install the utility called 'screen'  then do the following:

1) ssh in to server
2) run the screen command which opens a 'virtual' screen
3) run the app
4) press CTRL-A-D to detach the screen session
5) log out/close ssh session
6) later on ssh back on to the machine
7) run the command screen -r to reattach the screen session and see whats
up with it

Hope that helps :-)
