Head first EJB question

[Bin Lu]

P. 672 Q.45 which methods from EntityContext interface can be invoked, regardless of transaction context?
A. getEJBHome()
B.getEJBObject().
I remember in ejbCreate(): disallowed to call getEJBObject?
Any comment?

[Vishwa Kumba]

getEJBHome() can be called.
But getEJBObject() and getPrimaryKey() methods cannot be called in the ejbCreate() methods of entity bean.
