Examples of MessageIdentity

org.activemq.service.MessageIdentity
Represents a message identity, either by using a unique message number, which is ordered and must not be zero or by specifying the String messageID.
Typically a client accessing the MessageStore may have one or the other. Depending on which one is specified the other value may be filled in by operations on the MessageStore @version $Revision: 1.1.1.1 $
