Check out this tutorial on the use of WADL to add a service to Zembly. For those not already familiar with Zembly it is:

"An application development environment that not only targets the web as its native platform, but uses cutting-edge web innovations such as web services, social networking, and Web 2.0, to change the way applications are built, deployed, scaled, and delivered to where users congregate."

Essentially any service described by WADL can be easily used within a Zembly application. If you are using Jersey to build your service then support for WADL comes free.
