in the section “Implementing Your Plugin”
“You can store persistent plugin settings as Wildfire properties using the JiveGlobals.getProperty(String) and JiveGlobals.setProperty(String, String) methods. Make your plugin a property listener to listen for changes to its properties by implementing the org.jivesoftware.wildfire.event.PropertyEventListener method. You can register your plugin as a listener using the PropertyEventDispatcher.addListener(PropertyEventListener) method. Be sure to unregister your plugin as a listener in your plugin’'s destroyPlugin() method.”
the interface +PropertyEventListener" should be ‘‘org.jivesoftware.util.PropertyEventListener’’
