sendError() clears response and triggers error page processing
You can specify your own page/servlet for this specific error code
with error-page element in your web.xml.

If you want to keep your message, just use "setStatus()" and return.
If you want to clear response before printing your message, call
ServletResponse.resetBuffer().

Beware that if you have user-provided data in your "text/plain"
response, I would recommend you to specify an explicit charset (e.g.
ISO-8859-1 in your case). If charset is not mentioned in Content-Type
header of an HTTP response, some browsers may start guessing and it
may lead to security issues.
