the class CmpJpaConversion method mapClass2x.

/**
 * Generate the JPA mapping for a CMP 2.x bean.  Since
 * the field accessors are all defined as abstract methods
 * and the fields will not be defined in the implementation
 * class, we don't need to deal with mapped superclasses.
 * All of the fields and concrete methods will be
 * implemented by the generated subclass, so from
 * a JPA standpoint, there are no mapped superclasses
 * required.
 *
 * @param mapping     The mapping information we're updating.
 * @param bean        The entity bean meta data
 * @param classLoader The classloader for resolving class references and
 *                    primary key classes.
