tomcat4.1 apache2 jk2 problem

<!-- Server Configuration File for Tomcat 4.0 on Debian
  You can find more complete examples in /usr/share/doc/tomcat4/examples/.

<!-- A "Server" is a singleton element that represents the entire JVM,
  which may contain one or more "Service" instances. The Server
  listens for a shutdown command on the indicated port.

  Note: A "Server" is not itself a "Container", so you may not
  define subcomponents such as "Valves" or "Loggers" at this level.
-->

<Server port="8005" shutdown="SHUTDOWN" debug="0">


<!-- A "Service" is a collection of one or more "Connectors" that share
    a single "Container" (and therefore the web applications visible
    within that Container). Normally, that Container is an "Engine",
    but this is not required.

    Note: A "Service" is not itself a "Container", so you may not
    define subcomponents such as "Valves" or "Loggers" at this level.
 -->

<!-- Define the Tomcat Stand-Alone Service -->
<Service name="Tomcat-Standalone">

  <!-- A "Connector" represents an endpoint by which requests are received
     and responses are returned. Each Connector passes requests on to the
     associated "Container" (normally an Engine) for processing.

     By default, a non-SSL HTTP/1.1 Connector is established on port 8180.
     You can also enable an SSL HTTP/1.1 Connector on port 8443 by
     following the instructions below and uncommenting the second Connector
     entry. SSL support requires the following steps (see the SSL Config
     HOWTO in the Tomcat 4.0 documentation bundle for more detailed
     instructions):
     * Download and install JSSE 1.0.2 or later, and put the JAR files
      into "$JAVA_HOME/jre/lib/ext".
     * Execute:
        $JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA
      with a password value of "changeit" for both the certificate and
      the keystore itself.

     By default, DNS lookups are enabled when a web application calls
     request.getRemoteHost(). This can have an adverse impact on
     performance, so you can disable it by setting the
     "enableLookups" attribute to "false". When DNS lookups are disabled,
     request.getRemoteHost() will return the String version of the
     IP address of the remote client.

When trying to accees tomcat-docs via tomcat it works perfectly. But
when I try to get it via apache2 I get a blank page.


I thinks there something wrong with this line :

[channel.un:/usr/share/tomcat4/work/jk2.socket]


That file does not exist. Should I create it ? And how does it has to
be a fifo ? Does anyone knows what is wrong exactly ?

thanks in advance,

Pieter




Here is what I get when I retrieve the status page:
