Randy,

Because you are doing an RequestDispatcher.include() the my.jsp page is served up in the same HTTP Response that is setting the
cookies.
my.jsp then looks in the Request for the cookies and doesn't find them there, because it's looking at the same HTTP Request that was
originally sent to your login servlet.

All the forwarding here ( or including in this case ) occurs on the server side. You need to do a round trip to the browser to set
the cookies, so that they will be included on subsequent requests. i.e. something like :
 response.sendRedirect( "/my.jsp" );

This will send a 302 response to the browser, as well as the correct response headers to set your cookie values, so that they are
included as request headers in the redirected request to my.jsp


Steph

P.S. for what it's worth I think the best explanation of all you need to know about HTTP methods, headers, cookies, etc.. comes in
the first few chapters of an O'Reilly book called "ASP in a Nutshell" - just the thing for a Tomcat users list ;)
