There and Back Again

AJAX library for php with a focus on doing all the coding php side. Allows for very clean html, as all the javascript is generated from your php classes. Basic development is object oriented and widget based. So on the javascript side you just attach your widgets to dom elements based on id. This leaves the heavy lifting to happen in php or in some other javascript library your pulling in. AjaxAC include code to auto generate various callbacks which is quite handy. The biggest problem I see is that if you don't create a javascript utility library you end up having to write lots of javascript inside php strings which is a mess to debug especially since it will spit out with other generated code making errors hard to track down.

AJAX library for Java generates JavaScript from Java classes. Proxy classes are used in JavaScript to call Servlet methods on the Java Tomcat server. Provides lots of examples to help you get started including a Multi-User chat example. Looks to support automatic fallback to iframes if XMLHttpRequest is not supported. Also has easy hooks for providing a global loading status.

Provides Cross Browser XMLHttpRequest based AJAX support, synchronous and asynchronous operation is supported. An object oriented api is offered to both JavaScript and PHP sides. Basic operation on the server side is provided by a server page where php objects you want to export are registered, this page is included in html pages with a client flag which generates proxy javascript classes with the same api as the php class (all class and method names are lowercase). Calls are made by creating an instance of the javascript class and then calling its methods. In async operation a callback class is specified when the instance is created, results are sent to methods with the same name as the called method. Provides complex datatype (multi-dimensional arrays and object) serialization and support for passing php errors to javascript, with configurable error handling on the javascript side.

Rico is a object oriented Javascript library that provides most of what you need to create AJAX applications. It supports ajax using either either content replace or callback objects. The drag and drop, effects, and behaviors so easy to use and look great in the demo. Rico is being developed by Sabre Airline Solutions and extends the Prototype js library using its effect and base classes.
