摘要：Geospatial applications will be woven into the fabric of the information society. Location based services (LBS) as a promising research field brings new opportunities and challenges to geographic information accessing, sharing and disseminating. The convergence of a number of technologies includes GIS, Internet, GPS, database, wireless communication and mobile computing. Through pull and push mode, the terminal users can access to required information – largely centre around their locations and surroundings . However, because of big variety of mobile devices, software of LBS has not typically been widely available for them. JAVA development environments provide a suitable method to gather requested information in an appropriate way. In this paper, some preliminary researches of LBS are introduced. A new architecture of LBS based on JAVA with Web Service is proposed and tested. These applications of LBS based on JAVA may be written once, and then deployed on any server platform that supports the Enterprise JavaBeans specification
