Need help with javax.jnlp.SingleInstanceService

I have a Swing application (using Java 5) that is launched via Web
Start and I am trying to use the javax.jnlp.SingleInstanceService so
that there is only one instance of my application running and so that I
can pass new parameters to it whenever the user attempts to launch
another instance. Unfortunately I can't get a sample to work and the
documentation is sparse. Can anyone who has used this service provide
guidelines or sample code?

Thank you,
Steve A.

Lazy, is it?*

ingleInstanceService>

It looks pretty straightforward. What's missing?

* You might put up** a simple, 30 line example
for us to test, which will provide information that
is a lot more specific and useful than 'it does not
work'.

** 'Up' as in, on the net, where all those handy little
URL's are, as opposed to on your home PC, on which
we cannot test.
