Using @OrderBy with a Shared Session Cache

Setting @OrderBy on a ManyToMany or OneToMany relationship field in which a List represents the Many side doesn't work if the session cache is shared. Use one of the following workarounds:

• Have the application maintain the order so the List is cached properly.

• Refresh the session cache using EntityManager.refresh() if you don't want to maintain the order during creation or modification of the List.

• Disable session cache sharing in persistence.xml as follows:

  <property name="toplink.cache.shared.default" value="false"/>
