Effects of the previous enterprise models to Gateway(1)
We adopted the JavaBeans event model and removed the requirement of addXlistener/removeXListener method pair to add/remove event “X”. Event connection is handled by Gateway context
We took off the requirement of setX/getX method pairs for attribute “X”. We get the attributes from XML document generated from IDL file of user module automatically.
As opposed to JavaBeans persistency of classic java serialization model, we serialize our objects in XML.
