This is an example that uses tag handler, UI component and renderer together to support a custom taglib. The main purpose is to show how these components play together.

In the simple taglib example , I used a tag handler class to implement a taglib. This is an example to implement a taglib with a UI component. The purpose is to use a custom tag to split a string and print each part in a separate paragraph, i.e., print <p>john</p> <p>steve</p> <p>mike</p> with custom tag <my:foreach> : <my:foreach var="who" value="john steve mike"> ... These are the files: pom.xml <project xmlns="http://maven.apache.org/POM/4.0.0"... src/main/java/com/example/UIForeash.java : package com.example; import java.io.IOExcep... src/main/resources/META-INF/faces-config.xml : <?xml version="1.0" encoding="UTF-8"?> <faces-c... src/main/resources/META-INF/foreach.taglib.xml : <?xml version="1.0" encoding="UTF-8"?> <facelet... How to use: Put the JAR file generated by the above project in the WEB-INF/lib folder of the web app. If the web app is a Maven project, just add the taglib project as a dependency:...

The tags XML transform tags apply XSLT to XML documents. The XML document may be specified as the doc attribute or enclosed as the body of the <x:transform> tag. Optional <x:param> tags may be used to specify parameters for the XSLT. <x:transform> Syntax: <x:transform doc="XMLDocument" xslt="XSLTStyle... or, include the XML document in the body: <x:transform xslt="XSLTStylesheet" [docSystem...

IE and firefox both support client side XSLT. This can be done by inserting an xml-stylesheet into the XML file, which would trigger the browser to apply the XSL to the XML document and generate a transformed page: <?xml version="1.0" encoding="utf-8" ?> <?... Or, it can be done more dynamically with client side JavaScript. However, IE and FF offer different APIs for XSLT. Below is my attempt to bridge the differences. It's been tested to work for IE 7.0, FF 2.0 and Opera 9.0.2. function XSLT(url) { var xslt = false; ... The following HTML page shows how to use it: <HTML> <HEAD> <SCRIPT language="JavaS...
