You need to create a Reply, according to the level of protocol used by using
Reply = req.makeReply(status);
where status is one of the HTTP status value as defined in 
[org.]w3c.http.HTTP.java (an error value is 4xx, a OK value is 2xx...)
Then you have to fill the value needed to describe what you will fill in 
this Reply. ex:

	    InputStream   in;
	    reply = req.makeReply(HTTP.OK);
	    try {
		mt = new MimeType(c.getContentType());
	    } catch (MimeTypeFormatException me) {
		mt = MimeType.TEXT_PLAIN;
	    return reply;

	  reply.setContent("18 bytes length msg");

If you can provide good caching information, do so, as it will help 
caches to handle that kind of reply.
