How to run ODK Aggregate on a port different from 8080?

Hi again,

Don't know if my previous entry got posted since I wasn't logged in to
Google:

I've got Tomcat 6, MySQL running neatly on CentOS 6.5. Everything is hunky
dory, neatly that is.

Tomcat has to run on port 8083 as my ISP Telstra has "stolen" port 8080 on
the Router/Modem and I have got no way to change it.

Configured Tomcat to run on 8083, working nicely. But the ODKAggregate
applications does not like it, any way of changing this?

Thanks.

Kind regards,
Annie
