-<h1>Mapped superclass</h1>
-<p><a id="sthref90" name="sthref90"></a><a id="sthref91" name="sthref91"></a>An entities that extend a <span class="bold">Mapped Superclass</span> class inherit 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>
-<li type="disc">
-<p>Abstract or concrete classes</p>
-<p>A mapped superclass <span class="italic">cannot be</span>:</p>
-<li type="disc">
-<p>Be queried or passed as an argument to Entity-Manager or Query operations</p>
-<li type="disc">
-<p>Be the target of a persistent relationship</p>
-<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>Use this procedure to add Mapped Superclass persistence to an existing entity:</p>
-<ol type="1" start="1">
-<p>Open the Java class in the <span class="gui-object-title">Package Explorer</span>.</p>
-<p>Select the class in the JPA Structure view.</p>
-<p>In the <span class="gui-object-title">JPA Details</span> view, use the <span class="gui-object-action">Map As</span> drop-list to select <span class="gui-object-action">Mapped Superclass</span>.</p>
