Question

在我的jsp页面中我导入了类，它在我的电脑上运行文件在tomcat 7上，但是当我将它上传到我的服务器时，它给jsp文件编译错误我的代码

!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<%@ page import="com.*" %>
<%@ page import="DIO.*" %>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>

和我收到错误的地方是

<td class="value"><%= com.PageCounter.getIntTodaysCount() %></td>

我的类PageCounter在com包内，它在我的本地主机pc上运行文件上传到服务器时错误

，错误是

An error occurred at line: 32 in the jsp file: /index.jsp
PageCounter cannot be resolved
29: <table cellspacing="0" class="info_table"   style="height: 175px" >
30: <tbody>
31:   <tr>
32:     <td class="value"><%= PageCounter.getIntTodaysCount() %></td>
33:     <td class="full">Visits Today</td>
34:   </tr>

由于tomcat版本的改变

，它将会发生

任何建议都会有很大的帮助

错误是

An error occurred at line: 51 in the jsp file: /index.jsp
DIO cannot be resolved to a type

48: <div class="portlet-header">
49: <h4>Upcoming Events</h4>
50: </div> <!-- .portlet-header -->
51: <% DIO sharedDataBase = (DIO)application.getAttribute("sharedDataBase");
52: String[][] eventData=sharedDataBase.getData("select eventName,eventDescription,eventDate from listOfEvents order by eventDate desc", 10);%>
53: <div class="portlet-content">
54: <marquee direction="up" onmouseover="stop()" style="height: 200px" onmouseout="start()" scrollamount="2"

页面计数器类

package com;

import java.util.Date;
import java.sql.SQLException;

import DIO.DIO;

public class PageCounter {
    private static int count;
    private static int todaysCount;
    private static Date previousDate=new Date();

    public static int getIntTodaysCount(){
        Date date = new Date();
        if (previousDate.before(date)) {
            ++todaysCount;
        }else{
            previousDate=date;
            todaysCount=1;
        }
        return todaysCount;
    }

    public static int getIntCount(DIO sharedDataBase){
        count++;
        try {
            sharedDataBase.updateData("update pageCount set pageCount="+count+" where pageCountId=1");
        } catch (SQLException e) {
            e.printStackTrace();
        }
        return count;

    }

}

导入类成功，但尝试使用它时会出错
