How do I expose a webapp on :8090, even though firewall allows only :80 and :22

Question

I am a noob in Server related stuff, so bear me.

I use amazon webservices (EC2) on which I have a webapp running on jetty, which runs on port 8090. I deploy the webapp through the usual method of

java -jar start.jar

So then to access the app, I have to add a port in the URL, like this:

someIP:8090/app

But just typing someIP in the browser takes me to a page that shows

It works!

This is the default web page for this server.

The web server software is running but no content has been added, yet.

which I assume is apache. I have apache, tomcat and jetty installed. What can I do so that I dont have to specify the port? Do I have to perform port-forwarding?

Thanks a lot.

Look into something like mod_jk. It will allow you to connect an Apache instance to a JAS running on a separate port. Or, you could just setup Jetty to use port 80...

i used iptables,but in your opinion, what is a better method, iptables or mod_jk? – theTuxRacer Dec 29 '10 at 12:25
I think almost everybody would recommend `mod_jk`, if only because mucking with its configuration is not a system level action. Plus, it gives you more control over port 80--you now have full access to port 80 and can forward specific contexts, instead of EVERYTHING on port 80. – Andrew M. Dec 29 '10 at 21:21

The jetty guys have a pretty good page on running jetty on port 80, or using iptables to redirect traffic from port 80.

I dont have a ../extras folder! – theTuxRacer Dec 29 '10 at 11:16
Fine, try their iptables redirect instructions instead, then. – MadHatter Dec 29 '10 at 15:33
