Sometimes its useful to expose the version of your web application - I find it useful so vsConsole can display the version of the deployed application for each environment on the dashboard. If you build your app with Maven, you can use this code to get the version, and simply wire up a controller/rest endpoint to return it as text/plain.

	private static final String VERSION_KEY = "version";
	private static final String POM_PROPS_PATH_MF = "/META-INF/maven/{0}/{1}/pom.properties";

	public static String getMavenWarVersion(ServletContext context, String groupId, String artifactId) {
	String resourceName = MessageFormat.format(POM_PROPS_PATH_MF, new Object[]{groupId, artifactId});
	Properties properties = loadProperties(context.getResourceAsStream(resourceName));
	if (properties != null) {
	return properties.getProperty(VERSION_KEY);
	}
	return "unknown";

Accessing the PrimeFaces artifacts via maven.

	In section 2 of the documentation (http://www.primefaces.org/documentation.html), it shows how you can define the primefaces repository in your maven pom.xml (or ~/.m2/settings.xml):

	<repository>
	<id>prime-repo</id>
	<name>Prime Repo</name>
	<url>http://repository.primefaces.org</url>
	</repository>

	If you are using maven in an organisation you would be better off setting up a repository manager such as NEXUS and configuring that with the primefaces repository. Then, your developers just configure this nexus repository as a mirror of everything in their ~/.m2/settings.xml and everything is transparent.
