In JSP you output the web application context path with:
${pageContext.request.contextPath}
Facelets are not JSPs, and there's no pageContext . So the above does not work.
But in facelets you can use request directly:
${request.contextPath}
For example, a link to the root URL:
<a href="${request.contextPath}">Home</a>
Servlet request URL:
<h2>#{request.requestURL}</h2>

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.

Spring MVC 3.1 can send either JSON or HTML response on the same URL, depending on the type of response requested. With this mechanism, a page can be sent when directly requested from a link, but a JSON response can be sent in response to an AJAX request. This is the controller code:
package com.example; import java.util.Map; ... In the above example, JSON response will be sent when the HTTP request contains header "Accept: application/json". HTML response will be sent then the header is "Accept: */*", or "Accept: text/html", or anything else. You can add a limitation that the HTML response does not produce "application/json". But then the question is which response will be sent when the HTTP header is "Accept: */*"? Both methods will...

When you insert an attribute in JSP:
<%@ taglib uri="http://tiles.apache.org/tags-tiles...
you must define the attribute in tiles definitions:
<definition name="/home" template="/WEB-INF/templa...
Otherwise you'll get runtime exception.
The ignore attribute, which defaults to false , will suppress the runtime exception when the attribute is not defined in tiles definition:
<%@ taglib uri="http://tiles.apache.org/tags-tiles...

This is a simple Hello World application with Spring 3 MVC. Like the default Apache HTTPd welcome page, it displays " It works! " when successfully deployed. The sole purpose is to show the minimum elements needed to setup Spring 3 MVC.
I use Maven since it's so much easier than downloading the dependencies manually.
Directory layout:
./src
./src/main
./src/main/webapp
./src/...

Tomcat allows you to create multiple server instances for the same installation. The installation directory is identified as CATALINA_HOME , the instance directory is identified as CATALINA_BASE . Here are the steps: Create a base directory for the new instance, for example: /home/nogeek/tomcat1 . Create the subdirectories:

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...

Facelet templates can be nested, for example, a page can use a template which inherits from another template. To demonstrate this, let's start from the simple example and make these additions:
Add a place holder for CSS style sheets in WEB-INF/templates/default.xhtml :
<h:head>
<title>Facelets Template Demo</tit...
Add a derivative template ( WEB-INF/templates/default-style.xhtml ) which provides CSS:
<?xml version="1.0" encoding="UTF-8"?>
<ui:comp...
Add a page that uses the styled template ( home-style.xhtml ):
<?xml version="1.0" encoding="UTF-8"?>
<ui:comp...
The only difference between this file and home.xhtml is the template being used.
Compare the display of the pages home.xhtml and home-style.xhtml .
