RE: What is session facade
|
| A SessionFacade acts like a wrapper class which exposes necessary methods of all the beans present in this class , these beans might be entity or session . On calling the method of this class we should write code to call the method on the respective bean i.,e we need to write code that redirects the call to the respective bean which was supposed to handle the request. This class should typpically need to be a remote bean and this shoul act as pont of entry to all other local beans . By this we reduce the network traffic as only once object proxy is being travelled from server to the client. |
