Another variation of my previous posting (see below) can be expressed as
Is it possible to detect from within a Java app if a Mathematica Kernel
is already running and after that connect to it? If yes, how?
I would enormously appreciate it if somebody could point me to an
example or document that will shed some light on this, or,
alternatively, share his/her experience on the subject.
