The specific code is as follows:
/*** @ Author administrator * @ description different from queue, topic implements the publish/subscribe model. In the following example, two consumers are started to listen to a topic together, then, multiple messages are repeatedly sent to the topic. * The result shows that each message is consumed by all consumers */package COM.

In the following example, two queue are created, and the sender sends a message to one queue. After receiving the message, the receiver replies a message to the other queue, then create a consumer to receive the reply message.
/*** @ Author administrator * @ Description: first, create two queue. The sender sends a message to one queue. After receiving the message, the receiver replies a message to the other queue, then create a consumer to accept the reply message */package COM. WL.
JMS as the senior part of the Java EE has been shrouded in a veil of mystery, as the JMS Customizer Sun only prescribes the JMS specification, as many other sun products have been provided by several vendors to implement the specific. But as Tomcat and resin (announced at the beginning of this year all support the Java EE specification). These low-end but widely

The JMS (JAVA message Service,java messaging) API is a standard or specification of a messaging service that allows application components to create, send, receive, and read messages based on the Java EE platform. It makes distributed communication less coupled, and messaging services more reliable and asynchronous.

1. Basic concepts of JMS 1. JMS (Java Message Service) is a standard API used to access the enterprise message system. It facilitates message systems.Java applications in the system exchange messages, and simplify the development of enterprise applications by providing standard interfaces for generating, sending, and receiving messages.

As it is, continue to improve the J2EE technical specifications. This time, we will write a JMS program. Understand the message-oriented middleware definition: Message

Introduction to JMS
JMS (Java Message Service ). It is used to transmit messages between applications.
Enterprise Message
WebSphere MQ, SonicMQ, Microsoft Message Queue (MSMQ), ActiveMQ, Message Bean in EJB, and ESB (Enterprise Message Bus) in SOA are all Enterprise messages.
Enterprise Message can be used in the following ways:
Centralized
Distributed
Hybrid

Today, most computing environments are made up of different platforms rather than sticking to any platform. The Java Messaging Service (JMS), together with Extensible Markup Language (XML), satisfies the desire for this heterogeneous environment integration. This article demonstrates how to use JMS to create xml-based messages and distribute them equally to Java and non-Java applications.

The cost of creating a connection from a WebSphere application Server to a Java message Service (JMS) provider, such as WebSphere MQ, is very high both in terms of time and processor requirements. To improve performance, WebSphere application Server maintains an idle connection pool that provides idle connections to applications when the application requests a connection to a JMS provider.
