Hi All,

I am new to EJB. I am following EJB 3 in Action Book. Talking about Action Bazar example

In the stateless bean client if we put

@EJB
private PlaceBid placeBid;

It injects the instance of PlaceBid EJB. But in the PlaceBid Stateless session bean code we have only the interface for PlaceBid not the PlaceBid class.
It injects the instance of PlaceBid EJB - means
will the server creates a class which implements the PlaceBid interface?

He's saying that this is explained in the EJB 3.0 specification, which is developed under JSR 220 (JSR = Java Specification Request). Google for "jsr 220"; the first link that comes up is where you can download the specification. It's a good idea to keep the spec handy while you learn EJB.
