You've got a worker in mod_jk.conf defined as "ajp13".
The worker defined in workers.properites is called "remote".
They need to match...change one or the other...mod_jk.log is probably
holding a bunch of "can't open worker" messages.

Subject: mod_jk Problem
Hi All,
I am running Apache 1.3 and Tomcat 4.1.12 and am not being able
to link the two via mod_jk. The two are working correctly on their own,
but if I hit http://localhost/examples I get a 404 from Apache
(http://localhost:8080/examples does work). The logs say that
/var/www/html/examples does not exist hence it is obviously not going to
tomcat. My workers.properties files is as shown
# BEGIN workers.properties
#
# Setup for apache system
#
# (optional) make this equal to CATALINA_HOME
workers.tomcat_home=/install/jakarta-tomcat-4.1.12
#
# (optional) make this equal to JAVA_HOME
workers.java_home=/usr/java/j2sdk1.4.1_01
#
ps=/
worker.list=remote
worker.remote.type=ajp13
# Definition for Ajp13 worker
#
worker.remote.port=8009
# change this line to match apache ServerName and Host name in
server.xml
worker.remote.host=localhost
#
# END workers.properties
The mod_jk.conf is auto-generated and is as dollows:

<!-- A "Connector" represents an endpoint by which requests are
received
and responses are returned. Each Connector passes requests on
to the
associated "Container" (normally an Engine) for processing.
By default, a non-SSL HTTP/1.1 Connector is established on port
8080.
You can also enable an SSL HTTP/1.1 Connector on port 8443 by
following the instructions below and uncommenting the second
Connector
entry. SSL support requires the following steps (see the SSL
Config
HOWTO in the Tomcat 4.0 documentation bundle for more detailed
instructions):
* Download and install JSSE 1.0.2 or later, and put the JAR
files
into "$JAVA_HOME/jre/lib/ext".
* Execute:
%JAVA_HOME%\bin\keytool -genkey -alias tomcat -keyalg RSA
(Windows)
$JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA
(Unix)
with a password value of "changeit" for both the certificate
and
the keystore itself.
By default, DNS lookups are enabled when a web application
calls
request.getRemoteHost(). This can have an adverse impact on
performance, so you can disable it by setting the
"enableLookups" attribute to "false". When DNS lookups are
disabled,
request.getRemoteHost() will return the String version of the
IP address of the remote client.

Persistent
Sessions.
saveOnRestart: If true, all active sessions will be saved
to the Store when Catalina is shutdown, regardless of
other settings. All Sessions found in the Store will be
loaded on startup. Sessions past their expiration are
ignored in both cases.
maxActiveSessions: If 0 or greater, having too many
active
sessions will result in some being swapped out.
minIdleSwap
limits this. -1 means unlimited sessions are allowed.
0 means sessions will almost always be swapped out
after
use - this will be noticeably slow for your users.
minIdleSwap: Sessions must be idle for at least this long
(in seconds) before they will be swapped out due to
maxActiveSessions. This avoids thrashing when the site is
highly active. -1 or 0 means there is no minimum -
sessions
can be swapped out at any time.
maxIdleSwap: Sessions will be swapped out if idle for
this
long (in seconds). If minIdleSwap is higher, then it
will
override this. This isn't exact: it is checked
periodically.
-1 means sessions won't be swapped out for this reason,
although they may be swapped out for maxActiveSessions.
If set to >= 0, guarantees that all sessions found in
the
Store will be loaded on startup.
maxIdleBackup: Sessions will be backed up (saved to the
Store,
but left in active memory) if idle for this long (in
seconds),
and all sessions found in the Store will be loaded on
startup.
If set to -1 sessions will not be backed up, 0 means
they
should be backed up shortly after being used.
To clear sessions from the Store, set maxActiveSessions,
maxIdleSwap,
and minIdleBackup all to -1, saveOnRestart to false, then
restart
Catalina.
