If you opt not to create an orm.xml
file when you create a JPA project, you can create one using the Mapping File Wizard.
Use this procedure to create an orm.xml
file:
From the Navigator or Project Explorer, select File > New > Other. The Select a Wizard dialog appears.
Select Mapping File and then click Next. The Mapping File page appears.
If you are using EclipseLink, you can select EclipseLink > EclipseLink Mapping File.
Define the properties in the page and click Finish. The orm.xml
file appears in the src directory of the selected JPA project. You can manage the orm.xml file using the JPA Details view or through the XML Editor. See also JPA Details view (for orm.xml).
