I have a InputStream of an image in string format. How to display that image in the browser using servlets?

This is the (start of the) string.

*"I have a inputstream of an image in string format."* Is it base 64 encoded? How did you end up getting an image as string in any case? — Andrew Thompson, Dec 04 '12 at 09:45
No, I tried to use ImageIO but I don't have any bytes of image, I have only this inputstream. Please suggest me how to display this image. — Narasimha, Dec 04 '12 at 09:48

You need write the image as a byte array to the response's output stream. Something like this:

byte[] imageBytes = getImageAsBytes();
response.setContentType("image/jpeg");
response.setContentLength(imageBytes.length);
response.getOutputStream().write(imageBytes);

Then in you JSP you just use a standard img element:

<img src="url to your servlet">
