I think you need to protect /shibboleth-login (or if you use the webapp name in 
your deployment path, /jspui/shibboleth-login etc).

The Shibboleth code will then kick in when the user visits that URL, which is 
defined in the loginPageURL method of ShibAuthentication.java. Once 
authenticated, it bounces the user back to the URL, tomcat does its stuff, the 
servlet is used, the shib values read, and the user is logged in.

    public String loginPageURL(Context context, HttpServletRequest request,
            HttpServletResponse response)
    {
        return response.encodeRedirectURL(request.getContextPath()
                + "/shibboleth-login");
    }

As an aside, just in case anyone is interested, I've just finished developing a 
Java/Tomcat/DSpace Shibboleth solution that doesn't require the use of 
mod_shib+Apache. It isn't as mature as mod_shib (for example it doesn't 
currently cope with encrypted NameIDs), but it seems to work fine, and we're 
about to roll it out to our production servers.

Is it based on the OIOSAML Servlet Filter, so acts at the Tomcat Filter level 
rather than as an Apache module. If you don't currently front your tomcat 
instance with apache, it can simplify Shibboleth installation.
