Uma aplicação usando serviço baseado em localização e J2ME para celulares

Abstract

This work aims at developing of the an application for cell phones by using Java Micro Edition (J2ME), Location Based Services (LBS), and the Global Positioning System (GPS). In order to achieve this objective one bibliographic research was conducted on the latest technologies employed in this type of application. Based on this bibliographic research it was possible to decide the best approach to the system as well as the tools to be used. The system allows cell phone users to mark a certain location area by using an in-built GPS cell phone and send this information to a remote server that maintains this data in a Data Base. The development of this application demanded a study of the J2ME, LBS, GPS, Servlets, MySQL and the possibility of a HTTP connection through a cell phone. An analysis of these tools and their inter-relationship was also necessary so that the application could be planned and designed as a product with great possibilities within the mobile computing area. It is well known that studies in this field area are increasingly becoming more comprehensive and that the technologies investigated in this study represent a trend in the mobile computing market.
