SOA is a Service Oriented Architecture, SOA is a mode architecture, and SOA implements currently there are currently a variety of options: Web Services, CORBA and JINI. Therefore, WebServices! = SOA. Industrial companies such as IBM, Sun and BEA have been announced that the middleware has ended, and the SOA era is coming; and the MiddleWare, which represents the famous THSERVERSIDE.COM website represents the open source community, does not take advantage of: The idea that the middleware has become history is like It is said that the railway, road or waterway is the same, and the middleware is the future. What is the middleware? Why have there be an argument to the end of the middleware? J2EE (EJB) is a typical middleware that integrates important core functions of the business system, such as distributed computing power; transaction mechanism; security permissions mechanism. At the beginning, people asked why the middleware advocate gave people such a scenario: if you are an IT software engineer of a large manufacturing company, when you start building a corporate information system, it will involve the user's rights system. Key system design such as cache performance system, constructing these basic technologies by enterprises, this will lead to key transfer of enterprise IT department work, because these systems need strong technical strength, therefore, the system for developing these general nature will give Enterprises bring huge risks. Entrust these key basic functions with universal nature to professional company, and enterprise IT departments can, for example, BEA will position WebLogic in the corporate platform, integrating powerful middleware functions such as workflow. In the JDONSD framework for me, this is a software development framework that speeds up J2EE development, shortens the J2EE development cycle, which is very interesting to such framework products, but found some problems in the actual communication process: I hope I can try this software. Customer trial involves code security, as long as the code is copied to the other party's computer computer, there is a possibility of decryption, so this issue is currently no perfect solution. How to provide a JDONSD framework to provide to a customer service in a rental manner, customers do not need to copy the JDONSD framework code, as long as they connect the JDONSD framework server, this similar way to provide a virtual host will implement software companies and customers win-win, In this way, the J channel can implement a special feature service, which is the reason for the birth of SOA (Service Oriented Architecture).
