RE: Problems with Mod JK (Apache 2.052 and Tomcat 5.5.9)
I guess one way to test if the ajp listener on tomcat is working is to
take a look at your Catalina log file and see if it contains a log
message something like "INFO: JK: ajp13 listening on /0.0.0.0:8009".
Some other factors to consider: Are tomcat and apache httpd running on
the same machine? Any firewall/proxies/socks in between?

I tried your version and I tried deleting acceptCount and className out
of
the connector settings and nothing has changed. I am still getting the
Error
500, when trying to access "server.domain.com". Other apache only
virtual
domains work without problems.
The error log still says :

What else could it be?
Thanks,

I see. It still looks like a connector configuration problem. It seems
that your connector config was using an older format, not the one for
5.5. For instance, the acceptCount and className shouldn't be part of
the AJP connector setting.
You may want to try the one I posted or configure one according to
http://tomcat.apache.org/tomcat-5.5-doc/config/ajp.html

Thanks for the assistance Nick.
I think the connector is alreary defined in the current configuration.
Perhaps you overlooked that line :
<Connector acceptCount="128"
className="org.apache.coyote.tomcat5.CoyoteConnector"
connectionTimeout="20000"
debug="0"
enableLookups="false"
minProcessors="32"
maxProcessors="384"
port="8009"
protocolHandlerClassName="org.apache.jk.server.JkCoyoteHandler"
protocol="AJP/1.3"
redirectPort="8443"
useURIValidationHack="false"/>
Should I delete this one and try yours? The same error occured when they
were placed side by side (yours on top).
Thanks for helping.

Well, the log msg is complaining about not able to find the worker.
Apparently your tomcat wasn't configured for listening to ajp13 request
from httpd. A connector entry for ajp13 should be added to server.xml
file. At least it was not listed in your email.
<!-- Define an AJP 1.3 Connector on port 8009 -->

"I remember workers.properties is located in apache/conf/, the same

The file workers.properties is located under Tomcat`s conf directory,
not
Apache`s.
In workers.properties I only have the following and that should be
enough :
worker.list=ajp13w
worker.ajp13w.port=8009
worker.ajp13w.host=localhost
worker.ajp13w.type=ajp13
worker.ajp13w.cachesize=10
worker.ajp13w.cache_timeout=1200
worker.ajp13w.socket_timeout=3600
Any other idea what else it might be?
Thanks for the reply and trying to help.

Since I am a new user of mod_jk, please correct me if I am wrong.
In your apache httpd.conf, you set:
"JkWorkersFile "/var/tomcat/conf/workers.properties"
I remember workers.properties is located in apache/conf/, the same
directory with httpd.conf..
And, do you indicate the location of tomcat in workers.properties, such
as
workers.tomcat_home=/.../tomcat/?

Re: Problems with Mod JK (Apache 2.052 and Tomcat 5.5.9)
Posted by Luka Andrejasic <lu...@gmail.com>.
The Catalina log file does contain the message you suggested. And also
another one listening on /0.0.0.0:8010.
There is only the basic firewall running on the server, with the following
settings :
*filter
:INPUT ACCEPT [0:0]
:FORWARD DROP [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -p icmp -m limit --limit 5/sec -j ACCEPT
-A INPUT -p icmp -j DROP
-A OUTPUT -m limit --limit 2000/sec --limit-burst 2000 -j ACCEPT
-A OUTPUT -p icmp -m limit --limit 5/sec -j ACCEPT
-A OUTPUT -p icmp -j DROP
COMMIT
And yes, Apache and Tomcat are both running on the same server. I really
have no idea what this could be...If I put the mod_jk log into debug mode,
it starts generating a file, which gets a few GB after a few days. And that
is just from 1 connection.
What else could be wrong?
Thanks for helping,
Luka
