Please be sure to ask Struts questions in the Struts forum. I have moved this post there for you.

Its hard to guess what the problem is without some more code. Does your action returns "input" result in any way or is there any validation error when you reach this action??

When does the error appear actually?? If it occurs when you enter a URL into the browser, then tell us that URL otherwise if it happens when you submit a form, then please post the code of that form. I think the error appears when you try to list all students as validation happens in that case and since there is no "input" result defined, you get the 404 error message. You'll have to tell struts to skip validation in case of StudentAction.list() method. You can find more info on how to do that here...

basicStackHibernate doesn't have validation interceptor in it. If you had used the struts basicStack in your action that would've worked too (or the solution that I gave you earlier)...
