The Research And Implementation Of Mobile-Bank Application System Based On J2ME

With the development of mobile compute and the requirement of information access increasingly, enterprise applications are used in mobile and wireless connection areas. These more functional and convenient applications are needed for enterprises to extend their commerce application to earn more profitable investment repayment.Be compared with these traditional enterprise application, deploy mobile enterprise applications are faced with more serious challenge, including diversification of mobile communication devices, lack of uniform markup language and coexistence of different competitive wireless communication protocol.Combine J2ME with J2EE to deploy mobile enterprise application can solve these problems. J2ME is a branch of JAVA 2 platform used for applications of consume and embedded resource-limited devices especially suitable for these complex and intellectual process-needed client development. And due to its expansibility and flexibility, J2EE has been the actual development standard for server of enterprise applications. Based on the advantage of J2ME and J2EE when deploy mobile enterprise application, this paper combine the two platformand give an end-to-end mobile enterprise application-mobilebank, and do some research and discussion on the security when develop mobile bank applications.In this begin of the paper we introduce the development of mobile bank and analyze the research actuality of mobile bank in the whole world. Secondly we introduce these key technology when develop mobile enterprise application such as J2ME,J2EE,XML and data encryption in details. Then we introduce the system environment and run platform, the importance and difficulty when develop applications, bank server design and mobile client design. In the fourth chapter we give a blue print of the mobile bank developed by the author and give some picture of the blue print. After the discussion of mobile enterprise application development and the implement of a prototype of mobile bank we discuss detailedly on the network communicate security, the security of data exchange format in mobile bank applications, XML digital signature, MIDIet suite digital signature and how to confuse the source code of J2ME applications.
