title: How to replace com.sun.image.codec.jpeg.JPEGImageEncoder in this code?
body: <p>I have used <code>com.sun.image.codec.jpeg.JPEGImageEncoder</code> to handle JPEG images, like charts and others, in my webapp. Now, I am updating my machine to use JDK7, but this version deprecated this class. Below is the code that I need to change:</p>
  
  <pre><code>public void processChart(HttpServletRequest request, HttpServletResponse response)
      throws ServletException, IOException {
      response.setContentType("image/jpeg");
      out = response.getOutputStream();
      response.setHeader("Pragma", "no-cache");
      response.setHeader("Cache-Control", "no-cache");
      response.setDateHeader("Expires",0);
      try {
          int w = Integer.parseInt(request.getParameter("WIDTH"));
          int h = Integer.parseInt(request.getParameter("HEIGHT"));
          java.awt.image.BufferedImage ChartImage = new java.awt.image.BufferedImage(w,h,java.awt.image.BufferedImage.TYPE_INT_RGB);
          java.awt.Graphics2D ChartGraphics = ChartImage.createGraphics();
          Chart c = getChart(request);
          c.setSize(w,h);
          c.paint(ChartGraphics);
          // CODE BELOW TO CHANGE...
          com.sun.image.codec.jpeg.JPEGImageEncoder encoder = 
                                   com.sun.image.codec.jpeg.JPEGCodec.createJPEGEncoder(out);
          encoder.encode(ChartImage);
      } catch (Exception e) {
          e.printStackTrace();
      }
  }
  
  private Chart getChart(HttpServletRequest request) {
      chartLoader loader = new chartLoader(null);
      loader.paintDirect = true;
      java.util.Enumeration ps = request.getParameterNames();
      while (ps.hasMoreElements()) {
          String name = (String) ps.nextElement();
          loader.setParameter(name,request.getParameter(name));
      }
      // create Chart
      Chart chart = loader.build(false,false);
      Chart.tmpImage = new java.awt.image.BufferedImage(200,200,java.awt.image.BufferedImage.TYPE_INT_RGB);
      return chart;
  }
