J2EE confusion in EJB Docu example!

Question

I installed the j2ee beta and following the track in the documentation to learn EJB. the sample works fine. But after observing the interfaces and EJB class, I got confused by the following facts:
1. the EJB class ConverterEJB does not 'implements' the remote interface Converter, although it does implement the two methods defined in that interface: dollarToYen() and yenToEuro()
Q: then who 'implements' Converter?
2. EJB Home ConvertEJB defines a single method create(),
Q: where is it implemented.
I can imagine sth between the EJB and its container must be doing sth, but it seems very foggy for me.
Can any expert clarify this a little bit?
thank you

Answer 1

Each session bean has a home interface, a remote interface and an implementation class.
In your case, that is probably ...
ConverterEJBHome is the home interface - it defines all the create() methods that can be used to establish the bean
ConvertEJBSession is the remote interface that defines all the methods on the bean that the client can call
ConverterEJBBean is the implementation class which contains all the create() methods and all the remote methods
