question #5 p292

[Van Nguyen]

b. is true - how come? I see you can use getHandle() to get a handle but I don't see how you can use a handle to get a object ref. I know it must exist or else what good would getting a handle be. I just don't know what method you would call to convert a Handle to and Object ref.
c. is not true - why? can't I call get the object ref from findByPrimaryKey(pk) ?

Following are the methods u can call upon in order to get Object refrences to either yr Home or yr Remote interface.
1)getHomeHandle() method in java.ejb.EJBHome interface returns a javax.ejb.Handle Object.You can call getEJBHome() method on this HomeHandle Object to get a refrence to yr Home Interface.
2)getHandle() in yr javax.ejb.EJBObject interface returns a javax.ejb.Handle Object.You can call getEJBObject() method on this Handle Object to get a refrence to yr Remote/EJBObject Interface.
Hope that was of help to you...
