Question 5 from mock exam
public int ejbCreate() throws javax.ejb.CreateException

why above option is wrong?
Return type is int (i.e. valid) for Remote method return type..

However int is invalid to be a PK, recall there is a mandatory element for entity bean in DD -- <prim-key-class>.
As we say that is a "class", so the PK must be an "Object"

More you can think is:
Recall there are 2 remove() from EJBHome, one takes handle and another takes PK as parameter.
If the PK can be int, double, .. etc, I think we may need 8 more remove()
so primitive type is not good to be a primary key

and if you want something close to a primitive type..wrap it up using the wrapper classes and use them as a primary key class ...ans convert it back using the toString() method.
hope this helps
thanks
