使用Java消息服务（JMS）的点对点通信

Question

I have a simple question that I can't find an answer to. I know that a publisher and a subscriber have no connection to each other but how about queues? For a point-point communication, does the message producer have to establish a connection to the message consumer?

Answer 1

does the message producer have to establish a connection to the message consumer?

No - the producer passes the message to the JMS server (which acts as a store and forward device). The JMS server will pass the message on to the consumer.
