                                       javax.servlet.http.HttpServletResponse httpServletResponse)

                                       java.io.IOException
        Convenience method to call from a Servlet or JSP. This method will set the appropriate mime type and then export the chart as the response. We cannot overload encode(...) as it will create a compile time dependency with the HttpServletResponse Class which will require the J2EE libraries.
        Parameters:
        chart -
        httpServletResponse -
        Throws:
        ChartDataException
