| <p><a id="sthref91" name="sthref91"></a><a id="sthref92" name="sthref92"></a><a id="sthref93" name="sthref93"></a>You can make a Java class into one of the following persistent types:</p> |
| <ul> |
| <li> |
| <p><a href="tasks004.htm#BABGBIEE">Entity</a></p> |
| </li> |
| <li> |
| <p><a href="tasks005.htm#BABFEICE">Embeddable</a></p> |
| </li> |
| <li> |
| <p><a href="tasks006.htm#BABDAGCI">Mapped superclass</a></p> |
| </li> |
| </ul> |
| <p>To add persistence to an existing Java class:</p> |
| <ol> |
| <li> |
| <p>Right-click the class in the <span class="gui-object-title">Project Explorer</span> and select <span class="gui-object-action">JPA Tools > Make Persistent</span>. The <a href="reference075.htm#CACIBDFB">Make Persistent dialog</a> appears.</p> |
| <div class="figure"><a id="sthref94" name="sthref94"></a> |
| <p class="titleinfigure">Make Persistence Dialog</p> |
| <img src="img/make_persistence_dialog.png" alt="" title="" /><br /></div> |
| <!-- class="figure" --></li> |
| <li> |
| <p>Complete the fields on the <a href="reference075.htm#CACIBDFB">Make Persistent dialog</a>, specify the persistence mapping for each class, and click <span class="bold">Finish</span>.</p> |
| </li> |
| </ol> |
| <p>Dali adds the necessary annotation or entry in the XML mapping file for the class.</p> |
