Class PersistenceUnitAnnotationHelper

java.lang.Object
  org.apache.geronimo.j2ee.deployment.annotation.AnnotationHelper
      org.apache.geronimo.j2ee.deployment.annotation.PersistenceUnitAnnotationHelper

public final class PersistenceUnitAnnotationHelper
extends AnnotationHelper

Static helper class used to encapsulate all the functions related to the translation of @PersistenceUnit and @PersistenceUnits annotations to deployment descriptor tags. The PersistenceUnitAnnotationHelper class can be used as part of the deployment of a module into the Geronimo server. It performs the following major functions:

1. Translates annotations into corresponding deployment descriptor elements (so that the actual deployment descriptor in the module can be updated or even created if necessary)

Note(s):

• The user is responsible for invoking change to metadata-complete
• This helper class will validate any changes it makes to the deployment descriptor. An exception will be thrown if it fails to parse

Remaining ToDo(s):

• None
