YPService simple example

[Aaron Helsinger]

If you are having trouble with the Plugin concept, you should go back to
the basic tutorials and slides
http://tutorials.cougaar.org/

The pizza app is a fairly simple explanation of Service Discovery. You
should be able to use it as a basis to do what you want -- I would
suggest modifying this code to do what you need.

Details on the data flow in the Pizza application are here:
http://tutorials.cougaar.org/pizza/flow.html

It describes what the Pizza SDClientPlugin is doing -- hopefully enough
that you can avoid trying to fully understand the SimpleSDClientPlugin

You may simply be able to extend the pizza party app to do your thing.
Try looking at these docs:
http://tutorials.cougaar.org/pizza/extending.html

The slides that walk you through the configuration files of the Pizza
app should help too:
