好像是过滤器类出错不知如何配置？？

#2

你把过滤器的配置和调用的部分代码发给我看看！

#3

上面的兄弟有没有qq 或者什么通讯类的

#4

我也不知道什么是过滤器类这是我在网上下的hfscm源码想把它配置到我的项目中运行看看就是运行不起来帮忙看看

兄弟从你的错误提示中已经可以看出来啦，java.lang.NoClassDefFoundError: org/apache/log4j/Logger，这是找不到你的类呀，你把log4j.jar文件添加到你的工程里不就可以了吗？

#7

哈哈是啊我已经添加啦
但是启动tomcat的时候还是出现一系列的错误信息

在WebRoot文件夹中有大量的红叉！！！

import org.apache.log4j.Logger;
找不到这个类
你把那个jar包扔到那里去了？什么目录下？

#9

我看了一下好象 WEB-INF下面的lib 文件夹没掉啦下面的jar都找不到

#10

你的环境肯定有问题，还有你将web.xml的相关配置发给我看看。。。
