Don’t know offhand, but if you want to write a banner message just
once, there are various ways of doing it – easiest off the top of my
head is to have a static boolean in the MXJ class which you examine,
and set, in the constructor. (This assumes that object instantiation
is single-threaded.)

Or maybe just have a static block at the top of your class that does
the post…
It will be called once when the class is loaded.

That’s a cleaner solution, but I wasn’t sure whether it was safe to
do post() while a static block is being executed…
