Image upload from servlet to another servlet.

I am trying to send an image that it local to a servlet to another servlet which should download the image.
the first servlet does something like:
           
           File imFile = new File("/home/pdutta/thumbnails/Image1.jpeg");            
            BufferedImage bi= ImageIO.read(imFile);
            if(bi == null)
                  sm_cat.debug("bi is null");
           
           
            ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
            if(ImageIO.write(bi,"jpeg", byteArrayOutputStream))
                  sm_cat.debug("Wrote to the stream");
           
            byte[] imageByteArray = byteArrayOutputStream.toByteArray();
           
            OutputStream os = httpcon.getOutputStream(); // httpcon is the HttpURLConnection.
            os.write(imageByteArray,0,imageByteArray.length);
            os.flush();
            os.close();
           
            httpcon.connect();  


The receiving servlet does something like:
            //in the doGET method.
            InputStream is = request.getInputStream();
            String filePath = "/home/pdutta/procThumb/" + strFilename;
            FileOutputStream fs = new FileOutputStream (filePath);
           
            int c;
            sm_cat.debug("Available bytes are : " + is.available());
            while ((c = is.read()) != -1)
            {
                  fs.write(c);
            }

I am somehow always receiving 0 bytes. What am I doing wrong?Start Free Trial
