On the following page, the referenced property example to add to ‘persistence.xml’ is not visible in FF, Chrome, nor Safari:
http://openjpa.apache.org/entity-enhancement.html See the section: OPENJPA-952 The last line of that section does not display the example property. (screenshot attached) Here’s the page source snippet: <blockquote> <p>[java] 1047 jpa_app WARN [main] openjpa.Enhance - Unenhanced classes were detected even though the enhancer has ran. Ensure that the EntityManagerFactory is created prior to creating any Entities.</p> </blockquote> <p>If your application uses some other method of enhancement, this support can be explicitly disabled by setting the following property in your persistence.xml.</p> <blockquote> <p><property name="openjpa.DynamicEnhancementAgent" value="false"/></p> </blockquote> <p><a name="EntityEnhancement-SubclassingEnhancement"></a></p>
