You need to create a primary key class for your EJB. The class needs to
have public members representing the elements of your key. It needs to
implement the java.io.Serializable interface, and it needs to implement:
public boolean equals(Object obj)
and:
public int hashCode()
You specify this class (fully qualified) as the <prim-key-class> in
ejb-jar.xml. You do not specify a <primkey-field>.
