Version 2

    JBoss/JMS Message Reference


    The message reference is a pointer to the message. It holds one of:


    • A hard reference to the message in memory.

    • A soft reference with a pointer to the message in an offline store.


    To avoid continuous access of the message in the offline store it holds information used in the server, including:


    • A link to the queue/topic subscription

    • The message id

    • The priority

    • Whether the message is persistent

    • Redelivery information


    This is an abstraction of the message, it can also adapt other message types not just jms messages.
