For security reasons, only the servlet container can set the values returned
by methods like getRemoteUser(). Otherwise, an unscrupulous servlet author
could trick other servlets into displaying information they should not.
For your purposes, the easiest thing to do is set a request attribute instead:
RequestDispatcher rd = ...
req.setAttribute("username", "newuser");
rd.forward(req, res);
and read it in the second servlet:
String username =
(String) req.getAttribute("username");
