JDA is a nimble, kevlar-booted javascript message-passing kernel which manages communication between separate javascript modules and enforces that modularization. JDA stands for Javascript Dataflow Architecture. It is an open standard developed by MAYA Design Inc.<BR><BR> <H3>Benefits of Modularization<BR></H3>One would think that the Object Oriented revolution would have resulted in a sufficient modularization of software in itself, but recent years has seen the rise of several different types of "external" techniques to further separate parts of code from other parts, mostly for the sake of reuse, but also to release the programmers of the burden of tracking inter-connectivity of different parts of a system.<BR><BR>In the Java world, we have Spring as a very good example. Spring has many features, but one of the most obvious is automated configuration and 'wiring' of loosely coupled objects. What does this mean? It means that you can write a java program as a couple of different objects that can use each other, and which can accept initialization data, but nothing explicit about initialization or connections to other objects is ever mentioned ... <a href='http://www.ajaxmatters.com/articles/gen/javascript_dataflow_architecture_p1.aspx' target='_blank'>[Read Full Article]</a> http://204.9.76.234/articles/gen/javascript_dataflow_architecture_p1.aspx Dealing with Long Running Processes in ASP.NET <P><STRONG class=textBoldBlue>Introduction</STRONG><BR><BR>. Whether we use Ajax or not, if it is a very long running process the browser may show a time-out error. <BR>In case of ASP.NET AJAX if we use a script manager then we also have to define the time-out for the request which can be difficult in the scenario where we cannot predict how long a process will take to execute.<BR>In this article we will discuss about this issue and how to use Ajax to handle long running process by using IAsyncResult and ICallbackEventHandler.</P> <P>Web applications are based on a client-server architecture, so when the client hits the server the server will reply. If a long process is running on the server, then we may need some mechanism to determine when the long process is over. The long process can also delay the execution of other processes. To handle this issue we will use IAsyncResult . Using this interface and delegates we will able to run asyncronous processes on server side and invoke one method on server side while continuing with other tasks; once first method is complete it will automatically call another server method so that we can update some parameters say VAR1 and VAR2.

When a Server is required to do some processing in a web-app Services must be used. A service is used to invoke server-side code from the client (and vice-versa occasionally). </P> <P>In GWT the Client side code pages run more like an application within the Client (Browser), so requesting the HTML pages from the Server is not necessary. But in common with all Server-Client Architectures, even GWT needs to contact the Server as they execute, this is carried out by Remote Procedure Calls (RPC). <BR> <BR><SPAN class=TextBoldBlue><STRONG>What is RPC?</STRONG> </SPAN><BR></P> <P>RPC is a powerful technique for constructing distributed, client-server based applications.

Any server side technology that supports JavaScript also supports AJAX. AJAX is a browser technology, and is therefore independent of web server platforms. </P> <P>In this article we will learn about what AJAX is, how it works, and how can we use AJAX with PHP. Please remember, AJAX is not a programming language, so you don’t have to learn any new technology. AJAX can be implemented by using existing standards (JavaScript and XML) in a different way. <BR><BR>If we are using PHP or any server side technology and need to extract data from storage on a server (eg a database or a file), we will have to make an HTTP request (either POST or GET) to get the data. Once the data is received the the web page will need to be reloaded to show the data. Using AJAX technology we can request and receive the data from server in background and then display it on the page without a reload. AJAX uses HTTP requests for this. With AJAX, JavaScript communicates directly with the server, through the JavaScript XMLHttpRequest object (XML over HTTP).

Unlike Postback, in Callback only user defined information is sent to the server. Instead of using Postback to post the page, ICallbackEventHandler uses the DoCallback event to send user defined data to server, and return a String to client; on the client-side JavaScript can then manipulate the string. In total we have to use four functions for the implementating ICallbackEventHandler; two client side functions (in javascript) and two server side functions (C# in this case).<BR><BR><STRONG class=textBoldBlue><BR>Use of ICallbackEventHandler:</STRONG><BR><BR>To use ICallbackEventHandler, we will need to inherit it on the page or in a user control. The code will for this will be:</P> <P class=textCode>public partial class Default2 : System.Web.UI.Page,System.Web.UI.ICallbackEventHandler<BR></P> <P class=textCode>As a result of inheriting from ICallbackEventHandler, we have to implement two functions, namely: </P> <UL> <LI class=textCode>public void RaiseCallbackEvent(String eventArgument) <LI class=textCode>public String GetCallbackResult()</LI></UL> <P>As name of the above two functions indicates, the first function gets called automatically whenever there is a CallbackEvent.

It has a staggering amount of widgets, to begin with; Dialogs, Panes, Menus, WYSIWYG editors, Buttons, Color pickers, Clocks, Layout Managers and a host of other things- just in the widgets department. Then there's the very handy encryption package, handy for hashing things coming to and from the server-side, the Drag-n-Drop package which works with nearly any element on the page, the essential Collections API with Java-like iterators and whatnot, and of course the powerful  proper Ajax functionality with several bells and whistles of its own.<BR><BR>Apart from the sheer amount of functionality available in dojo, there are a few architectural differences compared to most other frameworks; Dojo uses namespaces.

You need to have AJAX functions, such as, creating an XMLHttpRequest object for your browser, then using the object requests for a JSP page or Servlet (in general, for an URL), get the response and use it in your JSP web pages. For this, what I usually do is, I create a JavaScript file with all these functions and include this .js file in my web pages using a <script> tag, and use the functions mentioned there. This is a very common technique of using AJAX with JSP, and this is almost the same for PHP.
