web.xml: url-pattern in filter-mapping

[Ron Newman]

In Tomcat 4.1.24, if I have this in my application's web.xml file:

    <filter-mapping>
      <filter-name>Budget Filter</filter-name>
      <url-pattern>/*.jsp</url-pattern>
    </filter-mapping>

the filter never gets called for any of my JSPs. But if I change the url-pattern line to this:

      <url-pattern>*.jsp</url-pattern>

the filter does get properly invoked.
Can someone explain why? All of my JSPs are at the top level of my web application's directory, so they all should match the pattern /*.jsp .
