Hi
This is perhaps out of topic, but I have a question about CMP and EJB and
there seams to be some very experiensed EJB-programmers rading this list.
Reading Suns j2ee tutorial it says that an EJB must have a primary key. I
wonder if it is possible to have a EBJ that only have a foreign key. Eg a
weight watchers system with person and weights att diffrent dates:
SQL:
create table person (id int primary key, name varchar(20))
create table weight(fk_person foreign key, date varchar(8), weight numeric)
Say that I have 2 entity EJBs, PersonEJB and WeightBean. The relationship
is 1-n. Must the weight table also include a primary key to make CMP work,
even though a primary key in this table from a SQL-point of view is
unnessesary?
Best regards // Mattias
PS
I am proud to announce that I have got my first test case of a JSP page
calling an EJB to work!
