what you need to do is run rfcomm from within a shell script and
invoke the shell script from java :

gksu rfcomm connect 0 0B:D4:91:39:66:01 &
lastpid=$!
echo "${LASTPID}

$! - returns the pid of the last forked process which in this case is
the rfcomm process ...

to check if its still running you can use pgrep or pipe-filter ps -ax ...
