序一

随着X86服务器的普及使用，以及基于Linux和Windows操作系统在服务器上的主流使用，分布式计算，包括网络计算，和云计算，已经成为企业应用软件的主流模式。分布式应用软件的开发常常需要中间件的支持。基于消息的中间件（MOM）是使用最为广泛的中间件类型之一。如何正确和有效地使用这些中间件不仅影响到开发人员的编程效率，也在很大程度上决定了软件的结构和性能。

本书深入浅出的介绍了消息中间件的概念、原理和实现机制，并从软件开发人员的角度出发，详细描述了消息设计、消息传输中的数据类型的表示以及消息的发送、接受及其管理方式。本书对于从事分布式应用软件设计和开发的人员具有很好的入门指导作用和编程参考作用。

With the increasing aboption of x86 servers,and the mainstream use of Linux and Windows Operating Systems on servers,distrbuted computing, including,including grid computing and cloud computing,has become the key model for enterprise applicatons.The development of distributed applications often relies on the applicating middleware.message Oriented Middleware(MOM), such as MQ,JMS,TIBCO,are one of the most widely used type of application middleware.The peoper and effective use of such middleware not only affects developer productivite,but also largely determines the software architecture and performance This book guides the reader through the concept,prnciples and working mechanisms ofmessage middleware with an easyy to follow flow,lt details the design and data type representations of messaging,as well as send/receive and management mechanisms of messages from a developer,s pespective.This book serves as a good introductory guide and programming refereence for those who are involved in the design and developmeent of disributed applications
