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

As discussed in an earlier posting, creating a Domain Model is critical to a successful SOA implementation. But how do you effectively utilize this model within your code base as you start to develop applications that are in tools or languages that do not manipulate the XML directly?
