Donald Woods commented on GERONIMO-5553:
----------------------------------------

I decompiled your org.apache.sample.entities.Book.class and did not see that it had been enhanced.

In OpenJPA 2.0, we have turned RuntimeUnenhancedClasses off/unsupported by default (it was enabled in 1.0 and 1.2) -
    http://openjpa.apache.org/builds/2.0.0/apache-openjpa-2.0.0/docs/manual/manual.html#openjpa.RuntimeUnenhancedClasses

To enable runtime enhancement (which we strongly discourage for production applications), you need to update your persistence.xml to set the following property -
    <properties>
        <property name="openjpa.RuntimeUnenhancedClasses"  value="supported"/>
        . . .
    </properties>

The better solution, is to use build time enhancement, which can be done via ANT, Maven plugin or Eclipse plugin -
    http://openjpa.apache.org/entity-enhancement.html
