Is their an equivalent to Strut's PlugIn?

[Paul Spencer]

I am using Plugins in Struts to startup and shutdown services.  How 
would I do this in MyFaces version 1.1.3.

As an example:
1) When Tomcat is started, the service registers itself with a back-end
   application server. In Struts, this is done in
   PlugIn.init(ActionServlet, ModuleConfig)
2) When Tomcat is shutdown, the service unregisters itself from the
   back-end application server. In Struts this is done in
   Plugin.destroy().
