Another cause can be demonstrated with the following scriptlet code ...
if (session.getAttribute("articles") == null) {
response.sendRedirect("controllerServlet/home");
}
if (session.getAttribute("siteState") == null) {
response.sendRedirect("controllerServlet/home");
}
The second if is tested even if the first if is true. If the second if is
true another sendRedirect is attempted causing the error. It should be
coded as ...
if (session.getAttribute("articles") == null) {
response.sendRedirect("controllerServlet/home");
return;
}
if (session.getAttribute("siteState") == null) {
response.sendRedirect("controllerServlet/home");
return;
}

I have seen this when trying to write headers on an already flushed response
(hence "committed"). By moving my header writes up above the data write
for the post response, i avoided the problem.
I think this only came up when i went from tomcat 4 to 4.0.4, but its been
awhile now.

server !!
