The Study And Application Of JMS

Java Message Service is an open Application Programming Interface developed by Sun Microsystems Inc. It provides a common way for Java programs to create ,send , receive and read enterprise-messaging system's message. Differed from traditional messaging technologies, such as Remote Method Invocation, JMS promotes the reliability of asynchronous communication between components in distributed computing environments, and can be used for establishing loosely-coupled messaging system. Therefore, it simplifies the development of enterprise applications.Firstly, this paper analyses the current state of Java Message Service and illustrates the significance that using Java Message Service technology implements communications between enterprises. The paper forwards the designing method of JMS client application. Based on practical application requirements, this paper gives the sub messaging system total design and realizing the sub messaging system in point-to-point mode and publish/subscribe mode. Also in the paper, the message selector which supports filtrating the received message is given ,as the receiver how to filtrate a message from senders is one of the main problems in the sub messaging system development.Finally, the paper compares the capability of J2EE JMS and Weblogic JMS,which provides the correct method to select JMS provider.Now, this sub messaging system has been applied to the company and all performances are famous.
