Re: [eclipselink-users] How to create EclipseLink Sessions, ORM.xml files in J2SE environment
Hi Tom
Thanks for the reply. I started using pure JPA solution and that worked where I registered the entity class using persistence.xml file
 
Then I started looking at getting the same done using EclipseLink API and have developed this sessions.xml file attached below. I did not understand how I can register my TestETL class in the sessions.xml file. I am not using workbench at all. Do I need to configure both my sessions.xml file and and from either your project class or your deployment
xml(generated with the EclipseLink Mapping Workbench)
 
or
 
is it my sessions.xml file or project class or deployment xml ?
 
Appreciate your help.
 
Thanks
Kris

Hi Kris,

  This error generally occurs because for some reason the metadata for your
TestEtl class is not available to EclipseLink and you are treating it as
persistent.

  Depending on how you are configured, the metadata can come from different
places.

  If you are using a pure JPA solution, it will be derived from Annotations,
orm.xml and your persistence.xml file.

  If you are using the EclipseLink-proprietary APIs, it will be derived from
your sessions.xml and from either your project class or your deployment
xml(generated with the EclipseLink Mapping Workbench)

  Perhaps you can explain a little more about which of these files you are
using and what you are doing when you see the error.

-Tom

Verify that the descriptor has been properly registered with the Session.
