?I'm trying to setup YAAC to autostart when my pi boots up. I just watched KM4ACK's video and he started Xastir in crontab, so I tried the same with YAAC. I think it's starting, but not attached to my user/screen. I suspect it's because it's a Java app and not stand alone? Any Linux gurus know how to do this right?

my crontab file contains:

#start YAAC at reboot

@reboot sleep 60 && java -jar /home/pi/YAAC/YAAC.jar

?

I tried just hitting the YAAC script but that didn't seem to start it at all. Doing the Java command, with a ps query I can see:

pi@packetpi:~ $ ps -aux |grep YAAC

but there is nothing on the screen.
