The Design And Implementation Of Sandau WAP Based On Autogeneration Technology

WAP (Wireless Application Protocol) is a global and open wireless application protocol. It is brought up and developed under the need of accessing the internet on mobile. Nowadays the mobile equipment can access the internet via GPRS (General Packet Radio Service) and can browse the WAP site via WAP browser. The script for developing WAP site page is WML (Wireless Markup Language) or xHTML MP (Extensible HyperText Markup Language Mobile Profile), and the latter is conformed to WAP 2.0 standard and closer to HTML script. Lots of web sites, home and abroad, are now available via WAP. Scholars have done some research on how to transfer HTML into WML or xHTML according to WAP 2.0 standard.With the rapid development of mobile communication technology, going internet by the mobile equipment will be a trend. This research is mainly focus on how to extend the current website based on HTML and create its copy site based on WAP, which makes it possible for the user to achieve the same content from the WAP site by the WAP browser on his mobile equipment. This paper concludes some general WML or WAP 2.0 transcoding technologies: Build one new WAP site according to the current HTML site; Transcoding the current HTML into the WAP form immediately when the paged is visited; Use transcoding service from the third party.This research has done the analysis to the current solutions and brought up the autogeneration process of WAP site after the study of the composition of WAP page. The autogeneration process is:(1) Read the content information in form of HTML from the original site,(2) Transfer the HTML content information into XML,(3) ergod every one of the attributes of all XML nodes, delete the xHTML tags and attributes not supported by WAP,(4) check all nodes to find out whether there exists pictures or not, autogenerate the thumbnails and exchange the picture addresses, (5) autogenerate the result WAP page and make it a static WAP page.According to the construction goal of the digital Sanda University, after the requirement of University News Portal WAP site is understood and the current content management system on the back stage is analyzed, the extensive web service of the content management system is designed so as to integrate all the content data access interfaces of all the news portals in the university. In terms of the autogeneration process of WAP site, WAP page templates are designed first, the HTML contents are derived and transferred into XML, the results are analyzed, the thumbnails are created and pictures addresses are replaced, finally the combination of WAP template and WAP content are made into static WAP pages.The compatibility test of different pages of the autogenerated WAP site of Sanda University is on various WAP browsers under multi-platform and the test results are given.
