Description Olaf Meske 2007-08-29 03:56:43 UTC
The class org.apache.catalina.connector.Response

resets the internal hold coyoteResponse and outputBuffer during reset():

    public void reset() {
        if (included)
            return;     // Ignore any call from an included servlet

but if anyone has already set the characterEncoding (e.g. to UTF-8) and already
got the writer, than all following invocations of request.setCharacterEncoding()
will do nothing, because the internal save flag for usingWriter is not reseted.
This is very annoying, because the coyoteResponse.reset(), resets the
characterEncoding to iso8859-1. So I have no change to change/reset the
charaterEncoding to UTF-8.
I'll think if you reset the response, you should also reset the usingWriter flag
or add another special flag, that works with this circumstances.
