Haven’t seen much press on the JDesktop Network Component.
From the website: “Sun has launched the JDesktop Network Component (JDNC) open-source project on javadesktop.org. The primary goal of the JDNC project is to make it significantly easier to construct rich, data-centric desktop clients by providing shortcuts for many of the required design and coding tasks. This project currently contains a suite of high-level “data-aware” UI components, Java language API, and a high-level XML markup language that enables developers to get clients off the ground more quickly. Sun seeks to involve developers in the evolution of JDNC at this very early stage to ensure it that it fulfills its goal of simplifying enterprise desktop client development.”
