We have this in our spring controller...

response.setContentType("text/html; charset=UTF-8");
Writer writer= response.getWriter();
if(bText) {
	writer.append("<html><head><meta http-equiv=\"Content-Type\"
content=\"text/html; charset=UTF-8\">\n</head>\n<body>\n");


if(bText) {

And the funny thing is that it seems to work... but only for straight
tomcat. I will make a confession - I do mainly .net these days and my
java (particularly web) is lacking in any real depth of understanding.
So I am guessing from your comments that the default content type of
tomcat is text/html? That is what we get with straight tomcat...
In any case, if this code is wrong then can someone give me a
suggestion to make it right?
Thanks again.
