过滤器和我配置到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>

Answer 1

web.xml中同时配置filter 和 Dwr应该不会出问题的 
你试试调整一下配置的顺序看看

Answer 2

你的ajax请求 被 filter给过滤掉了 

Answer 3

9494/* 过滤所有啊。<filter-mapping>
        <filter-name>loginfile</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

Answer 4

<servlet-mapping>
        <servlet-name>dwr</servlet-name>
        <url-pattern>/dwr/*</url-pattern>
    </servlet-mapping><filter-mapping>
        <filter-name>loginfile</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
你两个都做了过滤了dwr里面也有过滤器的，所以它们冲突了
<filter-mapping>
        <filter-name>loginfile</filter-name>
        <url-pattern>*.jsp</url-pattern>
    </filter-mapping>
只对jsp页面进行过滤，不要过滤全部的。
