Make servlet,
January 14, 2010 at 7:38 PM

Hello!

You can generate a special servlet, what give back an image.

I've found a next example with Google:

public class ChartViewer extends HttpServlet
{
public void doGet( HttpServletRequest request, HttpServletResponse response )
throws ServletException, IOException
{
// get the chart from storage
JFreeChart chart = (JFreeChart) session.getAttribute( "chart" );
// set the content type so the browser can see this as it is
response.setContentType( "image/jpeg" );

// send the picture
BufferedImage buf = chart.createBufferedImage(640, 400, null);
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder( response.getOutputStream() );
JPEGEncodeParam param = encoder.getDefaultJPEGEncodeParam( buf );
param.setQuality( 0.75f, true );
encoder.encode( buf, param );
}
}
