Timeout Service in SAP WAS 6.40

Question

Howdy,
I am currently in the process of migrating our enterprise application from Jboss 3.2.6 to SAP WAS 6.40.
In Jboss we have a standard Timer Service and our application class registers as a Listener to the Timer Service listening for notifications at regular intervals and I am trying to implement a similar mechanism in SAP WAS.
Came across a few options
1.To implement the JMX standard Timer mbean as a service and deploy it into SAP WAS so that it is deployed and automatically starteed and then to write a notification listener to this service - Now came across a post that suggested that this is not possible in 6.40 since deployment of custom services is not supported - not sure if it is still possible though
2. Second option is to use the Timeout service in SAP WAS itself but having huge problem in implemnting the listener to this service. First of all i had a problem locating the jar that contained the com.sap.engine.service.timer package, after having doen that <b>i now face the hurdle of finding the file containing the com.sap.engine.frame.container.event package.</b>
Documentation certainly ain't very useful.
Any help from anyone who has attempted to do a similar thing is much appreciated.
Thanks
Dushy

Fantastic, thanks Nathan. Will try that, i m trying to deploy my mbean from a servlet at the moment as that seems to be a preferaable option among the group here.
Having problems getting the servlet load at startup. My understanding is that the servlet should execute the code in the init() method as sooon as i deploy the application to SAP WAS.
My Web.xml looks as follows:
