Refer to 10.7.3 in the specs
"Every finder method except ejbFindByPrimaryKey(key) is specified in the query deployment descriptor element for the entity."
The findByPrimaryKey method of a cmp entity
bean is fully implemented by the container.
However, ejbql is specified for the other (optional)
find methods declared in the home interface. Also
there are no matching ejbFind methods defined in the
cmp entity bean class for any of the find methods.
A bmp entity bean however would have to provide
data access code using
jdbc and pass sql queries in the
ejbFindByPrimaryKey (or any other ejbFind) method
implementations in the bean class.You dont have to
study bmp entity beans for the exam.
