<h1>Synchronizing classes</h1>
<p>As you work with the classes in your Java project, you will need to update the <code>persistence.xml</code> file to reflect the changes. <a id="sthref43" name="sthref43"></a><a id="sthref44" name="sthref44"></a></p>
<p>Use this procedure to synchronize the <code>persistence.xml</code> file:</p>
<ol start="1">
<p>Right-click the <code>persistence.xml</code> file in the <span class="gui-object-title">Package Explorer</span> and select <span class="gui-object-action">JPA Tools &gt; Synchronize Classes</span>.</p>
<div align="center">
<div class="inftblnote"><br />
<table class="Note oac_no_warn" summary="" cellpadding="3" cellspacing="0">
<td align="left">
<p class="notep1">Note:</p>
Use this function if you selected <span class="bold">Annotated classes must be listed in the persistence.xml option</span> in the <a href="ref_jpa_facet.htm#CACIFDIF">JPA Facet page</a>. In general, you do not have to use this function within the container.</td>

<p>Dali adds the necessary <code>&lt;class&gt;</code> elements to the <code>persistence.xml</code> file.</p>
<p>Use the <span class="gui-object-title">Persistence XML Editor</span> to continue editing the <code>persistence.xml</code> file.</p>
