Research And Development Of The J2EE Enterprise-level Publishing Operation System Based On Open Source Software

Open source software is a new idea and pattern of software industry, it has a solid foundation after years of rise and fall. Widely used Web server Apache,Linux operating system and DNS server'SAND are both from Open source software.The article uses a J2EE application program, that is, an example of design and development for comprehensive publishing operation system for Sandong Overall Publishing Office,which displays the complete process of the project to provide a method of the application of open source software in different development phases and show how to apply the best open source software to develop J2EE application program. The text has the following four parts:The overall design is undertaken and systematic chart flow, technical frame and application frame are also given on the basis of analysis of comprehensive publishing operation system for Sandong Overall Publishing Office.Web level of publishing operation system applies Tomcat 5.0 as Web server in the development frame of Struts and in the MVC mode of overall frame.The development mode and open source software at different chart flows are selected according to research in open source software. The specific scheme is as follows:the application mode of XP, development frame in Struts, MySql for database system, Hibernate for Java data permanence tool and test tool and log tool in the choice of Jmeter and Log4j.The application of MySQL as database system and Hibernate as data permanence tool can develop permanence layer of publishing operation system. Its log function can be realized through the use of Apache currency log package and Log4j. And deploy publishing operation system to application server Tomcat.Respectively apply open source software Junit and Jmeter to the unit test and performance test of publishing operation system.The advantage of the application of open source software integration and development for publishing operation system is to save a high permission cost of software and provide a good expansibility and safety.
