Apache virtualhosts not working for subdomain

Question

I am having trouble with setting up a apache server on ubuntu.

I need to have the main domain loading just a website, but a subdomain loading a tomcat server. To acheive this I follwed the instructions here: https://sites.google.com/a/ci2s.com.ar/wiki/technics/how-to-run-apache-httpd-and-tomcat-on-port-80-using-mod-proxy

This didn't work, both the main and the subdomain point to the same folder. I found on serveral answers here that I shoudl include the line NameVirtualHost *:80

However when I restart the apache server i get the follwing warning:

 AH00548: NameVirtualHost has no effect and will be removed in the next release /etc/apache2/sites-enabled/ginl.hodzelmanstechnology.nl.conf:1

Can anybody help me with this?

Some output to help troubleshoot:

Answer 1

You need to define your subdomain in the "VirtualHost" element of your config file, so the server may distinguish between different hosts:

<VirtualHost kantoor.ginl.hodzelmanstechnology.nl:80> 
 ...
</VirtualHost>
