apache+tomcat配置虚拟主机的问题

我用apache+tomcat+jk2配置好了jsp环境
然后在设置
<VirtualHost *:80>
    ServerAdmin admim@test.cn
    DocumentRoot "/home/test/www"
    ServerName www.test.cn
    DirectoryIndex index.htm
    ErrorLog logs/test.cn-error_log
    CustomLog logs/test.cn-access_log common
    <Location "/*.jsp">
         JkUriSet worker ajp13:localhost:8009
    </Location>
    UserDir public_html
</VirtualHost>
现在问题是,当我把jsp文件放在/home/test/www目录下可以执行.
但是只要import 一些类的jsp文件,全部告诉找不到类
报错
org.apache.jasper.JasperException: Unable to compile class for JSP

Generated servlet error:
/usr/local/tomcat/work/Catalina/ict.computercol.net/_/org/apache/jsp/ict/index_jsp.java:6: package cn.edu.bitc.ict.news does not exist
import cn.edu.bitc.ict.news.*;
^


Generated servlet error:
/usr/local/tomcat/work/Catalina/ict.computercol.net/_/org/apache/jsp/ict/index_jsp.java:8: package com does not exist
import com.GetDateTime;

是不是还有什么地方需要在/etc/httpd/conf/workers2.properties或者web.xml或者server.xml里面配置呢?
