Question

I am generating an image in my servlet:

ImageIO.write(bufferedImage,"jpg" ,Outputstream)

But after deploying I am receiving an error that it can’t read the input file.

Answer 1

Long time ago I wrote the following code (it was taking the image stored as blob in database and writing it to the servler output):

public class ImageDB extends HttpServlet {
// ...
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
 // ...
byte[] bytes = blob.getBytes((long)1, (int)blob.length());

ServletOutputStream out = response.getOutputStream();
out.write(bytes);
out.close(); // Close stream
// ...

  }
