Research Of Wireless WebService Based On Mobile Agents

In the past few years,the popularity of mobile phones and booming wireless communication technologies have largely enhanced the application users' request for the space,and promoted the enterprises' development in mobile application.Mobile platform starts to get more and more attention from both enterprises and individuals, and becomes the new focus in present applications.In the fields of new mobile application developing,J2ME as the one of the three Java language platforms has led the new technologies for many years,and almost has become the standard of the mobile application develop.Especially in the days when mobile phones and wireless communication technologies developed so fast,assessing Internet services through mobile phones has become a new trend,which is just led by J2ME platform technologies.On the other hand,Web service has gradually become the core technologies in the Internet field.It makes the integration of enterprise-level applications faster,easier and with better expansibility.Extending the services provided by Web to mobile equipments is absolutely the future direction of enterprise development.The thesis inquires into J2ME technologies,Web Service Technologies and the theory of mobile Agent technologies.On the base of the above knowledge,it studies a few present wireless WebService models which integrate J2ME platform and Web service.Through researching into the defects existing in these models,the thesis brings the mobile agent technologies into these models,and proposes the wireless WebService Model based on mobile Agent.After combining the query module of Yangtze River waterway management system,this thesis carries out the model in the project,gives the detail design and application of the entire system(It includes J2ME client,WebService Server,WebService Client,UDDI Server and Agent system design).As it practices,the prototype system developed on base of mobile Agent Wireless Web Service model runs in a good condition,which fully proves the correctness of the model design.It validates the model in the introduction of wireless Web Service Mobile Agent technology,and wireless Web Service model can improve and enhance the mobile client's ability to call Web services.
