org.jboss.jms.message.JBossMessage
Implementation of a JMS Message Note that the only reason this class is Serializable is so that messages can be returned from JMX operations. Java serialization is not used to serialize messages between client and server in normal JMS operations @author Ovidiu Feodorov @author Tim FoxPartially ported from JBossMQ implementation originally written by: @author Norbert Lataille (Norbert.Lataille@m4x.org) @author Hiram Chirino (Cojonudo14@hotmail.com) @author David Maplesden (David.Maplesden@orion.co.nz) @author Adrian Brock$Id: JBossMessage.java 2284 2007-02-13 06:47:23Z ovidiu.feodorov@jboss.com $
