ResourceManager

public class ResourceManager extends Object implements com.sun.enterprise.admin.event.ResourceDeployEventListener
Handles resource deploy events. When a resource is updated/added, admin server sends a notification to the server instance. This object is the listener for all resource events. Resource deployers throws UnsupportedOperationException when an operation is not supported and requires a server restart. It catches the UnsupportedOperationException and notifies admin event multicaster with RESTART_NEEDED flag.
