Subject: Qustion about "Broker"!
who could introduce "Broker" for me please? when should i need it?
JMS broker is basically a JMS server. It's a physical component that handles
the communication between clients. Instead of communicating with each other,
clients communicate only with the message broker. A client sends a message
to the message broker, providing the logical name of the receivers. The
message broker looks up client registered under the logical name and then
passes the message to them.
in the "ProducerAndConsumerTool" example, there is no "Broker"! is it
means
that "Broker" is not a requisite for commucation with jms ?
In the producer/consumer example, you must run the broker first (that is by
running activemq) before running the producer and consumer.
You can read more about JMS here: http://java.sun.com/products/jms/tutorial/
