Class J2EEControllerManager

java.lang.Object
  org.opensubsystems.core.logic.ControllerManager
      org.opensubsystems.core.logic.J2EEControllerManager

public class J2EEControllerManager
extends ControllerManager

Class responsible for instantiation of j2ee controllers. This class determines what controller should be used based on currently used component model, creates the j2ee controller instance if it wasn't created yet and caches created instances. This of course assumes that the j2ee controllers are implemented to be stateless and reentrant.
