Mechanisms Of The Java Message Service Applications

Over the years, with the rapid development of Internet, systems have grown significantly in terms of complexity and sophistication. More and more companies are faced with the problems of integrating heterogeneous systems, relieving system bottlenecks and other issues, the stability and reliability requirements of system components'communications are also increasing. Messaging offers the ability to process requests asynchronously, providing the solution for reducing or eliminating system bottlenecks, realizing decoupling between system components, ultimately increasing end user productivity and overall system scalability. Systems that utilize messaging provide architectural flexibility and agility.Through the research on Service-Oriented Architecture, Web Services and Java Message Service, this paper gives an asynchronous and reliable Web Service invocation model based on Java Messaging Service. The model ensures that messages are transmitted accurately, the sender need not block while waiting for receiver's answers, achieving a high degree of decoupling between both sides involved. With the background of Large Equipment Shared Management Platform of Chinese Academy, the article designs and implements the main functional parts of this model.By studying the Java Message Service publish/subscribe model, XML signature, encryption and other related technologies, the paper introduces identity authentication, access control, data encryption and decryption mechanism to supply the security gaps in Java Message Service Specification.
