i am reading the 'core j2eepatterns'. a question on the pattern of Session Facade. quote the original text from book following:
"A Session Fa�ade is implemented as a session bean and interacts with business components, such as Business Objects (374) and Application Services (357). "
as the interpretation of Business Objects, my understanding is somthing like entity bean those persistent component. also the applicatoin services is another type of 'session facade' except that it is POJOs. if so, Session Facade is an encapsulation for persistent component like ejb. my doubt is, does a session facade can encapsulate a session bean? is it encouraged to do so? or i make a mistake? help.

lso the applicatoin services is another type of 'session facade' except that it is POJOs.
Application Sevice could be ejb (slsb or sfsb)
Session Facade is an encapsulation for persistent component like ejb
Session Facade encapsulate access to system logic for clients For example Client -> SessionFacade -> ApplicationService -> entity Bean or simply Client -> SessionFacade -> entity Bean
