How to transfer a PDF from a servlet?

Question

I am creating a pdf using jasper report and I need to pass this pdf from servlet.Can, someone will help me where I made a mistake. This is a piece of code that I use in my application.

ServletOutputStream servletOutputStream = response.getOutputStream();

String fileName="test.pdf";

response.setContentType("application/pdf");
response.setHeader("Content-Disposition","attachment; filename=\"" + fileName + "\"");
response.setHeader("Cache-Control", "no-cache");
try
{
        Map parameters = new HashMap();
        parameters.put("SUBREPORT_DIR", JasperReportFilepath);
        parameters.put("TestId", testID);

        JasperPrint jprint=JasperFillManager.fillReport(filePath, parameters, conn);

        byte[] output=JasperExportManager.exportReportToPdf(jprint);            
        System.out.println("Size====>"+output.length);

        servletOutputStream.write(output);
        servletOutputStream.flush();
        servletOutputStream.close();

        System.out.println("===============>Streaming perfectly");


}
catch(Exception e)
{
        System.out.println("===============>+JasperException"+e.getMessage());
}

and I also could not get the error message. Everything is working fine, but the document is not working. Please help me deal with the problem.

Answer 1

You are better off using:

JasperExportManager.exportReportToPdfStream(jprint, servletOutputStream);

Heh, a late day and a short dollar, but did anyone ask if there is an HTML tag in his tag <OBJECT>?
