The best way to create a Struts project in Eclipse is to import the struts-blank.war file that comes with the download. This file will be named differently depending on which version of Struts you're using, but it will always have the
word "blank" in the name and it will always be in the "apps" directory.
Just import it using the file-->import-->war file function in eclipse. The web project that's created will serve as a base project to which you can add your own artifacts.
