Our custom tag, as implemented in the previous note , is broken when a template is used.
Create a template file ( home-template.xhtml ):
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Stric...
and a test page that uses it ( home.xhtml ):
<?xml version="1.0" encoding="UTF-8"?>
<ui:comp...
Then request the page with URL: http://localhost:8080/facelet-demo/home.jsf?name=Jack .
You'll find that our hello tag works inside ui:repeat but fails to get the value defined by ui:param ! What's the problem? Our hello tag implementation evaluated the EL with the wrong EL context!
This is the corrected implementation:
package com.example;
import java.io.IOExcep...

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:...

Create the stuff you want to manufacture with the factory:

public class Junk {

Tell Tomcat to use your factory. Create file context.xml and put it under the directory META-INF of your web application:
<Context>
<Resource name="/find/junk/here"
...
Note that beside name , type and factory , you can put any arbitrary attribute in the Resource element.
Access the thing with JNDI:
<%@page language="java" import="javax.naming.*,tc....
The server side log looked like this:
INFO: jndiName: here
INFO: name: scope, value: ...
Also note that, in contrast to Tomcat documentation , resource-ref is not needed in web.xml .

Use the siblings function to find all siblings of the current jQuery object:
$(this).siblings()
which is equivalent to:
$(this).parent().children().not(this)
Or, use an optional selector to further limit the selection of siblings:
$(this).siblings('li .hilighted')
Test page:
<!DOCTYPE html>
