急急急 初学者遇到表单提交乱码问题?

[db_30]

我是一个初学者，对如何新建过滤器，在web.xml如何链接不知道？请高手指教！
具体问题：
遇到表单提交乱码问题，在tomcat的目录中复制SetCharacterEncodingFilter.class文件到D:\jakarta-tomcat-5.0.28\webapps\box\WEB-INF\classes\ch2\util\filter目录下
可是myeclipse无法编译通过以下是web.xml中的内容，请指教问题出在哪里？

在Console里显示：

严重: Error filterStart
2008-3-27 16:12:05 org.apache.catalina.core.StandardContext start
严重: Context startup failed due to previous errors
2008-3-27 16:12:05 org.apache.coyote.http11.Http11Protocol start

重新调整web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<filter-mapping>
