[jcifs] Blank Page

[Gana]

Hi, I have a problem with JCIFS and TOMCAT. I have the latest (or close to ) of 
both of these. i added the filter tags to the web.xml file and run the 
application. However the entire web application is presented as blank pages. 
there are no error messages. even if i put garbage for the domain controller 
attribute it still displays a blank page. 

is this a problem with my web.xml or with JCIFS or with tomcat. The web.xml 
file looks like the one below


<web-app>
 <description>Timetables</description> 
  <display-name>Timetables</display-name> 
<filter>
    <filter-name>NtlmHttpFilter</filter-name>
    <filter-class>jcifs.http.NtlmHttpFilter</filter-class>

    <init-param>
        <param-name>jcifs.http.domainController</param-name>
        <param-value>hello</param-value>
    </init-param>
</filter>

<filter-mapping>
    <filter-name>NtlmHttpFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>

thanks in advance
