Multiple Java webapps with different domain names to be hosted on AWS

I am new to AWS and am running an instance of Bitnami tomcat on my EC2 machine.

I have 2 different web apps namely webapp1 and webapp2 i wish to have two different domains point to each of the web apps

I have an elastic ip associated with my ec2 instance.

what i wish to achieve is domain1.com to be serviced by ec2-aws.com/webapp1 and domain2.com to be serviced by ec2-aws.com/webapp2

what changes should i do to my dns configurations

my domains are registered at goddady.

just an 'A Name' record change in the DNS file is landing on the bitnami tomcat page and not on the web app i wish to access

TIA
