<h1><a id="sthref58" name="sthref58"></a>Managing the orm.xml file</h1>
<p>When creating a JPA project, (see <a href="task_create_new_project.htm#CIHHEJCJ">"Creating a new JPA project"</a>) you can also create the <code>orm.xml</code> file that defines the mapping metadata and defaults.</p>
<p><a id="sthref59" name="sthref59"></a>Eclipse creates the <code>META-INF\orm.xml</code> file in your project's directory:</p>
<pre xml:space="preserve" class="oac_no_warn">
&lt;?xml version="1.0" encoding="UTF-8"?&gt;
&lt;persistence version="<span class="italic">&lt;PERSISTENCE_VERSION&gt;</span>"
