Question :What is the difference between the Mailing and Messaging? (JMS)
Answer :Java Mailing is the set of APIs that primarily concerns with the sending of
Mail messages through the standard mail protocols. Messaging is the way
of communicating to the remote machines using Message Oriented
Middlewares. Message Oriented Middlewares do not use mailing internally
for communication. They create their own channels for communication.
