NOTE: Download the war and deploy it on ie.g. a tomcat server!
If you want also to test the database examples create a database and configure it in the context.xml file of the war (pack/unpack it with zip) and put the database driver jar in the common/lib directory of the tomcat before starting it.

If you deployed the war on "localhost", try to access the examples as below:
http://localhost/jet-examples-webapp-<version number>/
e.g.: http://localhost/jet-examples-webapp-2.5.0/
