I am trying to deploy a simple start up class at JBoss startup time and it keeps giving the following error:

The TaskTimerStartup class extends ServiceMBeanSupport and implements TaskTimerMBean interface.

I have put both these classes and jboss-service.xml in a sar file and deployed it with my ear file. I also added the following entry to application.xml
