Hi,
Since I updated my system last week, mod_jk doesn't work anymore. Tomcat starts
up just fine, no errors or warnings. I checked that the AJP1.3 connector runs,
it listens on port 8009. Apache runs fine as well, but as soon as I connect to
the URL I mapped to Tomcat, I get:
"[error] jk_handler::mod_jk.c (2223): Could not init service for
worker=confluence"
I did a few traces and found out that no connection is attempted to port 8009,
so I assume the problem is somewhere in my Apache config. I'm lost for answers
as I couldn't find anything on the web or in my documentation. Can anyone
please point me in the right direction?
This is my configuration:
Linux (Debian Lenny, i386)
Tomcat 5.5
Apache 2.2.6
mod_jk 1.2.25
Fine.
What's your platform (OS)?
Here's my workers.properties:
---- BEGIN workers.properties ----
worker.list=confluence
worker.confluence.host=localhost
worker.confluence.port=8009
worker.confluence.type=ajp13
Very basic, but OK.
---- END workers.properties ----
I configured mod_jk to log as much as possible. This is what it logs (from startup to
"Internal server error"):
What do you mean by "Internal server error": this string is not shown
here. Is there anything in the Apache error log?

this dump doesn't show any lines, which assure, that workers.properties
got found and read. Usually it should dump the contents of the
workers.properties in debug log level.
You should find lines close to the following:

Apache is pointed to the workers file in the load/config file for mod_jk, so it's outside
the VirtualHost. As I see the name "confluence" in the mod_jk.log, I assume
Apache parses it when it starts up.
How does that file look like? Are the paths OK? Does that file really
get read in?
Any suggestions?
