Question: Can the primary key in the entity bean be a Java primitive type such as int?Answer: The primary key can’t be a primitive type–use the primitive wrapper classes, instead. For example, you can use java.lang.Integer as the primary key class, but not int (it has to be a class, not a primitive). |
