Running a jar file in the background on Linux

| I have a server that's made in Java. However, when I run it I have to keep the console window open which kind of defeats the purpose of running it on a remote server if my computer has to stay on as well. I can run it in the background at least, but the console window my stay up. Is there a way it can run without my console window open? Is making it a service the only way?

| I would probably use screen to do this. Same time ftw.
You can also add the -S parameter to give your screen a personal name.

| How can I do that? It's a .jar file, so I usually start it with java -jar server.jar &

| You don't have to start the program in the screen startup.
For example you could just type screen to start a new session.
Run the jar application like you normally would and then detach the screen.

| Mm...I'm on a mac, so when I did ctrl + a then d, nothing happened. What's that supposed to do? Anyway, it worked.

| Darn you beat me to it
That should work for you Mike - I have used that same method for Java programs that I have run on a shell account.

| I always suggest knowing how to run and compile java and jar programs from the command line, before using a GUI.

| Well, since I'm running this on a server I'm never going to use a GUI.

| You wouldn't need the & if you were running it in a screen, would you?
screen -A -m -d -S screenname java -jar server.jar
Would start it and detach the screen automatically, then type screen -r screenname to get back into it.
