This link on SourceForge has a list of sample Struts applications. I used to tell people to download Beer4all, but the last time I tried to run it, it was very buggy. Just pick one from the list and you'll see what others have done with struts.
Sad to say, it appears that a lot of them have been vandalized, meaning someone has gone in and removed or rearranged tags just enough so that it doesn't work. I found that to be the case for struts-cookbook.
This link seems to be better. [ January 18, 2007: Message edited by: Merrill Higginson ]
