Research Of Wireless Mobile Data Operation Developing System Based On J2EE

Nowadays, application software are mostly based on PC, with the quick development of mobile communication network and the remarkable enhancement of the mobile terminal's hardware performance, as the available supplement and extension for application software, the precondition of both software and hardware for developing applications on mobile terminal has been ready. The choosing of software architecture is one of the most important factors which affects the success of the software during software development . The distributed service architecture has become the mainstream architecture in current software development because of its agility and flexibility. As the most popular distributed service framework,both the .NET and J2EE provide developers detailed specifications in design, integration, performance, security and reliability. However, with its platform independency, transplantable, open architecture and security, J2EE are more popular and used widely. This thesis mainly analyses the difficulty in current wireless mobile data operation developing and gives the feasible solution for it. Firstly, the current actuality and specialty of wireless mobile data operation are introduced. Thesis expatiates on the figure and advantage of J2EE as modern enterprise system by comparing it with other software architectures and platforms,at the same time,it introduces some core techniques and design patterns in J2EE; Then ,thesis analyses the requirement of an actual project <> which needs support different(multi) wireless terminals (GPRS,CDMA1X,SM,WAP) and promote the idea of"install once ,run anywhere"; furthermore ,thesis puts forward a data protocol which could be used in mobile data software development for reference and a developing framework which integrates development on different wireless terminals. The actual application project is developed and applied based on this protocol and developing framework. Finally, thesis concludes the project development of wireless data operation, and discusses the way of this developing framework and data protocol as well as the prospect of wireless data operation in the future...
