Answer / sachin
JMS Topic is a JMS managed object used to manage message
comminucation between publisher ( sender of message) and
subscriber ( receiver of message).
Queue is JMS managed object used for holding messages
waiting for subscribers to consume. When all subscribers
consumed the message , message will be removed from queue.
To put an anology with email system consider all emails
with subject 'Offers from Tesco Stores'. This subject is
called topic. If there are multiple messages of same
subject headings, it will be called as queue, waiting to be
read.

Answer / neeraj
Queue is point to point mechanism ( means once message is
picked up from queue no one else can pick up message )
while topic is pub sub mechanism ( means one Publisher and
different subscriber)

Answer / yogi_spysr
Topic>>> is a object which is used to get the producer on a
destination,, and we publish a msg and send it to that
destination,,,
so if we have many listeners to our msg then the msg will
be recieved by all recievers
:::: means it is a Kind of Publisher-Subscriber relation
one publisher and many subscriber
on the right hand we have
Queue >>>
is a object which link us to a queue
since in a queue of msgs and a msg will remain in queue
until it is recieved by the particular reciever who is
supposed to get it
its something like
MESSAGE --->> |Message Queue|--->> Destination
if msg is retrived then it is deleted
simply
when ::::Queue think of Mobile SMS service
topic think of Airtel SetUP Box
