And the tag is closed..
The end of the much loved (and hated) tag in HTML
String intern() function and String Pool
The Java programming language requires that identical string literals (that is, literals that contain the same sequence of code points) must refer to the same instance of class String. In addition, if the method String.intern is called on any string, the result is a reference to the same class instance that would be returned if that string appeared as a literal.
XPath for XML
XPath is a language used to navigate through the XML document. It’s used to identify elements in the XML document. It is so limber that technologies like XQuery and XPointer are built on it. XPath uses path expressions to select nodes or node-sets in an XML document. These path expressions look very much like the expressions you see when you work with a traditional computer file system.
renderSnake – Better Way to create HTML
We live in an age where everything is open and innovations spring out every second. All those algorithms, all those concepts and all those frameworks are easily avalable to he who is willing to look. Unless you are not staring down from the tip of the cutting edge, you can pretty much get help on any problem. If someone had a similar problem before and you have the solution available, why re-invent the wheel..
URL, URI & URN.. cakewalk? Not for me atleast..
I have always been confused on the difference between the 3 most popular acronyms in web based computing – URL, URI and URN. The concept always seemed to evade me..
This post is more of a ‘talking to myself’ thing. I can almost imagine me reading this months from now, and feeling grateful that I finally wrote this down.
A Requiem for Marker Interfaces
Having written about Java serialization previously, I thought I’d put in some research into the concept of ‘Marker Interfaces’ or ‘Tag Interfaces’. Well, getting matters straight, technically, the word ‘Marker’ is an invention of bloggers and technical writers. Java specification says nothing about an interface being a ‘Marker Interface’. You won’t find the word ‘Marker’ at all..
Richfaces migration diaries
I always wanted to do this. I always wanted to write down a detailed description of the work I do. So, here’s the deal, my task was to migrate a web application running on RichFaces 3.X to RichFaces 4.X.
Simple and clean application running on JBoss 5. Just a couple of pages and quite many validations happening with JavaScript.
Composite Spacer Component for RichFaces 4
I have been working with richfaces 3.X.X and recently did a migration to richfaces 4.X.X. Many changes had to be done. Many tags got renamed, many properties suffered similar fate and some tags were retired.
JSF 2.0 Resources Concept
JSF 2.0 has introduced a wonderful concept for easy storage and easy retrieval of resources for a particular project. The project resources like css stylesheets, images and JavaScripts can be stored under a folder named ‘resources’ in the root of the web application.
Copy & Paste
A neat strategy to override the default “Copy & Paste” behaviour to modify the clipboard.
