Need help to Setup Server and Deploy War File - For Dummies?
I worked with a freelance developer and he left me hanging with little direction on where to go next.

He created the code in PHP/HTML/JavaScript (I believe) and a server and left me with the code and a WAR file.  He turned off the server so now I need to create it on my own.

He left me with this advice:
"Setup a server, deploy the war file, run the application." - That's verbatim.

I am stuck.  I am a beginner and when I google and research this I come to the conclusion that I can't figure out how to use tomcat or anything to solve my problem and properly build my server. 

I believe I need a RackSpace server? I'm trying to avoid a new developer to come in but I am stuck with no server.  I want the server to be a live environment and not just on my local machine.

Where to start?
