Answered: Exception in a JPA application with multiple persistence units

Fri, 28 Jun 2013 08:09:07 +0000

If you have more than one JPA persistence unit defined in your persistence.xml file, you need to set

<exclude-unlisted-classes>false</exclude-unlisted-classes>

to:

<exclude-unlisted-classes>true</exclude-unlisted-classes>

and then list every entity class with a mapping definition for each.

Is this the case with your configuration?
