This example uses the same SendServlet code as in the first example, but the message consumer is now an MDB inside the same enterprise application (bundled in the same EAR).
这个示例使用与第一个示例完全相同的 SendServlet代码，但是，消息消费者现在是同一企业应用程序内的 MDB（绑定在同一 EAR 中）。
In P2P mode, a message producer sends a message to a specific message consumer through a queue, whereas pub-sub is intended for the one-to-many or many-to-many broadcast of messages.
在P 2 P模式中，消息的生产者通过队列传送消息给特定的消息消费者，而发布—订阅模式则以一对多或多对多的方式进行消息的传播。
By default, clustering load balances messages equally between the instances of CLUSQ1 on QM2 and QM3, even though CLUSQ1 on QM3 is not being served by a message consumer application.
默认情况下，集群机制在QM2和QM 3上的CLUSQ1的各个实例之间均等地平衡消息负载，即使一个消息使用方应用程序当时不对QM 3上的CLUSQ1提供服务。
In this situation, whilst the application server is offline, it is better to send all messages to CLUSQ1 on QM2, which has an active application server and message consumer application.
在这种情况下，当该应用程序服务器离线时，最好将所有消息发送到拥有一个活动应用程序服务器和消息使用方应用程序的QM 2上的CLUSQ1中。
Every consumer receives a copy of every message automatically without having to request or poll the topic for new messages.
每个消费者将自动接收每条消息的副本，无需请求或对主题进行轮询以获得新消息。
The same message can also be received by its consumer over any of those protocols, regardless of how it arrived in the bus.
在任意的协议上消息的消费者也能够接收相同的消息，与其怎样到达总线无关。
The retrieved message will not be available to any other consumer of the queue.
确保在指定的时间段内队列的其他消费者看不到已被接收的消息。
If you put a message in the input box and click Send message, the message appears in the command-line consumer.
如果你输入框中输入消息，然后点击发送消息按钮，该消息会出现在消费者端的命令行上。
Unless explicitly designed into the message content schema or topic space, a consumer has no knowledge of where a message originated.
消费者不会知道消息是从何处产生的，除非明确地将该消息设计到消息内容计划或着主题空间中。
Assume, for example, that the consumer sends a message to the service provider.
例如，假设，消费者向服务提供程序发送一条消息。
After the expiration, the message once appears in the queue, giving another consumer the chance to retrieve the message and process it.
过期之后，消息再次出现在队列中，让其他消费者有机会获取和处理它。
The most common response is to send an error message back to the consumer indicating that a timeout occurred.
最常见的响应就是向消费者回发一条错误消息，指出发生了超时。
It creates a consumer listening for a message with the selector that correlates the response to the request, as discussed above.
它将创建一个使用者，以按照上面讨论的方式使用将响应和请求关联的选择器来侦听消息。
First, a service consumer sends a request message to a service provider.
首先，服务使用者向服务提供者发送一条请求消息。
In addition a JMS client that produces a message is called a producer, whilst one that receives a message is called a consumer.
另外，产生消息的JMS客户端被称为是生产者，而接收消息的JMS客户端被称为消费者。
