Message

Need implementations of JMS messages

• javax.jms.Message

• javax.jms.BytesMessage

• javax.jms.MapMessage

• javax.jms.ObjectMessage

• javax.jms.StreamMessage

• javax.jms.TextMessage

Also need implemention of the Message Selector.

NOTES

• The SpyMessage and selector implementations are a good starting point for implementation details.

• There should be a factory to allow alternate implementations to be used.

• Implement message header and message properties as separate objects.

• Need to include an optimization where the message body stays as a

  byte[]

  on the server, i.e. no unnecessary serialize/deserialize.

• Need to have an estimate of message size in memory for the caching implementation.

• Need to look at an optimized serialization rather than using Object serialization (for performance reasons).
