Forgetting for a moment the question of how I manage sessions with Hibernate, I would like to know how I can raise and send an exception to the client from the PersistenceFilter class ie outside the context of the request.

You have two choices:
  • Return anything but a 200 status code, to trigger a "request transport error" on the server-side (handled by the RequestTransport on the client-side; it's generally used for authentication, as in the Expenses and Mobile Web App samples for instance)
  • Send back a "general failure" message. Use the MessageFactory AutoBeanFactory to create the message and AutoBeanCodex to serialize it. The message should consist of a ResponseMessage with a non-null generalFailure ServerFailureMessage. The other properties can (should) be null. The ServerFailureMessage properties map directly to the ServerMessage properties passed to the onFailure of the various Receivers.
