59. What are the three components of a Message ?
A1:
A jms message has three components
1. A header
2. Properties (Optional)
3. A body (Optional)
A2:
A JMS message consists of three parts:
Message header - For message identification. For example, the
header is used to determine if a given message is
appropriate for a "subscriber"
Properties - For application-specific, provider-specific, and
optional header fields
Body - Holds the content of the message. Several formats
are supported, including TextMessage, which wrap a
simple String, that wrap arbitrary Java objects (which
must be serializable). Other formats are supported as
well.
