I'm using JavaMail to read a MimeMessage. One Part of the mail contains an
image (image/jpeg). I can create an InputStream for this image. But if I
simply write the bytes to the ServletOutputStream it'll only appear a
broken-image symbol.
How am I to implement writeImageBytes()? Currently I'm using:
response.setContentType("image/jpeg");
ServletOutputStream sos = response.getOutputStream();
// Part pa is the Part of the mail which contains the image
InputStream is = pa.getInputStream();
int c;
while ((c = is.read()) != -1) {
sos.print(c);
}
What is wrong with that? I can't imagine that it's so difficult...
thx in advance
Christian
