Research And Implementation On System Model Of Web Services-Based On Mobile Agent And J2ME

Simplicity,open standards,flexible-efficiency and scalability,make Web Services widely used in many enterprises,organizations and institutions.At the same time,with high flexibility and reliability,Java ME technology has special advantages in integrating mobile device and enterprise application.So Mobile Web Services which unifies Java ME and Web Services,can provide flexible and convenient services anytime anywhere,and really achieves "Service on demand".Therefore,the perfect combination of the two technologies will provide more powerful application supports in the period of increasing bandwidth and optimal transmission,and it is of great significance to the exploration of business model and the development of mobile e-commerce technology.However,current technology is not mature,there are many inadequacies.The purpose of this thesis was to propose some solutions for these shortcomings, then tried to improve the practicality and efficiency of the system,finally designed an ideal KMAgenice system model.With the mobility of the population gradually increased,the mobility of criminals was also gradually increasing,it was necessary to establish a mobile data system to limit vicious crimes and to improve response speed of the detection.In view of this,the paper would make the KMAgenice system model instantiated,and design a simple prototype of the mobile police system.The thesis started with Java ME technology and Web Services technology.First, we simply introduced the architecture and key technologies of Java ME platform,the technology advantages,standards and protocols of Web Services,the working mechanism of Web Services model,the architecture and key technologies of Mobile Agent,as well as the advantages and disadvantages in the distributed application areas of Mobile Agent.Second,the paper is focused on the architecture of Mobile Web Services which unifies Java ME and Web Services,through deeply analysis we found the inadequacies of the current Web Services system model based on JSR172, and established an ideal system model—KMAgenice.After that,we designed a prototype of the mobile police system to display the design process,the development platform and deployment of the entire project.Then,we explored the securities of the system from three aspects—the securities of Java ME client,the main technical securities of Web Services security layer,the security of Mobile Agent,and provided simulative tests and performance tests to the whole system.Last,the paper gave a summary and prospect of the full text,proposed the direction and content of the further study,and prepared a comprehensive work for the next step.
