public abstract class SubDeployerInterceptorSupport
extends InterceptorServiceMBeanSupport
implements SubDeployerInterceptorMBean

Base class that can be used for writing services that dynamically hook to other interceptable deployers in order to add functionality in the deployment cycle. We override attach() to install a different interceptor from that of the base class that understands SubDeployer calls. Note that the baseclass invoke(Invocation) won't be called, so no need to override it. Simply call attach()/detach() from createService()/destroyService() or startService()/stopService() pair methods to attach/detach the interceptor to the configured Interceptable SubDeployer(s). Then override any of the init/create/start/stop/destroy methods to apply the extra interception functionality. Inside those methods don't forget to forward the call using invokeNext().
