Multiple application servers on one droplet

Hello, we are running two application servers(galssfish and apache) on our droplet. We have java application running on glassfish server and wordpress page runing on apache. Glassfish runs on default port(80) and apache on 8079 port. If someone wants to see wordpress content, they have to type 100.100.100.100:8079, so we want to hide the 8079 port. One option could be ip adress as url(100.100.100.100) to enter wordpress and ip adress + /something (100.100.100.100/program) to enter java application. As another option there could be some subdomain like users.100.100.100.100 to enter java application and just ip adress to enter wordpress page. Is it possible to do that? Thanks in advance.
