Hi !
Can anyone tell me why the specification does not allow object inheritance of entity beans ?
Why can't a employee entity bean not make use of an exisiting person entity bean ?
Is it true that some vendors use pass-by-reference semantics to optimize local calls although the specification stipulates pass-by-value semantics ?
It is sorta covered in the JavaRanch Style Guide.
