you cannot instantiate an interface. Hence forth you implement the methods in those interfaces in your home and remote interfaces by extending them. Again the EntityBean is not an abstract class but an interface. Hence your bean class makes use of its methods by implementing them.

hope the explanation helps!!
let me know if not clear....

it is upto container which instantitates and maintain all entity bean in the ejb container.
But to act like a entity bean,the developer has to implement EntityBean and all abstract methods defined in it.
This is not in the case of EJB3.0 where all those abstract methods implemented by default behind the screen,since we use annotation to intimate to the container
 that the class is going to act like EntityBean or going to represent the row in table.

Clients never dealt with direct instances of Entity Bean. It deals with container implementations of home and component interface (stubs & skeletons - aka deployement code)

It is the container responsibility to Wrap a class around the abstract definition of Entity bean.
