Michael Dick commented on OPENJPA-1808:
---------------------------------------
I think you can add the -A option as a compiler argument to the
maven-compiler-plugin.
Or you can take a look at the openbooks example in SVN. It uses the antrun
plugin and an ant build file to generate the canonical metamodel classes.
Here are links to the pom.xml and build.xml we use in openbooks:
http://svn.apache.org/viewvc/openjpa/trunk/openjpa-examples/openbooks/pom.xml?revision=981587&view=markup
http://svn.apache.org/viewvc/openjpa/trunk/openjpa-examples/openbooks/build.xml?revision=980894&view=markup
Hope they help you get started.

> Hi,
> I wrote a jpa 2.0 test case.
> In the entity class Course.java:
> @ElementCollection
> @CollectionTable(name="COURSE_COMMENTS")
> private List<Evaluation> evaluation;
> Here member "evaluation" contains comments of the course in another
> Table:COURSE_COMMENT
> I run it on Geronimo 3.0 server(Geronimo server uses openjpa to provide
> its jpa service), howver, inserting record into the Table "COURSE" is NOT
> sucessful.
>
> The server gives warning such like this:
> WARN [DefaultThreadPool 198] openjpa.MetaData - Meta class
> "org.apache.geronimo.javaee6.jpa20.entities.Course_" for entity class
> org.apach
> e.geronimo.javaee6.jpa20.entities.Course can not be registered with
> following ex
> ception "java.security.PrivilegedActionException:
> java.lang.ClassNotFoundExcepti
> on: org.apache.geronimo.javaee6.jpa20.entities.Course_"
> Also can Not find meta class Evaluation_
> I'm not sure whether it is a problem created by OpenJPA?
> Could anyone help to have a look at it?
> Thanks in advance!
