So what is the correct way to redirect? I have started using relative links
to redirect and it seems to fix the problem. Is this just coincidence, or
is there an explanation for that?

If you webserver is serving in /usr/local/apache/htdocs, you are redirecting
to /usr/local/apache/htdocs/login.jsp, which is handled in this example by
apache, who doesn't know anything about jsp files. (that's why you got
tomcat in the first place...)
