Hi Graham,
Try enabling server-info in the Apache config and confirming that
mod_jk has actually been loaded.
Your "LoadModule" is wrapped in an "Ifdefined" statement, so it's possible
that some of the mechanisms you are using to start apache do not define
"HAVE_JK", and mod_jk module does not get loaded. In your current
configuration, the webserver would need to be started with a command like:
httpd -D HAVE_JK
before your jk module will be loaded.
(you might want to check what exact commands are being used in the system
startup scripts and/or the apachectl script to confirm this)
However, your JkMount statement is not wrapped in any conditional statements,
so it will always attempt to execute this, even if mod_jk is not present
(hence the error).
The simplest solution for you is to probably remove the "IfDefined" wrapper
around your LoadModule/AddModule statements, so mod_jk will always be loaded.
Regards,
Morgan
