Restrictions for the CMR fields

[Poo Kan]

HFE says ..
"The restrictions for the CMR fields are that they can refer only to the local component interface of the entity bean,and....."

Pleas explain why it can not refer to a remote component interface?

This is the nature of CMR among entity beans, i.e., it is designed so. I guess the advantage of having local relationsip scope is that we can have better performances rather than remote relationships.

For more information, please refer to the EJB 2.0 Specifications, page 131, section 10.3.2.

I guess with local references itz easy to maintain the relation object map.
Something what hibernate does.

With remote references one major thing is how will you verify if the object is still there ?
that is avoided by local references as the object map is maintain in single heap.

I guess my guess is pretty much on the mark.

Please confirm
