In this week's java.net Spotlight, we're featuring Ed Ort's new three-part article series, Introducing the Java EE 6 Platform. Ed Ort is a Sun Developer Network staff writer; he's written extensively about database, programming, and web services technology. Part 1 of the series looks at the goals of the Java EE 6 platform. These include: More flexible technology stack Enhanced extensibility Further ease of development Among the leading new Java EE 6 technologies, Ed cites the Java API for RESTful Web Services (JAX-RS), JSR 311. JAX-RS: enables you to rapidly build lightweight web services that conform to the Representational State Transfer (REST) style of software architecture. An important concept in REST is the existence of resources, each of which can be referred to with a global identifier, that is, a URI.
