The client will be served gwt.js. This file will contain required GWT methods and
generally begins with the following JavaScript:
function DynamicResources() {
this.pendingElemsBySrc_ = {};
this.pendingScriptElems_ = new Array();
}
DynamicResources.prototype = {};
GWT is available at http://code.google.com/webtoolkit/.
Direct Web Remoting
Direct Web Remoting (DWR) is a true proxy AJAX framework. It works with existing
Java applications by functioning as a middleware servlet. Once installed, DWR is added
to the Java application??™s directory, and an XML file defining which methods should be
exposed is created by the developer. JavaScript methods are then compiled and point to
these functions. Finally, these JavaScript methods are sent to the client where they can be
called at any time.
Discovering DWR is generally quite easy. When a JavaScript file is served from the
/dwr/ directory of an application it will contain a list of methods in a human-readable
form. For example, if www.example.com uses DWR, a client will see JavaScript files
from www.example.com/dwr/ when first connecting to www.example.com.
DWR is available from http://getahead.ltd.uk/dwr.
