过滤器和小弟我配置到Dwr有冲突，把过滤器去掉后可以运行了，大家帮看看

<welcome-file-list>        <welcome-file>index.jsp</welcome-file>    </welcome-file-list>    <servlet>        <servlet-name>dwr</servlet-name>        <servlet-class>            org.directwebremoting.servlet.DwrServlet        </servlet-class>    </servlet>    <servlet-mapping>        <servlet-name>dwr</servlet-name>        <url-pattern>/dwr/*</url-pattern>    </servlet-mapping>     <filter>        <filter-name>loginfile</filter-name>        <filter-class>huawei.FileLogins</filter-class>    </filter>    <filter-mapping>        <filter-name>loginfile</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>
