Direct Web Remoting (DWR) is a Java open source library for those wanting to develop Web sites which contain Ajax. DWR enables the Javascript in a browser to interact with Java on a server, just as if it were in the browser. DWR encompasses two main components; a Java Servlet running on the server that processes requests and sends responses back to the browser, and JavaScript running in the browser that sends requests and can dynamically update the Web page. DWR development is sponsored by TIBCO.
