The quote:
While I host this site on .NET primarily because SOAP based
services are so easy to implement in .NET, it's clear that the open
source and Java communities have considerably richer support for
REST today. The most advanced framework for REST that I've been able
to find is Jerome Louvel's deep and powerful Java-based Restlet
framework, available under the CDDL license. It provides full
support for REST-based resources, representations, connectors,
filters, and routers and also offers excellent examples of REST
architectures in the well-written and detailed tutorial.
