Since the launch of Restlet 1.0 in April 2007, we have been working hard to prepare this new version. To protect your investment in existing code, we have maintained the initial API design, extending it where necessary and always ensuring a direct if not transparent migration path.

Here is a selection of the most exciting new features:

  • Broader and deeper HTTP support with features such as partial downloads, resumable uploads or content integrity validation.
  • Best support for the WADL specification in the industry, allowing an automatic and always in sync documentation of your REST APIs. WADL documents can be generated in XML or converted on the fly to HTML using the popular stylesheet from Yahoo!
  • One of the first and most complete implementations of the new JAX-RS 1.0 specification provided for those preferring an annotation-oriented approach.
  • New Restlet-GWT module provided, porting the client-side of the Restlet API to the popular Google Web Toolkit 1.5 JavaScript platform, allowing you to invoke RESTful applications right from your Web browser.
  • New extensions for easier integration with the JAXB 2.1, JiBX 1.1, Spring 2.5, OAuth, OSGi, Oracle XDB and SSL technologies.
  • Improved support for Atom Syndication XML format and for Atom Publishing Protocol. Both formatting and parsing are now available.
  • New POP3 connector based on JavaMail to access RESTfully to remote mail boxes.
  • New Grizzly HTTP server connector, first to fully leverage the NIO support in the Restlet API, leading to new levels of scalability and performance.
  • New internal HTTP client and server connectors to simplify development phases (zero configuration necessary) and allow very small footprint deployments.

Direct contributors since 1.1 RC2:
  • Aaron Crow
  • Aaron Roberts
  • Adam Harris
  • Bruce Lee
  • Diego Ballve
  • Erik Beeson
  • Jérôme Bernard
  • Kevin Conaway
  • Richard Hiberman
  • Tim Peierls

In addition, we have significantly expanded our documentation with a 150 pages long Restlet User Guide, a screencast and first steps tutorials. We have also added new licensing options: LGPL 3.0 and transferable commercial licences (OEM).

You just need to download Restlet 1.1.0 to enjoy those new features !

  6. I have used the installation and hello applications.

    Eclipse says that “org.restlet.resource.ResourceException” is missingg

  7. Hi Denis,

    Are you sure you have installed Restlet 1.1? ResourceException didn’t exist in Restlet 1.0 which may explain your issue.

    Best regards,

  8. Is there a page anywhere detailing how to upgrade from 1.0 to 1.1? Its very well hidden if it exists, as I’ve searched through the site. If it does exist, then please edit the original post to add the link.

  9. Hi Stephen,

    There is a “Migration guide from Restlet 1.0 to 1.1” available in the User Guide. Here is the link:
