filter mapping

["Lin, Zhongwu" <Zh...@AFCC.com>]

In tomcat 4.0,  how do I map filter ( "my filter" ) to servlet
"my simple servlet" ?

 
<filter-mapping>
  <filter-name>my filter</filter-name>
<!--  this does not work                   -->
   <servlet-name>my simple servlet</servlet-name>

<!--  this does not work neither                   -->
   <servlet-name>myservlet</servlet-name>

</filter-mapping>

<servlet>
  <servlet-name>my simple servlet</servlet-name>
  <servlet-class>com.controller.myservlet</servlet-class>
</servlet>

You can map a filter either by <servlet-name> or by <url-pattern>.  Given
the <servlet> definition you have below, your first option should be
correct.

So what request URI are you actually trying?  What happens?  What did you
expect to happen?  What does the rest of your web.xml look like?

One possible way this would not work is if you try a URL like:

  http://localhost:8080/myapp/servlet/com.controller.myservlet

or

  http://localhost:8080/myapp/servlet/my+simple+servlet

In either of these cases, you are using the "invoker" servlet that is
mapped to "/servlet/*", which creates its own servlet definition instead
of using existing ones.  For a filter mapping to work, the underlying
servlet *must* be mapped with a <servlet-mapping>.
