+<h1>Generating dynamic entities from tables</h1>
+<p>When using EclipseLink JPA, you can create dynamic entities from your database tables. This dynamic persistence provides access to a relational database with all the benefits of JPA <span class="italic">without coding</span> or maintaining Java classes.</p>
+<p>Dali dynamically creates the classes at runtime, as needed.</p>
+<p>To generate dynamic entities:</p>
+<ol>
<li>
-<p><a href="tasks024.htm#CIHFEDEI">Error messages</a></p>
+<p>Right-click the JPA project in the <span class="gui-object-title">Project Explorer</span> and select <span class="gui-object-action">JPA Tools &gt; Generate Dynamic Entities from Tables</span>.</p>
+<img src="img/generate_dynamic_entities.png" alt="JPA Tools &gt; Generate Dynamic Entities from Tables" title="JPA Tools &gt; Generate Dynamic Entities from Tables" /><br />
+<p>The Select Tables page of the <a href="reference002.htm#CACGDFDJ">Generate Dynamic Entities from Tables wizard</a> appears.</p>

+<!-- class="figure" --></li>
+<li>
+<p>On the <a href="reference004.htm#CACBDJAC">Table Associations</a> page, specify which table associations should be generated. Use the <a href="ref_create_new_association_wizard.htm#CIAFGHIF">Create New Association wizard</a> to create additional relationships.</p>
+<p>Click <span class="bold">Next</span>. The <a href="reference005.htm#CACHHEEH">Customize Default Entity Generation</a> page appears.</p>
