This topic describes how to work with fields in a message
header that identify and affect the behavior of messages.
About this task
In addition to the routing fields (see
Setting routing addresses in a message header), there are a number
of fields in the message header that you can work with. These fields
affect important qualities and characteristics of the message, like
priority and reliability, identity, and so on. See
Message header information for information
about the equivalence of the header fields to JMS message header fields,
and the methods available to work with them.
