facet
elements, which are allowed after the
component-class
elements. See

Basic Requirements of a JavaServer Faces Application
In addition to configuring your application, you must satisfy other requirements of
JavaServer Faces applications, including properly packaging all the necessary files and
providing a deployment descriptor. This section describes how to perform these adminis-
trative tasks.
JavaServer Faces applications can be packaged in a WAR file, which must conform to
specific requirements to execute across different containers. At a minimum, a WAR file
for a JavaServer Faces application must contain the following:
• A web application deployment descriptor, called
web.xml
, to configure resources
required by a web application
• A specific set of JAR files containing essential classes
• A set of application classes, JavaServer Faces pages, and other required resources,
such as image files
A WAR file may also contain:
• An application configuration resource file, which configures application resources
• A set of tag library descriptor files
For example, a Java Server Faces web application WAR file using Facelets typically has
the following directory structure:
$PROJECT_DIR
[Web Pages]
+- /[xhtml documents]
+- /resources
+- /WEB-INF
+- /classes
+- /lib
+- /web.xml
