The Research And Implementation On The Technology Of End-to-End Wireless Enterprise Java

Along with the development of mobile computation and increase of the demand on information access, commerce is gradually developed in the domain of mobile and wireless connection. More powerful solutions of mobile and wireless connection are demanded by enterprise to extend their commercial applications, by which they can get more returns on investment.Compared with the traditional enterprise application, how to realize mobile enterprise application faces more challenges, including variety of mobile devices, absence of uniform markup language and coexistence of competitive wireless communication protocols.These problems can be resolved by deploying mobile application based on J2ME and J2EE. J2ME is a branch of Java 2. It is a platform for developing applications for mobiles devices and it is the best choice for the development of complex and intelligent client. J2ME application can be run on any MIDP-compliant device because it is independent of platform. Mobile devices can download application and run them offline on J2ME platform and access to Internet by Client/Serve mode. J2ME can work on all the network technologies and standards. J2EE is enterprise application development standards for its flexibility and extensibility. Based on the advantage of deploying mobile enterprise applications by J2ME and J2EE, the paper puts forward the solution of the technology of end-to-end wireless enterprise Java.XML is a kind of self-descriptive tag language, which is used widely in the area of web development for its special format and extensibility. With the analysis of the disadvantages of the data format adopted in most of solutions, this paper puts forward a method of transferring data between the J2ME client and the server based on XML formats in the wireless enterprise Java technology. The method not only can realize a large amount of data transmission, but also resolve the problem that data only can be transferred in a special format which the client and server appointed before the transmission. In the solution which put forward in this paper, how to parse XML document at the client by using kXML, how to track wireless sessions between the client and server by using XML document, how to ensure the security of mobile network by digital signature and encrypting data transferred between the client and server with Bouncy Castle API, how to envelope XML document are discussed.Finally, the paper applies the solution of wireless enterprise Java technology to the mobile airline reservation system and realizes the end-to-end communication. The data transferred between J2ME client and J2EE server are encrypted with Bouncy Castle and enveloped with XML format. By these ways, can client communicate with server more flexibly and safely.
