This article provides a specific example, with code, of using Jersey and JAXB to implement a REST service suitable for consumption by an iPhone application.  It follows an earlier article (http://blogs.captechventures.com/blog/jack-cox/components-enterprise-iphone-restful-applications) in which I surveyed the components that can be used to create an iPhone application that consumes a REST service.

Components

Jersey

Jersey is an open source reference implementation of the JSR-311 (JAX-RS) specification provided by Sun.  In my client work with Jersey, it has proven to be a reliable and lightweight framework for providing REST endpoints and it integrates well with Spring, which will be shown later. 

Jersey is available from Sun at https://jersey.dev.java.net

Most substantial iPhone applications require some integration with information stored on a server and almost all enterprise iPhone applications require server integration.  This brief article describes some of the potential solutions for this integration problem and focuses on cataloging tools to solve the problem using a RESTful approach.  Future articles will describe the components in depths; including code samples.
