hi,

   There is an example to generate html output in webapps of jasperreport jar file.Anyway the following is the code for html output:

JasperPrint jasperPrint =JasperManager.fillReport(jasperReport, parameters, conn);

Map imagesMap = new HashMap();
        req.getSession().setAttribute("IMAGES_MAP", imagesMap);

        JRHtmlExporter exporter = new JRHtmlExporter();

        exporter.setParameter(JRExporterParameter.JASPER_P RINT, jasperPrint);

        exporter.setParameter(
            JRExporterParameter.OUTPUT_WRITER,
            resp.getWriter());

        exporter.setParameter(JRHtmlExporterParameter.IMAG ES_MAP, imagesMap);

                exporter.setParameter(
            JRHtmlExporterParameter.IMAGES_URI,
            "image?image=");


        exporter.exportReport();


You have to mention a imageservlet which has the following code:
public class ImageServlet extends HttpServlet
{



    public void service(
        HttpServletRequest request,
        HttpServletResponse response
        ) throws IOException, ServletException
    {


        Map imagesMap = (Map)request.getSession().getAttribute("IMAGES_MAP ");

        if (imagesMap != null)
        {
            String imageName = request.getParameter("image");
            if (imageName != null)
            {
                byte[] imageData = (byte[])imagesMap.get(imageName);

                response.setContentLength(imageData.length);
                ServletOutputStream ouputStream = response.getOutputStream();
                ouputStream.write(imageData, 0, imageData.length);
                ouputStream.flush();
                ouputStream.close();
            }
        }
    }


}

   just compile and run the code ,u can generate HTML o/p.

Thanks
