a "welcome file" can be specified, which means a page that will be displayed
if no specific page is requested by the user (for example, when navigating to
http://www.someserver.com/myapp/).
In Tapestry 5, the deployment descriptor is somewhat unusual. This is what you will
see if you look into the web.xml file of one of the applications created in this book:

"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">

You can see that no servlets are defined in the Tapestry 5 deployment descriptor, and
this is unusual. Instead, there is a filter, which is configured and associated with a

or after a servlet is invoked.
