You should check the headers his browser sent you, you will be able to
understand which file he support, if he supports HTML then give it to him,
else is WML is supported the send the WML

if (request.getHeader("Accept").lastIndexOf ("wml") != -1)

    send WML
else
    send HTML

String userAgent = request.getHeader("user-agent");

You can use this value to determine what the client device (or browser)
is, including the version number.
