What I feel is missing is a simple simple simple tutorial.
I suggest the following as an initial scenario:
1) Use the existing skeleton-project as a starting point.
2) Remove any appserver-specific references.
3) Do not require the use of ant to build it, but instead simply provide it in war-ready (exploded directory) format.
4) Require and utilize only the functionality present in the bare-bones webwork.jar -do not include any other jar files in the war.
5) Walk the user through the creation of the formtest.jsp page indicating the expected behavior of each line and the resources upon which it depends ie: the template that will be used and the parameters being passed in each tag.
6) Explain the properties exposed in the FormTest bean and the validation that is occurring. Have the user provide further validation requirements for the comments field and observe the results.
6) Provide the views.properties as is and then have the user create a new .jsp page called expression.jsp and change the success mapping to point to that new page.
7) In the new expression.jsp page, have the user do something simple like this:
<%@ taglib uri="webwork" prefix="webwork" %>
You have reached the expression page indicating success!

Here is your comment:
This could be followed by more advanced tutorials - each one adding 2 or 3 more gems of webwork magic.
My 2 cents.
