 <div class="block">Specifies a single-valued association to another entity class that
  has many-to-one multiplicity. It is not normally necessary to
  specify the target entity explicitly since it can usually be
  inferred from the type of the object being referenced.  If the
  relationship is bidirectional, the non-owning
  <code>OneToMany</code> entity side must used the
  <code>mappedBy</code> element to specify the relationship field or
  property of the entity that is the owner of the relationship.

  <p> The <code>ManyToOne</code> annotation may be used within an
  embeddable class to specify a relationship from the embeddable
  class to an entity class. If the relationship is bidirectional, the
  non-owning <code>OneToMany</code> entity side must use the <code>mappedBy</code>
  element of the <code>OneToMany</code> annotation to specify the
  relationship field or property of the embeddable field or property
  on the owning side of the relationship. The dot (".") notation
  syntax must be used in the <code>mappedBy</code> element to indicate the
  relationship attribute within the embedded attribute.  The value of
  each identifier used with the dot notation is the name of the
  respective embedded field or property.
  <pre>

      Example 1:

      &#064;ManyToOne(optional=false)
      &#064;JoinColumn(name="CUST_ID", nullable=false, updatable=false)
