Design And Implementation Of The Cross-platform Cell Phone Mobile Middleware

This report design a cross-platform cell phone mobile middleware, which is based on thescript analytical engine and build dynamically with the client. It is in order to realize the mobileoperating system which have already existing in PC platform, and we give a further suggesion touse the html5technology to realize the data transmission, it can make the middleware moreexpressive and can support more cross-platform.The system operating environment is based onmiddleware module and the components of various mobile operating system platform for mobileclient,it including two parts:(1)Middleware module, it is build with two parts: the java programand the corresponding xml script. When the program started, the server-side load pre-write xmlfiles, resolve the xml files, then to call the database-driven and crawler module to get variabledata, assembled them into Json string and sent to the mobile client;(2) Every mobile operatingsystem platform have its own mobile client components, the function is to receive the datapresentation block and call the parsing module to present the data and building UI, and to makesure the business systems can be operated on terminal platform.The mobile client users’ responsemodule can collect user operating instructions, and returns them to the server-side, server-sideresponse to user requests, call the corresponding xml file and resolve the xml file, assembled thedata and then sent it to the mobile client.The specific work of this report is as follows:(1) On the basis of access to domestic and foreign literatures, summarizes the concept andmeaning of the cross-platform mobile middleware. Examples of several major cross-platformsolution and outlined the concept of middleware.(2) Summarizes the design requirements of cross-platform mobile middleware, and specificanalysis several cross-platform mobile development frameworks which are be used extensive.(3) Developed a Xml script protocol specification, write the Xml script which arecorresponding to the business, and selected the script parser which is to meet the requirementsthe experiment, select Json format as the data transmission between middleware server-side andmobile terminal, analysis and compared the three ways middleware server-side interactive data with business systems.(4) Construction the framework of the cross-platform mobile phone middleware, and realizethe college’s system on the mobile terminal through the middleware. Descript of every module’simplementation and core code in the framework. Including server-side; xml parsing module; dataassembly module; crawler module and json string’s send and parse module. And completed theexperiment successful.
