Starting the Subscriber and Publisher Clients
Start the subscribers, as described in
Starting the Subscriber Clients. Note that you cannot start
user1
as a subscriber because
user1
has permission to publish, but not to subscribe. As a result, you receive an exception message including the statement:
Operation not permitted.
User2
should start as a subscriber in the same manner as before.
You can now start
user1
as the publisher and send messages to
user2
, as described in
Starting the Publisher Client and Sending Messages.
