Updating client gui with session beans ejb Free israel sex chat room
Every method call made to the business service object, be it an entity bean or a session bean, is potentially remote.Thus, in an Enterprise Java Beans (EJB) application such remote invocations use the network layer regardless of the proximity of the client to the bean, creating a network overhead.
The client container efficiently and transparently localizes certain parts of an EJB-hosted application into a client framework, where it can be easily accessed by the client application, and later re-persisted to the hosting EJB container.This approach is getting a bit limited though as i want forms to react on changes it makes, and i think the best way to handle this to propagate the changes from the domain layer.For this approach i have to equip the domain objects (ie the EJB3 entity beans) setters with fire Property Change operations.Would this be a good design choice or is it not-done to implement entity beans like this ?
thanks a lot in advancei'm not thinking of specific GUI code (like building frames, or accessing swing components directly, ...) in my entity beans.
The Session Facade pattern has been clearly described in a number of places, namely [Sun 2001] and [Brown 2000].
