WicketFilter cannot resolve filterPath if filterMappingUrlPattern is not configured

[Mikko Pukki]

Hi,

We noticed this while running our application in an environment where firewall 
blocks all connections to outside addresses.
Adding filterMappingUrlPattern parameter helped.

so for instance helloworld's web.xml 
(http://wicket.apache.org/learn/examples/helloworld.html) would be something 
like:

<web-app>
    <display-name>Wicket Examples</display-name>
    <filter>
        <filter-name>HelloWorldApplication</filter-name>
        
<filter-class>org.apache.wicket.protocol.http.WicketFilter</filter-class>
        <init-param>
          <param-name>applicationClassName</param-name>
          
<param-value>org.apache.wicket.examples.helloworld.HelloWorldApplication</param-value>
        </init-param>
        <init-param>
          <param-name>filterMappingUrlPattern</param-name>
          <param-value>/*</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>HelloWorldApplication</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
</web-app>
