I'm trying to connect the Apache WebServer (2.4.10) to Tomcat 7, both located in two different VMs. It's my first time using those tools. From what I understood a method to check if the connection is working is to try to access to Tomcat using the URL IP/instance instead of, if I have Tomcat on the 8080 port, IP:8080/instance. However, everytime I try to do that, a 404 error is returned by Apache. Here's my configuration:

On the Tomcat's VM, server.xml has the line:

<Connector port="8009" protocol="AJP/1.3" redirectPort="8443 />

On the Apache's VM, I have set those files:

apache2.conf (in the Apache main folder)

Servername apache
Include httpd.conf
ServerRoot "/etc/apache2"

Mutex file:${APACHE_LOCK_DIR} default

PidFile ${APACHE_PID_FILE}

KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 5

User ${APACHE_RUN_USER}
Group ${APACHE_RUN_GROUP}

HostnameLookups Off

ErrorLog ${APACHE_LOG_DIR}/error.log

LogLevel warn

    JkMount jk-status
    Order deny,allow
    Deny from all
    Allow from 127.0.0.1
</Location>
<Location /jk-manager>
    JkMount jk-manager
    Order deny,allow
    Deny from all
    Allow from 127.0.0.1
</Location>

I know it can be a mess because I tried following different guides and doing everything to have it working but I still get 404 errors. How can I have it working?

For some reasons, it started working once I tried (in the desperation) to implement a load balancer even without the AJP connector working on the single server, given that this was from the beginning my final goal. Ultra happy.

At the end I also wrote the JkMount instructions in the 000-default.conf file in sites-enabled, precisely in the VirtualHost< *:80> istruction. Maybe this was needed in order to work properly.
