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.
