Hi,
You are mising something here. You shouldn't mix anything.
The servlet should return only a html page that has an (static or dinamic)
image one it.
The browsers' job is to make another request to the server and get the
image.
So put in your servlet something like:
out.println("<img
src=\"http://www.somewhere/servlet/ImageGenerator?id=234\">");
Than in this ImageGenerator:
res.setHeader("pragma","no-cache");
res.setHeader("content-encoding","image/gif");
res.setContentType("image/gif");
GifEncoder encoder = new GifEncoder(image,out);
encoder.encode();
res.flushBuffer();
Hope this helps a little bit.
p.s. It can be done in one servlet too.
Best wishes,
Andras.
