hi all
According to the section 10.6.4 of the EJB 2.0 Specs, the return type of ejbCreate method of a CMP enity bean is the primary key type of the bean. The primary key field cannot be a primitive type, so that means that ejbCreate cannnot return a primitive type.
However, I have seen examples in which ejbCreate returns the int return type. Also void in some cases.
Can someone please comment on this ?
Thanks
Vipin

Hello,
I can hardly believe that ejbCreate can return primitive, because it must return anything which is child of java.lang.Object.
NOTE, CMP beans should actually return "null" in ejbCreate, and BMP "real" PK.
about "void" return type for ejbCreate - this is signature for session beans, not entity beans.

hi
Thanks for your reply. I wanted to be sure, because I have seen some wrong examples with int as return type of ejbCreate.
Just saw your SCBCD study guide. Really good work you have got here.
Congrats !

Thanks, Vipin
It's not finished yet. Work in progress.
Hopefully in 1..2 weeks it will be done.

The return type cannnot be void, final or static for CMP Entity beans.
And the return type must be the primary key class (String, Object, compound)
However the actual return value is null.
 
It is sorta covered in the JavaRanch Style Guide.
