I *just* completed a successful configuration of Apache 2.0.40 and Tomcat 4.0.4 using the mod_jk.so connector (provided by John Turner, thanks John) on RedHat Linux 7.3 where Apache and Tomcat are running on separate machines.
If Apache is not connecting to tomcat, then you should look on the Apache
box for the cause (assuming that the Tomcat box is running! <g>).
In your httpd.conf file, there should be two directives, JkLogFile and
JkLogLevel. Set the JkLogLevel value to "debug" and restart Apache. Then
when you make a request, you should be able to see what is happening via the
log file.
Note: If you followed John's instructions for configuring the system, you
will have a problem because those instructions depend on the Tomcat listener
(ApacheConfig) to generate the mod_jk.conf file. This won't work if tomcat
and apache are on separate boxes, so you'll have to do that part manually
(or copy the generated file from the tomcat box to the apache box).
If your httpd.conf file contains this directive:
include /usr/local/tomcat/conf/auto/mod_jk.conf
then you will have problems, because tomcat is not on the apache box.

Even though I didn't copy, Atleast Apche should have connected to tomcat and
I should have executed jsp pages existed on tomcat box, here apache is
serving some static files which are existing on apache boxe, but when I
tried to execute http://www.xxx.com/examples/(in mod_jk.conf jkmount
/examples/* ajp13) it is supposed to connect to tomcat box and execute
jsp's, but it is not recognising them, because it is not even connected to
tomcat

If you want to put Apache and Tomcat on separate boxes, and still run the
Tomcat examples, you will have to copy the static (.html) files from the
tomcat box to the apache box so that apache can serve them.

The lines like "tomcat_home" etc. in workers.properties are optional.
(thanks Milt!) You only need the worker definitions (like port number,
etc).
I'm not sure about the Alias /manager question, that is a good question.
You don't need mod_jk.so on the Tomcat box, its an Apache module.
