Hi Everyone! I need some help.

I just downloaded a program called Oulook Messenger that my family uses to communicate. The program uses Java to run on Linux machines and I would like it to start automatically with my computer. I can run it by going to to folder, opening the terminal there, and typing in:
java -jar OutlookMessenger.jar
However when I close the terminal, Outlook Messenger closes too. Is there a way to open this when my computer starts without having the terminal open? Thanks!
