Accessing Web Services

Abstract

In the last chapter, you learned how to establish connections to remote resources, such as remote web servers. While connecting to remote resources is a crucial component of many Java ME applications, most of today’s networked Java ME applications need something more: the ability to interoperate with today’s web services, the services provided by web servers designated for machine-to-machine interaction. Web services are an important evolution of the client/server model, and applications with clear user interfaces that present data, such as weather, financial, and travel information, from web services are in high demand as mobile users increasingly rely upon mobile devices for access to products and services.
