Image Upload Servlet not working in Chrome, but works in other browsers

I have tested this servlet开发者_开发技巧 and it works well, except in Google Chrome it jsut doesn't display image. What could be wrong in this example code that makes Chrome not to display image?

I suspect that the following line was missing:

response.setHeader("Content-Length", String.valueOf(image.length()));

Some browsers may namely be picky on that.
