GSoC and Restlet integration with Equinox

Two years ago, we announced that NASA launched Restlet on the OSGi orbit by developing an integration of Restlet 1.1 with OSGi, based on Equinox extension points. This effort was presented at EclipseCon 2008 & 2009, and the code was contributed to the Ensemble project under a special license as explained by Bryan Hunt in this post. Also, listening to feed-back on OSGi from Restlet community, version 2.0 of the Restlet Framework was enhanced to ensure that all its modules and dependencies were available as good OSGi bundles.

However, even though deploying Restlet components and applications in an OSGi environment is already possible and explained in the user guide, it doesn’t take advantage of the dynamic and extensible nature of OSGi. Today, Bryan Hunt pointed me to a great tutorial written by Wolfgang Werner that nicely describes the Restlet Framework, covers its usage with Eclipse’s Plugin Development Environment (PDE) and explains how to leverage Equinox’s extension points to dynamically register Restlet components, applications and resources. See the series of posts titled “Building web services on Equinox and Restlet”:  part #1, part #2 and part #3.

But wait, there is more good news as a Google Summer of Code 2010 project “Restlet integration with Equinox” was proposed by the Eclipse Foundation and just accepted by Google! Thanks to Bryan Hunt for initiating the effort, to Equinox’s development team for supporting it, including Jeff McAffer, Simon Kaegi and Scott Lewis. We also received a positive review from Benjamin Cabé, an Eclipse contributor. Thanks also to all supporters including Jeff Norris and Khawaja S Shams from NASA, Rob Heittman from Solertium and Thierry Templier.

Two students proposals were submitted, one from Rajeev Sampath and another one from Samrat Dhillon. The first one was finally selected but Samrat has offered to contribute to the project. Rajeev is a Computer Science undergraduate student from University of Moratuwa, Sri Lanka, with good Java and distributed system experience as illustrated by his participation to the Epzilla project on Complex Event Processing (CEP).

I’m very happy to see this project, initiated by the Restlet community, taking shape and wish it full success. At Noelios Technologies, we will support it as co-mentor and encourage other interested parties to join and contribute. The project web site at Google Code is here… stay tuned!
