"JBAS011470: Persistence unitName was not specified and there are 2 persistence unit definitions ..." in EAP 6

Solution Verified - Updated -

Issue

  • Multiple persistence units are defined in a single persistence.xml included in an EAR
  • At deployment of the EAR, the following exception is raised:
JBAS011470: Persistence unitName was not specified and there are 2 persistence unit definitions in application deployment deployment "test.ear".  Either change the application deployment to have only one persistence unit definition or specify the unitName for each reference to a persistence unit.
