Flush a string to the browser as a file?

Question

How can I flush a string to the browser and make the browser save it like a file?
This is what I've got so far:
String info = "somthing funny here";
response.setContentType("text/plain");
response.setHeader("Content-Disposition", "filename=message.txt");
ServletOutputStream os = response.getOutputStream();
InputStream is = <somehow get t String info input stream?? >
int j = 0;
while ((j = is.read()) != -1) {
    os.write(j);
os.flush();
os.close();Thanks!

Try changing this:
response.setHeader("Content-Disposition", "filename=message.txt");to this:
response.setHeader("Content-Disposition", "attachment; filename=message.txt");
