mock exam about isIdentical

[Deep Chand]

For 2 Entity Bean objects with the same primary key but from different homes, will isIdentical() return true or false?

I think it should be false.

You are right.

Sure,

it is like have

PK1 = Integer(1)
PK2 = Integer(1)

PK1 equals to PK2

and

EJB1 = AddressBean (has the PK1 key)
EJB2 = PersonBean (has the PK2 key)

EJB1 is not identical to EJB2.

Mikalai,

Correct but when I said 'same home', I meant same entity bean type i.e. both the objects are of PersonBean but from different homes. I have this doubt because if a bean is deployed twice, each will have a different home.

Please reply.

Both of them must come from same home and should be pointing towards the same entity. By Entity, i mean , Primary Key's object data that uniquly identifies it in the database. For example Bean 1(#88) ,Bean 2 (#88) , Bean 3 (#98), Bean 4(#299) . Consider these are all beans with primary key values in parenthesis. When you run isIdentical on Bean 1 and 2 , it should return true bcaz Bean 1 and 2 are sharing the same primary key object. For all others it will return false. I assume all of them are coming from the same home.
