache">

	<meta http-equiv="description" content="This is my page">

	<!--

	<link rel="stylesheet" type="text/css" href="styles.css">

	-->



  </head>

  

  <body>

    <jsp:useBean id="date" class="Compare" scope="page"></jsp:useBean>

    <%

    	date.setFirstDate(new Date());

    	date.setSecondDate(new Date(107,6,23));

    	

     %>

     <font size="4"><strong>本页面展示比较两个日期时间的前后:</strong><br>

    	第一个时间:<jsp:getProperty property="firstDate" name="date"/><br>

    	第二个时间:<jsp:getProperty property="secondDate" name="date"/><br>

    	<%out.println(date.compare()); %>

    </font>

  </body>

</html>

在myeclips中没有错误
在浏览器中报错:
org.apache.jasper.JasperException: Unable to compile class for JSP:

An error occurred at line: 27 in the jsp file: /newCompare.jsp
Compare cannot be resolved to a type

An error occurred at line: 34 in the jsp file: /newCompare.jsp
Compare cannot be resolved to a type

我用的tomcat...
应该不是tomcat的问题,能运行其他jsp网页
应该是类文件的问题...如果要是路径有问题myeclipse应该报错,现在已经能通过,就不该是路径问题...
我的class文件在"myeclipse\工程名\WebRoot\WEB-INF\classes"中

请各位前辈帮忙分析分析~~~~先谢过!
