“Restlet in Action” book progressing in MEAP March 3, 2011

When we launched our “Restlet in Action” book project via the Manning Early Access Program (MEAP), we knew we had a long road ahead. This effort has been a source of intense work, an opportunity to step back, take the user seat and exchange in new ways with our community. For example, we have already been through two external reviews and had very regular discussions with readers in the book forum.

The book is now expected to go for printing during Summer 2011, synchronized with the release of Restlet Framework 2.1.0 version. Note that the book will cover both 2.0 and 2.1 versions of Restlet.

Recently, we have published the first two parts of the book, including the first 8 chapters in a total of 12. As it stands, the book already provides very valuable information for both Restlet newcomers and more experienced developers. In addition to presenting the technology we also provide guidance on how to design a RESTful web API, a very hot topic nowadays.


Our immediate priority is to write chapter 9 and finish the edition of chapter 10 in order to release them on MEAP in the coming weeks. Like chapter 7 on security which was contributed by Bruno Harbulot, those two new chapters covering Restlet usage with browsers, mobile devices and cloud platforms are being contributed by Thierry Templier, an experienced writer and engineer that will join our company, Noelios Technologies, next month (welcome to Thierry the Second!).

Over the past weeks, a second review of the manuscript was completed thanks to the help of about 10 external reviewers. We received very detailed feed-back, with many suggestions for improvements and corrections. As a result, we have established a thorough action plan containing about 50 action items that we intend to address. We have also addressed the easier comments on the fly by fixing the manuscript like we generally do with feed-back received via this book forum.

The next priority will be to work on this action plan and in parallel write the two other remaining chapters on  “Embracing the Semantic Web” and “Looking beyond this book”. Finally, Manning will launch the printing process, including precise copy edition to improve the English prose and the general writing flow (we are not native English writers!). Thanks for your interest and support, we are almost there!

Microsoft selects Restlet to show REST interoperability February 20, 2009

Posted by Jerome Louvel in Ecosystem, Microsoft, Noelios, REST, Restlet, Restlet General, User interface.

After a long investment in WS-*/SOAP initiatives, Microsoft has recognized the value of REST. But they didn’t adopt REST only on the surface, they have put in place a comprehensive offer and are actively working to demonstrate and facilitate the interoperability with other platforms such as Java.


Facing a strong competition in the Rich Internet Application area, from Google with GWT, from Adobe with Flex/AIR/Flash and more recently from Sun with JavaFX/Applets, Microsoft has finally reacted with the introduction of their Silverlight 2 technology.

Silverlight requires a browser plug-in (ActiveX available for IE, Firefox and Safari) and provides you with a subset of the .NET Framework. Microsoft supports Windows and Mac while Novell has a Linux version called Moonlight. For the user interface it relies on a declarative language called XAML, not too different from Flex MXML or JavaFX scripts.


Regarding communication, it relies on WCF and offers direct support for HTTP/REST, RSS and Atom, POX/JSON and XML/LINQ. A description of the full architecture is available here.

Now, if you follow this blog, you are probably wondering how Silverlight interoperates with Java on the server-side. Even if its support for HTTP has a few limitations (partially due to its nature of browser plugin), Silverlight allows you to communicate easily with a REST back-end.

To demonstrates this, Microsoft has leveraged our Restlet framework and illustrated this interoperability with several detailled posts in their Silverlight plus Java blog written by Stève Sfartz from Microsoft. Other examples are available on Blog in the Cloud and Cloud it up.


If you are a traditional Microsoft developer, you would naturally turn to Visual Studio to develop your Silverlight applications, but what if you are a Java developer?

Well, Microsoft has done an unusual move by supporting the development of a Silverlight IDE for Eclipse! It’s called eclipse4SL and is co-developped with Soyatec, a French software editor specialized in Eclipse products development.


REST interoperability is also covered in eclipse4SL’s user documentation, illustrated by the usage of Restlet on the server-side. See this page for Restlet guidance. This is currently based on Restlet 1.0 and a Tomcat deployment, but work is underway to upgrade to Restlet 1.1.

The eclipse4SL project has even been submitted to the Eclipse foundation. See this post from the executive director of the Eclipse foundation.


After meeting with Stève Sfartz, who very enthusiastically introduced us to Microsoft projects for REST, cloud computing and RIA, we worked on a join presentation for the Microsoft TechDays in Paris.

The goal was to present interoperability scenarios around REST. Thierry Boileau did the presentation for Noelios Technologies. A detailled summary (in French) has been posted by Stève Sfartz on his blog.


This presentation gave us the opportunity to show case our recent support for the Shared Key HTTP authentication scheme. This protocol is similar to the one defined for Amazon S3 and allows you to access to Microsoft Azure Data Services from a Restlet Java client.

This new feature is available in recent snapshots of our future Restlet 1.2 release!

Update 2: Stève Sfartz has posted a complete article on MSDN detailling the example showcased at the TechDays (in French), including downloadable source code.

Announcing Noelios Technologies August 4, 2008

Posted by Jerome Louvel in Noelios.

Created in 2004, Noelios Consulting was a self-owned company that served its customers world-wide and that funded most of the development of the Restlet project. Four years have passed, Restlet has grown into a widely used technology and it was time to move to the next level, to better structure our business activities, and in the end to better serve all our customers and users.

Noelios Technologies is happy to announce its incorporation, effectively taking over all the assets of Noelios Consulting. Thierry Boileau, who has been a core developer of Restlet for a long time, is officially joining me as a co-founder. Our activities are still focused on consulting services, but with an increasing part in software edition.

We are also launching our brand new Web site with a revamped products and services offering. We have added new support plans (Gold and Platinum) and shorter subscription lengths (from 1 month to 1 year). You can even directly subscribe to our support plans, get commercial Restlet licenses and even pay on-line via PayPal.

This is an important evolution for us and we look forward to helping you succeed with your REST and Restlet projects!

My name is Jérôme Louvel, I’m an independent software consultant and author of the Restlet framework which aims to bring the simplicity and efficiency of the REST architectural style to Java developers.

In this blog I’m planning to share some thoughts about Java, REST, XML and related technologies.
