The Research Of Mobile Web Service Based On J2ME

With the fast development of wireless technologies and Internet, the mainoperation of mobile communication is changing from voice operation to dataoperation. Though, the traditional network technology brings users with theconvenience through the Internet, it lacks of mobility that cumbers its spread.Therefore, mobile office system becomes a new popular area of network technology.Meanwhile, in the market of e-business, it is impossible to command theparticipators using a model based on a single language and platform. Web service isthe next stage of evolution for e-business. It integrates the advantages of webtechnology and means of component faced. Using standard net agreement and dataformat of XML to transport. It is very ordinary and adaptable. In the large virtualenvironment of computer, any system that supports these standards can bedynamically located and communicates with other web services. Any users can makeuse of any services no matter where they are. So it make a breakthrough of the limit oftraditional computer model in the communication and using scopes, it permitenterprises and personals to put up the globe using fast and cheaply. Web service has evolved to its maturity period. With the potential market inmobile e-business growing rapidly, the demand for access to digital information usingweb services from mobile devices emerges.Fortunately, JCP (Java Community Process) has released WSA (JSR172) justrecently. The goal of WSA is to integrate fundamental support for web servicesinvocation and XML parsing into the device's runtime environment, so developersdon't have to embed such functionality in each application.The Stock price system mobile auction system, a typical case of mobilee-business, is built with web services in a standard way. It applies the newly releasedWSA API to achieve accessing web services on mobile devices, and achieve theintegrating of e-business and mobile web service. We believe that it must can drivethe development of e-business, and be good to driving the mobile e-business to be themail primary form of the future e-business.
