Open Source AJAX Frameworks with Serverside Java Support
Posted by: ceperez Last Updated: 2005-11-04 06:28:49


It's time for yet another open source list. AJAX is all the craze these days. Although AJAX is primarily a Javascript based platform, I figure that developers would be interested in continually leveraging their Java skills. Therefore, this list is really about open source java support on the serverside for AJAX development. It's a mouthful but I hope you grok it. So here's the list:

* DWR - DWR (Direct Web Remoting) is a way of calling Java code on the server directly from Javascript in the browser. DWR consists of two main parts: JavaScript running in the user's browser to communicate with the server and dynamically update the webpage, and a Java Servlet running on the server that processes requests and sends responses back to the browser. DWR takes a novel approach to AJAX by dynamically generating JavaScript code based Java classes. Thus the web developer can use Java code from JavaScript as if it were local to the web-browser; whereas in reality the Java code runs in the web-server and has full access to web-server resources.
* JSON-RPC-Java - JSON-RPC-Java is a dynamic JSON-RPC implementation in Java. It allows you to transparently call server-side Java code from JavaScript with an included lightweight JSON-RPC JavaScript client. It is designed to run in a Servlet container such as Tomcat and can be used with JBoss and other J2EE Application servers to allow calling of plain Java or EJB methods from within a JavaScript DHTML web application.
* AjaxTags - The AJAX Tag Library is a set of JSP tags that simplify the use of Asynchronous JavaScript and XML (AJAX) technology in JavaServer Pages. This tag library fills that need by not forcing J2EE developers to write the necessary JavaScript to implement an AJAX-capable web form. The tag library provides support for live form updates for the following use cases: autocompl
