JSJaC: JavaScript Jabber Client Library
JSJaC is a JavaScript Jabber Client Librarythat was built "to ease implementation of web based jabber clients. For communication with a jabber server it needs to support either HTTP Pollingor HTTP Binding."
To use the library you can check out examplesto see how you can do things like send a message:
if (aForm.msg.value== ''|| aForm. sendTo.value== '')
return false;
if (aForm.sendTo.value.indexOf('@')== - 1)
aForm. sendTo.value+= '@'+ con. domain;
try {
varaMsg = newJSJaCMessage ();
aMsg. setTo(newJSJaCJID (aForm.sendTo.value));
aMsg. setBody(aForm.msg.value);
con. send(aMsg);
aForm. msg.value= '';
return false;
} catch (e) {
html = "<div class='msg error''>Error: "+e.message+"</div>";
document. getElementById('iResp').innerHTML+= html;
document. getElementById('iResp').lastChild.scrollIntoView();
return false;
}
}
or handle presence:
varhtml = '<div class="msg">';
if (!aJSJaCPacket.getType()&& !aJSJaCPacket. getShow())
html += '<b>'+aJSJaCPacket.getFromJID()+' has become available.</b>';
else {
html += '<b>'+aJSJaCPacket.getFromJID()+' has set his presence to ';
if (aJSJaCPacket.getType())
html += aJSJaCPacket. getType()+ '.</b>';
else
html += aJSJaCPacket. getShow()+ '.';
if (aJSJaCPacket.getStatus())
html += ' ('+aJSJaCPacket.getStatus().htmlEnc()+')';
}
html += '</div>';
document. getElementById('iResp').innerHTML+= html;
document. getElementById('iResp').lastChild.scrollIntoView();
}
Since Jabber (XMPP) is taking over the world, it may be a nice tool in the toolbox.

JSJaC is a jabber/XMPP client library written in JavaScript to ease implementation of web based jabber/XMPP clients. For communication with a jabber server it needs to support either HTTP Pollingor XMPP Over BOSH(formerly known as HTTP Binding). JSJaC has an object oriented design which should be quite easy to use. Communication is done by using the XML HTTP Request objectalso refered to as AJAX technology. Your browser must support this.
A simple command-line tool to create the folders and helper files for a new JavaScript project/library. As a bonus, you can quickly create a website to promote your project.
When you start a new JavaScript library, how do you layout the source files, the tests, the distribution files? Do you have support scripts to generate distributions from source files? Run your JavaScript unit tests? Generators to create new unit test HTMLfiles?
This JavaScript client library allows you to make Facebook API calls from any web site and makes it easy to create Ajax Facebook applications. Since the library does not require any server-side code on your server, you can now create a Facebook application that can be hosted on any web site that serves static HTML. An application that uses this client library should be registered as an iframe type. This applies to either iframe Facebook apps that users access through the Facebook web site or apps that users access directly on the app’s own web sites. Almost all Facebook APIs are supported.
- No plugins like Flash or Java required.
- Popup blockers are no problem. The content expands within the active browser window.
- Single click. After opening the image or HTML popup, the user can scroll further down or leave the page without closing it.
- Compatibility and safe fallback. If the user has disabled JavaScript or is using an old browser, the browser redirects directly to the image itself or to a fallback HTML page.
jQuery UI is a set of themable widgets and interactions, built on top of the jQuery JavaScript Library, that you can use to build highly interactive web applications.
Just by adding this small JavaScript module to the end of your web pages, you get your form's submissions intercepted and, instead of sending request to the server in the usual way, they are done asynchronously and in an AJAX-style smooth way.
As long as it is a client-side library it will work with any server technology: ASP.NET, PHP, JSP, Classic ASP... and even with local HTM files.
I've included extensibility so that you can add easily your own progress indicators (several included) and show error messages the way you prefer (by default it shows an alert).
It's transparent to your server code and could be used to add AJAX capabilities to some applications without writting a single line of code.
Documentation is included.
Features summary
• No-code AJAXification of web apps
• Supports any server technology, including ASP.NET, JSP, PHP, ASP 3.0...
• In ASP.NET it supports all kinds of postbacks: direct and by code.
• Works in any modern browser that supports AJAX.
• Supports cross-posting of forms, that is, you can send the information to any web page in the same domain. If all your web pages have AJAXInterceptor included (for example, you include it in your master page or template) you can hace
• Respects your custom onsumit event handlers.
• Supports browser history so that your users can hit the previous button and get the last rendered page.
• Two versions of the module:
- AJAXInterceptor.js: full commented one. Useful for debugging purposes.
- AJAXINterceptor_r.js: reduced-size version. It downloads faster as it only is 2.6 kB in size. It's better to use this on production apps.
• Automatically show/hide custom progress indicators.
• Support for cancelling operations.
• Support for custom message displaying.
• Supports any form in your page
Obviously this is not substitute at all of full-fledged APIs like Microsoft's ASP.NET AJAX, PHPLiveX or AJAX.NET, but will let you add AJAX support to your apps in a few seconds and without writing any code. Just give it a try!
In the ZIP you will find teh module, a working sample with ASP.NET and a PDF with the help documentation.
This project is just for fun :-)
I will be very glad if you drop me a line in case you use AJAXInterceptor in any real-world application or if you enhance it with new features.

Google Web Toolkit (GWT) is an open source Java software development framework that makes writing AJAX applications like Google Mapsand Gmaileasy for developers who don't speak browser quirks as a second language. Writing dynamic web applications today is a tedious and error-prone process; you spend 90% of your time working around subtle incompatibilities between web browsers and platforms, and JavaScript's lack of modularity makes sharing, testing, and reusing AJAX components difficult and fragile.
GWT lets you avoid many of these headaches while offering your users the same dynamic, standards-compliant experience. You write your front end in the Javaprogramming language, and the GWT compiler converts your Java classes to browser-compliant JavaScript and HTML.
What is XSTM?
XSTM is a n open sourcelibrary which enables high performance object replication between processes. It is an object oriented Distributed Shared Memory, or a Distributed Object Cache.
XSTMhas similarities with technologies like Adobe Flex Data Services , JBoss Cache, Terracotta, Tangosol Coherence , ScaleOut , or IBM's ObjectGrid .
Our model is based on object shares, which work like file shares. When an object is added to a share, it appears on the other machines which have the same share opened. Modifications done to the fields of the object are from this point replicated between machines.
Read more in the project overview.
XSTMis made of three projects. The Java implementation is called JSTMand is the base from which
the other versions are derived. An adapted version made with Luciano, the
author of GWM , is available for GWT . It allowsthis library to be used in a browser. NSTM is a .NET port based on IKVM.
All implementations are compatible with each other so object replication can take
place e.g. between a Java server and a .NET Smart Client.
Django’s template language is designed to strike a balance between power and ease. It’s designed to feel comfortable to those used to working with HTML. If you have any exposure to other text-based template languages, such as Smartyor CheetahTemplate, you should feel right at home with Django’s templates.
