<h1><a id="sthref27" name="sthref27"></a>The persistence.xml file</h1>
<p>The JPA specification requires the use of a <code>persistence.xml</code> file for deployment. This file defines the database and entity manager options, and may contain more than one persistence unit.</p>
<p>To enable you to easily edit this information, Dali provides the <a href="ref_persistence_xmll_editor.htm#CIACCHID">persistence.xml Editor</a>. Alternatively, you can use the Eclipse XML Editor to create and maintain this information. See <a href="task_manage_persistence.htm#CIHDAJID">"Managing the persistence.xml file"</a> for more information.</p>
