An Introduction to JSTL
Author :
Ramaswamy
Date : Thu May 22nd, 2008
As J2EE programmers, we are familiar with Servlets , JSP and JavaBeans. Any JSP page should encapsulate the business logic in a bean and invoke it by using jsp:useBean tag. Till recently, a combination of Servlets, JSP and beans was the standard practice. But, the JCP realeased an API for enabling programmers to create custom tags and use them in their JSP pages. The difference between javabean and java custom tags was that, though both made use of java classes, tags can be used by non-programmers also without knowledge of Java programming, just as they would use html tags.( From a programmers perspective,however, a much more important distinction is that tags are specific to the page in which they are created while javabeans are general. )
Getting Started with Flex 2.0

Date : Thu May 22nd, 2008
Flex2 is the latest RIA technolgy based on MXML and Flash.Originally from Macromedia, this software is now being provided by Adobe, as Adobe has recently acquired Macromedia. The Flex2 software was given in DeveloperIQ CD in August-2006. That edition carried a very interesting and informative interview with Dave Gruber of Adobe by the editor Mr.Ramdas. Flex2 is being positioned and promoted as a better technology than Ajax. ( this is the impression that we gain, from their advertisements in JavaLobby site).
The aim of this introductory tutorial is to explore the technology at a very basic level. However, what we see by these basic experiments is that it is just like DotNet Framework and ASP.net , atleast so far as naming of controls etc are concerned and partly like an applet( it is executed in client-side).
