installing googlesitemapgenerator on apache(front end) tomcat( backend) scenario

[GoogleCodeExporter]

What steps will reproduce the problem?

I have a site I' using
httpd-2.2.3-65.el5.centos as front end
apache-tomcat-6.0.37 as back end.

I use Mod_Jk connector to connect httpd and tomcat
This is my mod_jk apache config file

cat /etc/httpd/conf.d/mod_jk.conf
JkWorkersFile /etc/httpd/conf.d/workers.properties
JkLogFile /var/log/httpd/mod_jk.log
JkLogLevel info
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkRequestLogFormat "%w %V %T"
JkMount /* worker1
JkShmFile  /etc/httpd/logs/jk-runtime-status

This is my worker.properties file:
cat /etc/httpd/conf.d/workers.properties
workers.tomcat_home=/usr/share/apache-tomcat-6.0.37/
workers.java_home=/usr/java/default
ps=/
worker.list=worker1
worker.default.port=8009
worker.default.host=localhost
worker.default.type=ajp13

I have installed Google Sitemap Generator and gave me final result 
Google Sitemap Generator daemon successfully started.
To start the Google Sitemap Generator module in Apache, you must restart Apache.
After you restart Apache, you can go to http://<this-server-address>:8181/ to
configure the application.
Google Sitemap Generator (Beta) was successfully installed.

But the problem is I can not access mydomain:8181 because of my 
httpd-mod_jk-tomcat settings.
Can anyone say where I went wrong? 

What is the expected output? What do you see instead?
The site is not working in port :8181 it is redirecting to default tomcat

What version of the product are you using? On what operating system?
Linux centos 5.4 32 bit, sitemap_linux-i386-beta1-20091231

Please provide any additional information below.
is it possible to install this in apache-apache tomcat scenario? do you have 
any writeup or tested before? 

I'm not getting any error logs.
I can see originial httpd running on port 80
sitemap on 8181
and tomcat on its ports
but I'm not able to open the manager in browsers. 
Its giving a blank page.
