I have 2 user roles - user and admin , if I go to a url where any authentication is needed and I am not authenticated - I get redirected to the login page, which is fine.
However, if I am logged in as user, and I try to access an admin only page, I get the home page displayed, but the url stays the same. I want to actually redirect to the home page rather than just display it.
So is there any way to make the accessDeniedPage method redirect, because as I said the home page is displayed but the url does not change.
If you are authenticated (logged in), and you attempt to invoke a URL that you are not authorized to access (that is, you don't have any of the roles associated with that URL pattern in web.xml), then you should get an "HTTP 403 - Forbidden" response page back.
You can create your own custom 403 page and define it in web.xml. Please note, however, that since it is the web application server that's displaying that page and not the application itself, the standard request routing may not be followed. Or, in other words, make things like "403" pages be plain HTML or JSP. Frameworks that go through a dispatching servlet such as JSF or Struts might not work properly.
If, as I fear you are saying, you actually want to simply bounce an offending user straight back to the home page without any sort of error message, I don't recommend that. It's confusing.

It would give a normal human mental abilities to rival mine. To think it is just a tiny ad:
