[jira] Commented: (OPENJPA-1808) Can NOT find meta class & can NOT
insert record in the table
[ https://issues.apache.org/jira/browse/OPENJPA-1808?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12913066#action_12913066 ]
Michael Dick commented on OPENJPA-1808:
---------------------------------------
Hi,
I think you need to generate the metamodel classes for your entities [1] (specifically the Course entity), I don't see them included in the zip file you attached.
[1] http://openjpa.apache.org/builds/latest/docs/manual/manual.html#d0e11094
The zip file was a bit confusing too, it's compressed using 7zip's algorithm - could you rename the extension to .7z to indicate that?

> 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!
> PS: I attached the code in the attachment.
