BytesMessage

Synopsis

A BytesMessage is a Message that contains an uninterpreted stream of bytes as its body. This would typically be used to wrap an existing (non-JMS) message format so that it could be delivered over JMS. Data is written to the message’s binary body using its write methods, and read using its read methods. Once a BytesMessage has been created (using a series of write calls), the reset() method can be used to put the message into read-only mode. Until this is done, the message is in write-only mode, and the contents cannot be read back.
