Use a Filter part of Servlet 2.3. I assume you could map all requests

Ted,
Your example says this:
To seed the textarea from the form bean, you could code something like:
textarea name=article rows=15 cols=60 wrap=soft/textarea
But there is something additional to set the initial value from the form
bean, correct?
textarea name=article rows=15 cols=60
Your default action could be implemented by either extending
ActionServlet, or using a Filter (part of Servlet 2.3, not Struts-related),
so Struts can handle your requirements nicely I suspect.
