cannot get Filters to work with Tomcat 5.0.16

[Patrick Scheuerer]

Hi,

I cannot get Filters to work with Tomcat 5.0.16.

Here are my filter definitions in web.xml:
<filter>
    <filter-name>UserFilter</filter-name>
    <filter-class>ch.ctc.support.common.UserFilter</filter-class>
</filter>
<filter>
    <filter-name>AdminFilter</filter-name>
    <filter-class>ch.ctc.support.common.AdminFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>UserFilter</filter-name>
    <servlet-name>/*</servlet-name>
</filter-mapping>
<filter-mapping>
    <filter-name>AdminFilter</filter-name>
    <url-pattern>/admin/*</url-pattern>
</filter-mapping>
Every time Tomcat tries to start the context I get the following exception:

java.lang.IllegalArgumentException: Filter mapping must specify either a 
<url-pattern> or a <servlet-name>

What the hell is going on here? I DID specify a <url-pattern>!  What am I doing 
wrong? Any help would be highly appreciated!

Thanks,
Patrick
