how to call or read jar file on the web server for my computer..?

The jar file that I have is supposed to be working with web UI properly with the port number :8080 (which I manually set for local host) when I have it in my computer. However, once it is on the server, it is not working or I don't know how to. Can anyone advise me to have it work properly? html codes for make it work or any kind of codes would be very appreciated.
