Patrick Linskey closed OPENJPA-228.
-----------------------------------
Resolution: Fixed
Persistent classes were not enhanced prior to use. Added a better error message in r532273.

[jira] Updated: (OPENJPA-228) Could not locate metadata for the
class using alias
Posted by "Tom (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/OPENJPA-228?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Tom updated OPENJPA-228:
------------------------
Attachment: bm.zip
This is the BM archive with "@Entity extends @Entity" instead of "@Entity extends @MappedSuperclass".
It does not contain the OpenJPA 0.9.7 jars in order to get a smaller file.

[jira] Commented: (OPENJPA-228) Could not locate metadata for the
class using alias
Posted by "Patrick Linskey (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/OPENJPA-228?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12491537 ]
Patrick Linskey commented on OPENJPA-228:
-----------------------------------------
I haven't run it yet, but a couple of things look suspicious:
1. You've got multiple @Entity classes called Article. The spec says that if an entity name is not specified, the name defaults to the short name of the entity.
2. Given that you're listing your persistent types, you should also list the generated classes as well. I think that this shouldn't be causing this problem, but it feels like it's best practice to list all or none of the classes.
