+1; the Observer/Observable stuff is pre-JavaBeans days .. to do this
just define an interface called
AxisConfigurationChangeListener {
void newServiceAdded (..);
void serviceDeleted (..);
...
}
(or something like that) and have the RSS guys impl that (and register
it thru the mechanism u proposed).
AxisConfiguration will have to have an
"addAxisConfigurationChangeListener" method (and the corresponding
remove method). Just have a vector of listeners and then when something
interesting happens call a method to invoke the proper method of the
listener interface in a loop.
Sanjiva.
