Enunciate 1.4: Your JAX-WS endpoint published as a GWT-RPC endpoint

When you use Enunciate 1.4 to publish your Web service API, Enunciate will build you a war that you can drop into your favorite webapp container. The war will supply any or all of the following, depending on your configuration:

• Full documentation (scraped from the JavaDocs)
• Your service beans mounted via SOAP, along with the formal contract (WSDL, schemas, etc.)
• Those same service beans mounted via REST/XML.
• Those same service beans mounted via JSON.
• Those same service beans mounted as GWT-RPC endpoints.
• Client-side libraries for download (used for invoking your API programatically via SOAP).
• Client-side GWT Java libraries that can be used with GWT to support an AJAX app.
• Etc.

If you want to know more, I suggest a quick walk through the getting started guide.
