搜索引擎无法在tomcat中运行。。。毕设急。。

我的毕设做的是搜索引擎。。现在前期工作都差不多了，就是最后将应用部署到tomcat中的时候出现了问题。。本人对JAVA,JSP等不怎么了解，懂得很少，遇到错误也不怎么会解决，忘高手指点，不胜感激。。错误如下：HTTP Status 500 -type Exception reportmessagedescription The server encountered an internal error () that prevented it from fulfilling this request.exceptionorg.apache.jasper.JasperException: Unable to compile class for JSP: An error occurred at line: 59 in the jsp file: /s.jsp

CharacterHandle类在jsp中import了吗？<%@ page import="com.xxx.CharacterHandle" %>
如上所述，或者"CharacterHandle"拼写错误，是不是结尾少个"r"（CharacterHandle+"r")？
我把jsp中的内容粘贴过来帮忙看看啊，你说的那个characterHandle已经包含在红色部分的那个包中了。。具体代码如下：%@ page language="java" pageEncoding="GB2312"%>
<jsp:directive.page import="java.lang.Integer"/>
<jsp:directive.page import="cn.edu.njut.search.util.*"/>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

就是这么拼写的。。你也帮忙看看这个jsp程序吧，我实在是看不懂啊。。万分感谢。。
看看你WEB-INF/lib目录下有没有cn.edu.njut.search.util这个包……
不好意思，好像我还没法上传图片。。在我的工程目录下，这个包是放在了JAVA RESOURCES/src下的。。当然我这个工程类型为Dynamic Web Project 然后其他的文件比如.html , .jsp等文件都是在WEB-INF下的，我是照书上来的。。整个工程都没报错。。
我是说你的web server下这个工程的WEB-INF/lib目录下有没有这个包。比如你用的是tomcat，则看看tomcat_home/webapps/your_project_name/WEB-INF/lib下
