First, if you can't use the default port, why 80/http, and not 443/https?
You REALLY want it to be secure, and that's the least you can do.

Second, I know nothing about it, and I don't know what it's written in (is
it tomcat?) - but at any rate, I'd assume there is a configuration file
for the application itself that sets that.
