The Struts Wiki has the best collection of free tutorial links, so rather than duplicate them in
the Struts FAQ, we just refer you to
The Struts Wiki Tutorial Page.
Take your pick from any one of the ones listed. If you're using a particular
IDE such as NetBeans or Eclipse, you'd do well to Google "Struts tutorial xxxx" where xxxx is the name of your favorite IDE. Most IDEs have at least some support for Struts.
