J2ee Specification-based Data Exchange System

Data interchange is a main issue of EAI. EAI is to settle the problem of data interchange and data share of isomerous system. Data interchange is the base of EAI. EAI is a means and technology to integrate isomerous applications based on different platforms and established by different ways. The ultimate aim of EAI is to integrate different EIS into a single platform to realize data sharing, data interchange and application integration and the existing applications will not be much modified in this process.The Java 2 Enterprise Edition (J2EE) specification provides a distributed services-based architecture for implementing highly scalable, reliable, and available e-business applications ? JCA(Java Connector Architecture) is the important supplement to J2EE standard, and its primary aim is to realize the integration between different EIS and various application servers based on J2EE standard. JCA is now the main integration technology of SunMicrosystem.The aims of the system are to realize data interchange between isomerous system, to manage and monitor the process of data transmission, to realize seamless joint to authentication module and to provide specified data interchange interfaces to application system.First, the importance of EAI and the role of J2EE and JCA in EAI will be introduced. Then the J2EE architecture will be analyzed in MVC design pattern. And then JCA and its mechanism is illustrated. In the end, an example to connect EIS by JCA technology will be given and data interchange will be realized between server and server in this example.
