The default servlet for Tomcat is declared in $CATALINA_HOME/conf/web.xml :
<servlet>
<servlet-name>default</servle...
Therefore, static content is rendered by the default configuration unless you override it with your own definitions.
If you want to allow directory listing, just change the listing parameter to true :
<init-param>
<param-name>listings</para...
Change the welcome-file-list to display a default page in lieu of a directory listing:
<welcome-file-list>
<welcome-file>home.xhtml</...
Welcome pages are defined at the Web application level.

This is a simple JSP custom tags library with tag body. Just like the JSF counterpart , it splits a string and repeats the body for each word, i.e., with this markup:
<%@ taglib uri="http://custom.tag.com/demo" prefix...
output:
<html>
<body>
<p>Hello Tigger!</p>

In an HTML page, elements can overlap because of position styles. When there's an overlap, elements coming later in the HTML code are displayed on the top. This can be altered by specifying z-index in the CSS. Elements with higher z-index are placed on the top.
However , z-index only works for elements that are not static positioned. Static positioned elements are always at the bottom compared to relative , fixed and absolute positioned elements.
This is a test page:
<!DOCTYPE html>
<html>
<head>
<style t...
Effects of z-index can be tested by adding it to the elements, for example:
<div id="bg" class="big" style="z-index: 3"></div>...

This is a simple example to demonstrate the templating power of JSF facelets. If you've used struts tiles before, you'll recognize the simplicity of templating with facelets. I've stripped out everything else except the pages themselves, just to put our focus on facelets. This is a Maven based project, and you need Tomcat (or any servlet container) to run the resulting webapp. To begin with this is the list of files:
./pom.xml ./src/main/webapp/home.xhtml ./src... I left faces-config.xml in there for completeness sake, it may not be needed. The Maven POM ( pom.xml ): <?xml version="1.0" encoding="UTF-8"?> <project... Web app configuration ( WEB-INF/web.xml ): <?xml version="1.0" encoding="UTF-8"?> <web-app... Empty WEB-INF/faces-config.xml : <?xml version="1.0" encoding="UTF-8"?> <!-- Thi... index.jsp is simply a redirect to home.jsf : <% response.sendRedirect("home.jsf"); %>...

The PHP function file_get_contents reads the entire contents of a file into a string, while the function file reads a file into an array.
file_get_contents('filename') is equivalent to implode('', file('filename')) :
<?php

It's probably more useful to make the JavaScript executor a bookmarklet. That way it gains access to the page on which it is invoked. Therefore, more helpful while debugging. Here's the code:
<html>
<body>
<a href="javascript:(funct...
Or, you can add this link to your bookmarks, name it "JS Executor". For a full featured JavaScript console, you may need Jash
