Java Enterprise in a Nutshell, Second Edition

Name

DeliveryMode

Synopsis

This interface defines constants that represent delivery modes that a JMS provider can support. NON_PERSISTENT delivery implies that a significant failure by the provider before a message can be delivered will cause the message to be lost. PERSISTENT delivery mode implies that the provider will store message to persistent storage, and that the messages will survive a crash by the provider. Message senders specify the delivery mode for a message in its header, using the Message.setJMSDeliveryMode() method, and the provider is responsible for honoring it.

   public static final int PERSISTENT;                           // =2
