4  * Implementation class for the Student bean.
5  *
6  * <p>Each instance of StudentBean
7  * maps to a table entry of "one2many_students", where student is defined.
8  *
9  * <p>StudentBean is abstract since it's taking advantage of container-managed
10  * persistence. Resin-CMP will create the implementation of the abstract
11  * methods.
12  *
13  * <p>StudentBean also takes advantage of the AbstractEntityBean
14  * implementation. AbstractEntityBean is just a stub
15  * EntityBean implementation with default methods to make life
16  * a little more sane for simple beans.
17  *
18  * <p>This CMP bean uses the following schema:
19  *
20  * <code><pre>
21  * CREATE TABLE one2many_students (
22  * name VARCHAR(250) NOT NULL,
23  * house VARCHAR(250),
24  *
25  * PRIMARY KEY(name)
26  * );
27  * </pre></code>
