HFEJB: Coffee Cram Entity Beans

[Greg Charles]

In the Coffee Cram for Chapter 6 (page 367), question 1 reads:

What's true for a bean provider when creating an entity bean using container-managed persistence.

Answer D is not marked as a correct answer:

D. Accessor methods for container-managed relationship fields must be exposed in the bean's remote component interface.

First, the question comes a chapter too early. Chapter 7 covers entity relationships. Still, it seems like D should be correct. Why isn't it?

Hi,

To make a relationship, we need entity beans with local relationship.
So you cannot pass local interface to clients through remote interface. (i.e) remote clients cannot get local component interface

So CMR field should not be exposed to client in remote component interface.
Hope it helps.

Micheal.

Ah, that's it! Remote is the key word. I was looking at the word "expose" and trying to figure out if the trick was in there. Thanks Micheal.

Hello Friends,
I am wondering then how does one use CMRs with remote entity beans? How can I call methods on remote entity beans to get related entity beans when they are not even present in the remote interface?

Salil,

CMRs cannot be used with remote client view.
