it seems like you should just be using the java.util.Observer/Observable
that are provided with the JDK.  that'd save you a lot of the work of
reinventing the wheel.  plus there must be some decent tutorials out there
on how to use those.

Subject: [Advanced-java] basic event listener code



Hi Friends,

I need sample code in implementing event-listner model (non AWT).

The problem description is like this,

I have an interface declared EventListner (not AWT, just named so). 
This has a method called tell().

There is a SubscriptionListener class which implements this interface. There
is another class SubscriptAcceptor that gets notified by the Subscription
Listener class.

The problem is I should write code which will send a notification from 
SubscriptListener to SubscriptAcceptor. This is  a synchronous 
communication say can be implemented like an event listner model. If I can
get 
some code outline of how to go abt that would do a world of good for me.

Thanks in advance

vishy
