Hello Andre Warnier,
Thanks for the response.
2) tell us what the platform is (O.S.)

3) in the configuration of Apache httpd, there must be configuration lines =
starting with "Jk......".=A0 Copy them here.

Allright, so now we may start getting an idea of the problem.
Maybe the first things to do :
1) do not post files as attachments in this list. Mostly, the server strips=
them.
Instead, if we ask you for some text information, do a copy-and-paste, and =
paste the content directly in your email to the list.
Also, when you copy contents of files here, please remove the comments, and=
any private information such as internet hostnames or passwords.
2) tell us what the platform is (O.S.)
3) if you can, also tell what exact version of the mod_jk moduile you are u=
sing. You should be able to find this in the message that Apache httpd prin=
ts in its error log when it starts.
3) in the configuration of Apache httpd, there must be configuration lines =
starting with "Jk......".=A0 Copy them here.
4) copy here the full content of the "workers.properties" file (comments re=
moved)
5) in the Tomcat conf/server.xml file, there is a <Connector> element with =
a protocol=3DAJP.
Copy this <Connector> element here.
6) if the platform is Unix/Linux, execute the following command and copy th=
e result here :
apache2ctl -V
7) if the platform is Unix/Linux, go to the "bin" directory of Tomcat, exec=
ute the command "version.sh" and copy the result here.
With the above, we will get a much better idea of your configuration, and o=
f what to ask next.
