The Research And Implement Of EJB In Flight Operation System On C/S Framework

FOS(FIGHT OPERATION SYSTEM) is a operation system which can make the fights run more efficient by distributing the fight source real time. It is not only very important to the efficiently and safely run of ordinary fights but also very important to the air force. Nowadays, the research of fight operation has developed to efficient and multifunction. But how to get the balance of system work and make user get the result of operation as soon as possible is still an important problem during developing FOS.This paper bases on author's experience of developing an new fight operation system for a Japanese fight company on the platform of HP-UX/Oracle/WebLogic Server/Java during practice, this FOS can help worker decide the route of flight, supervise the state of plant, make out the flight plan and so on. Author makes researchs on lots of questioins during developing the system and reads lots of related documents, giving out the ways of how to deal with the questions. It will be useful to the development of same system. Firstly, this paper introduces the fight operation's characteristics, implement and latest development of fight operation in this world. Secondly, the paper introduces every technology in this program, analyses how to use smart client base on java in the system on C/S framework to improve the efficiency of system, reduce the press of server and ease the deployment, makes research of how to use EJB like in MVC framework in system of C/S framework to get the needs of operation from client to server and from server to server and so on, gives out the ways how to make the ideas become reality. At last, the paper introduces the content and process of function-test in large program, meanwhile giving the test-result of this program.This FOS has been used by the Japanese flight company, the system framework which consitituted by C/S, MVC and EJB plays well in the system by now, every model works well, the use of smart client has alleviated the load of service and enhanced the response rate of system.
