Ok so first of all sorry for a rather poor title, I'll try to make up for it in the description. Secondly, bear in mind I am no sysadmin and I'm a complete noob.
So here's the story: I just setup an EC2 amazon cloud, installed there one of the Ubuntu (10.10 32bit) AMIs, postgresql and java. Then I started tomcat and my j2ee application. All works fine and dandy but the only way I can access my webapp through the browser is by typing in:
http://ec2-XXX-XXX-XXX-XXX.eu-west-1.compute.amazonaws.com:8080/
And I'd want to be able to do something like:
http://myCustomDomainName.com
And then I'd be forwarded to my webapp in the cloud. Where should I look for that? In tomcat xmls? Somewhere in the amazon ec2 configuration?
