Java Event mechansim

The project is to build event mechanism (From scratch or utilize existing open-source project) with the following functions:

* The events should be defined in a central place (i.e. central event list)

* Event should be raised from a class with a reference to relevant object (Event relevant data).

* Objects can listen on events (register on event). The registration should be either in the listener class or in central place, where all events & listeners are mapped.

* An object can listen to more than one event.

* The mechanism should be able to invoke the listeners with the corresponding event name + relevant data object.

* The listener should have a basic life-cycle, that indicates the listener completion status.

Each life cycle status is actually an Event the will trigger a corresponding action:

- OK (do nothing)

- Retry (Should re-invoke the listener up to 4 times)

- Failed (Log failure)

* Event invocation should be decoupled and asynchronous.

The solution should be *Simple*, scalable & robust.

The mechanism will be used in the following environment:

JDK 6, Ubuntu, Tomcat 6

Habilidades: J2EE, Java
