Adding AJAX to Java with DWR

DJ Walker-Morgan of ZDNet Builder UK, has written about "Adding AJAX to Java with DWR (Direct Web Remoting toolkit)" on 15 August 2006. To quote:-

Making web-based Java applications more interactive doesn't need to be difficult. The Direct Web Remoting toolkit takes much of the hassle out of AJAX

DWR stands for Direct Web Remoting. The fundamental idea behind DWR is to make Java classes which exist on the server visible to JavaScript code running in the browser. Rather than writing your own AJAX code, DWR creates, based on the required Java classes methods and fields, the JavaScript code needed to access those methods and fields.
