java.lang.Object

org.apache.commons.modeler.mbeans.SimpleRemoteConnector

public class SimpleRemoteConnector
extends Object

Based on jk2 proxy. Proxy using a very simple HTTP based protocol. For efficiency, it'll get bulk results and cache them - you can force an update by calling the refreshAttributes and refreshMetadata operations on this mbean. TODO: implement the user/pass auth ( right now you must use IP based security ) TODO: eventually support https TODO: support for metadata ( mbean-descriptors ) for description and type conversions TODO: filter out trivial components ( mutexes, etc )
