Fri, 23 Jun 2006 13:15:00 EDT

This article will describe our experiences with developing a Java-based instant messenger application using Jabber/XMPP (Extensible Messaging and Presence Protocol) - a free, open and public protocol and technology for instant messaging. According to the Jabber Software Foundation, 'Under the hood, Jabber is a set of streaming XML protocols and technologies that enable any two entities on the Internet to exchange messages, presence, and other structured information in close to real-time.'

Web Conferencing Using the Java Media Framework (JMF)

Thu, 05 Aug 2004 00:00:00 EDT

Java Media Framework (JMF) is used to develop the browser-based Web conferencing application. In this architecture, the client uses two JMF applets - one for capturing video/audio from a Webcam and the other for playing video/audio feed. The capture applet continuously captures video/audio feed for a specified length of time (e.g., 10 seconds) and saves it locally in a file. This file is uploaded to a Web server using an upload servlet.

Medical Image Conversion

Fri, 02 Jul 2004 00:00:00 EDT

In this article we'll discuss the conversion of image formats using Sun's Java Image I/O (ImageIO) and the NIH ImageJ APIs. The image formats of interest are DICOM, JPEG 2000, PNG, and TIFF. These formats are widely used in medical applications; however, most of the disciplines in medicine are standardizing on DICOM. A single API, ImageIO or ImageJ, supports the reading and writing of limited image formats.

Developing Web Portals in Jetspeed Using JSP

Thu, 03 Jun 2004 00:00:00 EDT

A Web portal is an application that aggregates multiple Web applications on a single Web page. Popular examples of portals are My Yahoo (my.yahoo.com) and My MSN (my.msn.com). These portals allow users to aggregate multiple Web applications (like Stock Quote, News, and Weather). In addition these portals allow users to personalize and customize the presentation and content of the individual Web application.

Model-View-Controller based Plug-able Declarative Framework

Tue, 11 May 2004 00:00:00 EDT

A Model-View-Controller based Plug-able Declarative Framework (MVC-PDF) will be described, in which developers use the full power of ColdFusion MX (CFMX) components to create MVC applications. The declarative nature of the framework will allow the controller and the model to be specified declaratively in configuration files, versus custom coded in ColdFusion.

Data Driven Web Graphics with SVG: A Declarative Approach

Thu, 18 Apr 2002 00:00:00 EDT

Scalable Vector Graphics is likely to revolutionize the way Web graphics are rendered, stored, manipulated, and associated with content. SVG, a 2D portable Web graphics standard recommended by the W3C in September 2001, is an XML-based standard for specifying both graphics and content. SVG replaces server-side image file creation or applet-based graphics with client/Web browser-based rendering of images.
