Here's a snippet of my web.xml that shows the filter:
<servlet>
<servlet-name>ReqMgr</servlet-name>
<servlet-class>infoIsland.ReqMgr</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>ReqMgr</servlet-name>
<url-pattern>/members/servlet/ReqMgr</url-pattern>
</servlet-mapping>
<!-- Filters Here -->
<filter>
<filter-name>CheckUser</filter-name>
<filter-class>infoIsland.CheckUser</filter-class>
<init-param>
<param-name>loginPage</param-name>
<param-value>/login.jsp</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CheckUser</filter-name>
<url-pattern>/members/*</url-pattern>
</filter-mapping>
Interesting, though, the filter is AFTER the servlet. Does that mean tomcat
is finding them?
However, it all works when the classes are exploded, filters, servlets, & all.
I've tried the jar -tvf, and it works OK. In fact, I just jar 'em up right
from the WEB-INF/classes directory, move 'em over to lib, and delete the
directories underneath classes. That's the way I produce the jar. Is there
something supposed to be in it that I'm missing?
