Dear Bob,
I didn't actually uninstall nginx. This is what i did:

1. I ran a2enmod module
2. nano /etc/apache2/sites-enabled/000-default.conf
3. I define a proxy virtual host using mod_virtualhost

<VirtualHost *:*>
    ProxyPreserveHost On

    # Servers to proxy the connection, or;
    # List of application servers:
    # Usage:
    ProxyPass / http://[IP Addr.]:[80]/hris
    ProxyPassReverse / http://[IP Addr.]:[8080]/dhis
    # Example:
    ProxyPass / http://0.0.0.0:8080/
    ProxyPassReverse / http://0.0.0.0:8080/

    ServerName localhost
</VirtualHost>

service apache2 restart

Then i test both application where running. Please let me know if it
makes sense.
NOTE: 0.0.0.0 was replaced by the local server IP
