Running java application - unable to detach screen
I started using Linux again because me and my friends wanted to host a Minecraft server. After finding a sponsor, I configured and installed the Minecraft server, which is a java application.
I start the server with this command:
java -Xms1G -Xmx1G -jar minecraft_server.jar nogui
After this, the server starts without a problem. I get into a console, where I can save, quit the server, ban players, etc. This console is run in the screen application. When I close Putty now, so does the Minecraft server. I need to find a way to detach the screen.
After some googling, I found that I this is done by using Ctrl+A and then D to detach. For some reason, this does NOT work in my case. It just shows up as ^Ad. Ctrl+D shows up as plain text, ^D in my console. I cannot exit the console, nothing happens.
Any solutions to this problem? Thanks in advance!
