--- Comment #4 from Vladimir Mikhelson <vlad@hollebcons.com>  2009-05-17 20:15:32 PST ---
Guenter,

I went ahead and downloaded the latest 1.2.28.

First, I verified that mod_jk v.1.2.23 was running 2 times, in address spaces
"os" and "adminsrv" respectively.

Then I shut down all instances of Tomcat and both instances of Apache by
issuing the following commands:
tcadmdn
tc4stop
tc5stop
ap2webdn
unload address space = adminsrv apache2

Then I verified that mod_jk.nlm was not loaded.

After that I issued ap2rsall. The following messages were displayed in the
Apach 2.0.63 for Netawre screen:

[Sun May 17 21:10:27 2009] [warn] module rewrite_module is already loaded,

[Sun May 17 21:10:27 2009] [warn] module jk_module is already loaded, skipping  
Syntax error on line 638 of SYS:/apache2/conf/httpd.conf:                       
JkWorkersFile only allowed once                                                 
<Press any key to continue...>

The following messages were displayed in the Apache2 Web Manager screen:

Apache/2.0.63 (NETWARE) mod_jk/1.2.28 PHP/5.0.5    
   Running in address space ADMINSRV               
   Listening on port(s): 2200 2211                 
   Loaded dynamic module mod_jk.c                  
   Loaded dynamic module mod_headers.c             
   Loaded dynamic module mod_rewrite.c             
   Loaded dynamic module sapi_apache2.

Please pay attention, normally the "Apache2 Web Manager screen" is hidden,
prefixed by the "*" before the screen name in the screen list. This time it was
not.

After pressing "any key" in the first of the two screens I verified mod_jk.nlm
v1.2.28 being loaded once in adminsrv address space.

All attempts to start Apache in address space OS failed.

Please verify that you can reproduce the behavior I describe.

System details: NetWare 6.5 SP8, Small Business Suite. Runs GroupWise 8 HP1
with WebAccess.

As far as your request to analyze all includes in httpd.conf goes this is what
I discovered.

Include "SYS:/qfsearch/WEB-INF/QFSrchApache.conf" is issued in the httpd.conf.

QFSrchApache.conf contains the following code:

    #########################################################
    # Make sure Apache - Tomcat connector is loaded
    #########################################################
    Include "SYS:/qfsearch/WEB-INF/QFTomcatConnector.conf"

QFTomcatConnector.conf" contains:

     <IfModule !mod_jk.c>
        LoadModule jk_module modules/mod_jk.nlm
        JkWorkersFile "sys:/adminsrv/conf/mod_jk/workers.properties"
        JkLogFile "logs/mod_jk.log"
        JkLogLevel error
    </IfModule>


Please let me know if you need more details.

Thank you,
Vladimir
