The real power of location services will only be realized by integrating enterprise information systems with the mobile network to deliver mission critical information filtered through space and time. To achieve this goal, enterprises require highly flexible and modular component frameworks that can easily accommodate new value-add IP services, like location services. J2EE is designed to meet the needs of enterprises that want to serve their customers, suppliers, and employees with solid, complete, and scalable Internet business server solutions.

If you are a computer electronics manufacturer, service provider or content provider of location services, and you are trying to support diverse mobile devices, look no further. J2ME is designed for the combined needs of consumer and embedded device manufacturers who build a diversity of information devices; service providers who wish to deliver content to their customers on those devices; and content creators who want to make compelling content for small and resource-constrained devices.

MapObjects--Java Edition is a developer toolkit consisting of more than 900 Java developer components that you can use to build custom, cross-platform GIS applications, servlets or applets. It provides a robust, Java-based API that lets you design applications to perform a wide variety of geographic-based display, query, and data retrieval activities. MapObjects--Java Edition also includes prebuilt Java Beans that are easily used in the integrated development environment of your choice, such as Sun ONE or Borland's JBuilder software.

BBN Technologies' OpenMap package is an Open Source JavaBeans based programmer's toolkit. Using OpenMap, you can quickly build applications and applets that access data from legacy databases and applications. OpenMap provides the means to allow users to see and manipulate geospatial information.

The JAIN APIs for Integrated Networks bring service portability, convergence, and secure network access to telephony and data networks. By providing a new level of abstraction and associated JavaTM interfaces for service creation across Public Switched Telephone Network (PSTN), packet (e.g. Internet Protocol (IP) or Asynchronous Transfer Mode (ATM)) and wireless networks, JAIN technology enables the integration of Internet and Intelligent Network (IN) protocols. This is referred to as Integrated Networks.
