Here are the slides from my SpringOne sessions as PDF files: Spring and Eclipse RCP, Hands-On Spring-OSGi. The example that I showed during the Eclipse-RCP talk containing the example RCP application frond-end based on Spring-OSGi that communicates with the Spring-OSGi-based backend service running inside a Jetty server is also available for download. Here are the two example projects. You can use them together with the pre-defined workspace that I used during the hands-on session.
