Hi Everybody,

I am very new to EJBs, when i read about SessionBeans, it is mentioned that these performes a task for clients and delegates the request to other components/Entity Beans by hiding the complexity of business logic. So can we call them as Command Pattern implemented here, because it separates the client from the executer of that task.

Please correct me if i am wrong.

Session Beans usually acts as a session facade for entity beans.
