<h1>Adding persistence to a class</h1>
<p><a id="sthref91" name="sthref91"></a><a id="sthref92" name="sthref92"></a><a id="sthref93" name="sthref93"></a>You can make a Java class into one of the following persistent types:</p>
<ul>
<li>
<p><a href="tasks004.htm#BABGBIEE">Entity</a></p>
</li>
<li>
<p><a href="tasks005.htm#BABFEICE">Embeddable</a></p>
</li>
<li>
<p><a href="tasks006.htm#BABDAGCI">Mapped superclass</a></p>
</li>
</ul>
<p>To add persistence to an existing Java class:</p>
<ol>
<li>
<p>Right-click the class in the <span class="gui-object-title">Project Explorer</span> and select <span class="gui-object-action">JPA Tools &gt; Make Persistent</span>. The <a href="reference075.htm#CACIBDFB">Make Persistent dialog</a> appears.</p>
<div class="figure"><a id="sthref94" name="sthref94"></a>
<p class="titleinfigure">Make Persistence Dialog</p>
<img src="img/make_persistence_dialog.png" alt="" title="" /><br /></div>
<!-- class="figure" --></li>
<li>
<p>Complete the fields on the <a href="reference075.htm#CACIBDFB">Make Persistent dialog</a>, specify the persistence mapping for each class, and click <span class="bold">Finish</span>.</p>
</li>
</ol>
<p>Dali adds the necessary annotation or entry in the XML mapping file for the class.</p>
