Image to JSP file

Question

I need to display an image to JSP file. This image is generated in Java file and returned as BufferedImage object to JSP.
The image generated through Java file is not getting stored anywhere. I just need to pass the Image object to the JSP file.
Please let me know how is it possible.

Hello, this is a brief code of a simple web service I coded sometime ago, and tested using asp & jsp.
Servlet class:
public class ImageServlet extends HttpServlet{
public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException{
try{
CheckProducer checkProducer=(CheckProducer)Class.forName(request.getQueryString()).newInstance(); //class name entered in url eg. com.orly_otero.Images.pngImage
byte[] out_stream=checkProducer.createCheck("dummy"); //Your image-generating class.
ByteArrayOutputStream baos=new ByteArrayOutputStream();
baos.write(out_stream, 0, out_stream.length);
//System.err.println(out_stream.length); //Image Size.
baos.writeTo(response.getOutputStream());
response.setContentType("image/png");
catch(Exception e){
throw new ServletException(e);
More important code of com.orly_otero.Images.pngImage
public byte[] createCheck(String name) throws IOException{
ByteArrayOutputStream stream=new ByteArrayOutputStream();
try{
ImageIO.write((java.awt.image.BufferedImage)image, "PNG", stream);
catch (Exception je){
throw new IOException(je.getMessage());
return stream.toByteArray();
image contains your awt drawed image.
Hope this help.
