Eai Specification Based On The J2ee Component Platform - The Run Agent Explanatory Platform

Many enterprises are now implementing electronic business based on Internet, so they want to realize the connection between electronic business and enterprise's inner application system. Because commercial data and service rules exist in different enterprise's application, for exactness it needs that electronic business program accesses enterprise's data and service rules, and copies these data to the program. So both enterprise's inner information and electronic business must be concerned with connection between systems, this is called Enterprise Application Integration. With the development of XML and application server, process sets between enterprises become EAI's mainstream. Process sets are procedures of creating commercial to integrate current application, and use a process engine to finish process' explanation and message routing. Such sets transfer discrete applications to commercial procedure system, which is flexible and suitable to B2B, but is difficult, either. This paper begins with new enterprise application platform, later it brings forward a feasible policy based on the procedure layer which is integrated to handle EAI. Through graphic IDE environment, it integrates current enterprise application, and uses XML service describing file, then stores them to service document. After that, it creates a new dynamic explaining agent (RUN AGENT platform). The platform calls XML service describe file in file library by client's request, then dynamic parses and executes, at the same time calls the modules. This plat form is based on J2EE. J2EE supports enterprise, multilayer and distributed web services, and provides widely support to enterprise module development too. It is suitable to develop module, reusable, and independent service logic.Dynamic explain RUN AGENT platform in technology is an advanced technology, and it is a quickly second enterprise application developing platform based on J2EE, which is called basic software frame platform in the field. By now, most platforms' production uses compile EAI, which creates enterprise application by IDE tool, and generates the code. Then they are compiled and distributed in J2EE. Such technology makes the enterprise application integration less difficult, but it is worse in performance compared with dynamic explaining RUN AGENT platform. The later one abstracts the service concerning enterprise application platform into an upper layer language (XML), which is more natural and lowers the system maintenance and develop period.The paper makes the introduction in three parts: ORMaping,RunAgent engine and IDE integrated tools.
