-<h1>Mapped superclass</h1>
-<p><a id="sthref72" name="sthref72"></a><a id="sthref73" name="sthref73"></a>An entity that extends a <span class="bold">Mapped Superclass</span> class inherits the persistent state and mapping information from a superclass. You should use a mapped superclass to define mapping information that is common to multiple entity classes.</p>
-<p>A mapped superclass <span class="italic">can be</span>:</p>
-<ul>
-<li>
-<p>Abstract or concrete classes</p>
-</li>
-</ul>
-<p>A mapped superclass <span class="italic">cannot be</span>:</p>
-<ul>
-<li>
-<p>Be queried or passed as an argument to Entity-Manager or Query operations</p>
-</li>
-<li>
-<p>Be the target of a persistent relationship</p>
-</li>
-</ul>
-<p>A mapped superclass does not have a defined database table. Instead, its mapping information is derived from its superclass. To override the mapping information for a specific subclass, use the <code>@AttributeOverride</code> annotation for that specific class.</p>
-<p><a id="sthref74" name="sthref74"></a><a id="sthref75" name="sthref75"></a><a id="sthref76" name="sthref76"></a><a id="sthref77" name="sthref77"></a>A mapped superclass is identified by the <code>@MappedSuperclass</code> annotation.</p>
-<p>Use this procedure to add Mapped Superclass persistence to an existing entity:</p>
-<ol start="1">
-<li>
-<p>Open the Java class in the <span class="gui-object-title">Package Explorer</span>.</p>
-</li>
-<li>
-<p>Select the class in the JPA Structure view.</p>
-</li>
-<li>
-<p>In the JPA Details view, click the mapping type hyperlink to open the Mapping Type Selection dialog.</p>
-</li>
-<li>
-<p>Select <span class="bold">Mapped Superclass</span> and then <span class="bold">OK</span>.</p>
