EJB Facade basic question

Hi All,

I have a basic question on EJB Session Facade design pattern.

What is the extra code we write in normal Session Bean, to make it as Session Facade.

I never involve in EJB coding, but i know the coding and bit curious to know about it. I see Normal Session Bean coding and also seen Session Facade coding, i dont find any difference in implementation, then y do we call it as a Session Facade design pattern. Are all session beans are by default called Session Facade or do we need to write any extra code in a normal Session bean to make it as SF.

Requesting to clarify.

Thanks & Regards,

Ravi Kumar
