【摘要】 数据交换是EAI的核心问题,EAI要解决异构系统之间的数据交换和数据共享问题,数据交换是EAI的基础。EAI是将基于各种不同平台、用不同方案建立的异构应用集成起来的一种方法和技术。EAI的最终目的是要将企业的各种EIS集成到一起,这一过程应尽可能不对己有的应用程序做出(过多)的修改,并实现数据共享,数据交换和功能集成。 Java 2 Enterprise Edition(J2EE)规范提供了实现高度可伸缩、可靠和可用的电子商务应用的分布式基于服务的体系结构。JCA(J2EE连接器架构,Java Connector Architecture)是对J2EE标准的重要补充,其主要的目的是为了实现各种EIS与基于J2EE标准的应用服务器的集成,目前已经成为Sun公司主推的集成技术之一。 课题目标是:1)实现异构系统间安全数据交换。2)对数据传输过程进行管理,监控。3)与认证模块实现无缝衔接。4)为应用系统提供规范的数据交换接口。 论文首先介绍了EAI的重要性,以及J2EE、JCA在EAI中所扮演的角色;接着论文结合MVC设计模式分析了J2REE的体系结构;然后论文又介绍了JCA及其原理;最后论文给出一个采用JCA技术连接EIS的实例,在这个实例中将实现服务器和服务器之间的数据交换。更多还原

【Abstract】 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.更多还原
