| ChartServlet | | public class ChartServlet extends HttpServlet (Code) | | This Servlet returns image files of diagrams to be embedded in HTML/JSP
pages. The Servlet expects the following parameters:
- "imageType" Parameter (either GET or POST), one of "gif", "jpeg", "png"
- defines the image format to be returned
- "chart" Attribute (stored in SessionContext),
DefaultChart
object to be rendered
This class will be extended to allow easier rendering without assembling
the whole DefaultChart object. If the ChartServlet is deployed correctly
you can embed it e.g. with
<img src="/charting/ChartServlet?imageType=gif" alt="PieChart as GIF Image">.
