You really need to learn how shell quoting works. Double quotes doesn't
do what you seem to think. This: "" is an start quote and then an end
quote.
1: Why export APP_ARGS? Almost certainly not necessary.
2: You seem very fond of curly brackets. Also usually not necessary and
IMHO harder to read.
3: What happens if you do this?
$SSH_CMD $host "$APP_ARGS -Dfoo=$host -Dfoo=$host com.packahe.AppClass >/dev/null &"
However it seems to me you have $APP_ARGS but no "$APP" to put in
front of it.
Cheers,
