Research And Application On Real-Time Monitor System Based On J2EE

With the development of Internet business and increasing network bandwidth, wide band has becomes the emphasis of constructing Information Expressway. Wide City Band (WCB) provides high-speed business platform for long-distance-monitoring. We design a Remote System with web technology, which is undoubtedly dominant in information platforms. Rapid development of computer technology and network technology provides definitely guarantee for building high quality enterprise system.On the other hand, the factories grow bigger and bigger, we provide information sharing inside the company to help making decision for the business, because traditional monitoring can not do the duty well any more. Through the integration of network technique and industry monitoring, we provide efficiently and reliable real-time-monitoring of the product process, it could help to deal with the accidents during product process on time. So it is the high time to build this kind of system for good.Here in this article, we present the items below:(1) In order to help understand the framework of J2EE, I introduce the N-tier application embedded in J2EE.(2) In order to help master the diagrams used below, I list the basic UML concepts here.(3) Design pattern, the mini-framework, the sub-framework, analysis and then design.(4) About Pushlet, we discussed the thesis and the virtues against other peer techniques, its implementation include two parts, one is the server side, the other is the client side. Based on pushlet, we provide real-time data exchange between server and many kinds of clients, such as browser.(5) We provide a sample application to publish the data inside the database to introduce the integration with former WEB application.(6) In the end, we give a conclusion of this article, and give further questions about it and further research directions.
