Start with an Ubuntu AMI. Then install tomcat. Now put the WAR file of your J2EE app where tomcat can see it. You can use the AWS console to start/stop your machines, configure firewall rules that allow you to access port 80, etc. There won't be a step by step guide telling you exactly what to do, welcome to being a programmer.
