The Implementation Research On The Frame Of J2EE-Based Agent System

These days, software agent technologies are right at the threshold betweenResearch and wider industrial use. Surveys and conferences show that only fewsuccessful real-world applications using software agent technologies have beenimplemented on a larger scale –quite comparable to object-oriented technologies inthe late eighties and early nineties. In the real IT-world, also software agenttechnologies are not, and will not be, used for their sheer beauty. As experience shows,this trust is much easier built if there is a sound basis of known technologies andproven products, how can we build agent-based business systems and applicationsusing current state-of-the-art, proven technologies and products? This article describesan approach to build an agent system based on J2EE application servers in a quite newway. This paper concentrate on:The analysis of J2EE architectureThe Architecture put forward by this paper is based MVC frame of J2EE. EJB isresponsible for task-processing: accept the request of Web, and get the data fromback database which is needed for the processing and then return the result to theoriginal Web tier for display. Thus we separate the layers of the function.The construction of the Agent architecture based on J2EEAfter the analysis, we decided to replace the Agent component for the EJBcomponent. And give the environment to the Agent for living in J2EE server.Thus we get a mixed architecture based on J2EE and Agent.The message mechanism of the architectureAfter the deep analysis, we get the core of Jini technology. And we develop thecommunicate mechanism based on IP multi-cast technology.This paper present a new architecture letting agent residing in the middle tier ofthe J2EE server ,where they should pursue their tasks in coordinated ways.
