My problem is simple: in my XML data, a timestamp is provided as a long integer (number of milliseconds since the "the epoch"). When I do XSLT, I want to display it as a readable string, such as "Mon Nov 01 18:08:48 CDT 2010". After hours of struggle, I found: It's not so easy to get the job done with JDK 1.6 There are tons of garbage on the web in this space (suggestions, code snippets that simply don't work) Simple Xalan extension functions was the only resource that's somewhat informative. Even there some of the examples don't work. Below is a list of what worked and what didn't. This works:
<xsl:stylesheet version="1.0" xmlns:xsl="h...This does not (providing long value to Date constructor):
<xsl:stylesheet version="1.0" xmlns:xsl="h......

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. The tag renders
<ui:param name="extra" value="el interpreted"/> ...as
<h3>my:foreach</h3> <ul class="css class" extra...These are the files: The tag handler ( src/main/java/com/example/ForeachTagHandler.java ):

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

Facelet tag library descriptors can be specified in one of two ways: In web.xml , as <context-param> :
<context-param> <param-name>javax.faces...where javax.faces.FACELETS_LIBRARIES is interpreted as a semicolon ( ; ) separated list of paths, starting with "/" (without quotes). Each entry in the list is a path relative to the web application root, and is interpreted as a facelet XML tag library descriptor. The parameter facelets.LIBRARIES is an alias to javax.faces.FACELETS_LIBRARIES for backwards compatibility reasons. Via auto-discovery, by placing the XML tag library descriptor within a jar on the web application classpath (for example, under the folder WEB-INF/lib ). The file should have a name suffix .taglib.xml , and be placed in the META-INF folder of the JAR file.

In this example I'll add a parameter to a facelets template. The example contains three tabs, each tab points to a different page. The tab control is shared among all pages, therefore, it is put in the template. Starting from the simple facelet example , make these additions: Create a new template WEB-INF/templates/tabs.xhtml :
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Stric...Add a page for the about tab ( about.xhtml ):
<?xml version="1.0" encoding="UTF-8"?> <ui:comp...Add a page for the news tab ( news.xhtml ):
<?xml version="1.0" encoding="UTF-8"?> <ui:comp...Add a page for the partner tab ( partner.xhtml ):
<?xml version="1.0" encoding="UTF-8"?> <ui:comp...Build and re-deploy the application. Launch the browser and load page http://localhost:8080/facelet-demo/about.jsf . This is a screenshot:
