Subject [jira] Commented: (GERONIMO-5553) Fail to enchance entities on Geronimo
Date Fri, 27 Aug 2010 18:53:54 GMT

    [ https://issues.apache.org/jira/browse/GERONIMO-5553?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12903529#action_12903529

Lin Sun commented on GERONIMO-5553:
-----------------------------------

Hi

After some initial investigate, it turned out to be a user error in persistence.xml.   The
class should be:

 <class>org.apache.sample.entities.Book</class>

while the one in the attached war has it configured as org.apache.geronimo.sample.entities.Book

This is causing the entity enhancement error as it was tried to enhance the wrong class.

After I made the above change, I am not seeing the entity didn't enhance error.  

P.S. This user case (a PU in war file) has to be a war file.  If it is a WAB, it won't work,
as the aries JPA doesn't support PU in WAB.

Please advise if this answer is satisfactory.  If so, you may close the bug.

Thanks

Lin
