[anupp]

Code:

Hi All,

      i want to generate pdf file directly.when click the save button then directly pdf file should be generated.Actually i have generated pdf file through jasper but i have mentioned destination so its not required.My Requirement is after clicking the save button then pdf should be generated.



    HttpServletRequest request = (HttpServletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest();

    String reportPath =

    request.getSession().getServletContext().getResource("/reports").toString().substring(6); // substring cuts off the 'file://'

    File file = new File(reportPath + "TransferSecretaries_Report.jasper");

    String file1 = file.toString();

 String dest = "c:/transferSecreatary.pdf";



    jasperPrint =JasperFillManager.fillReport(file1, new HashMap(),simpleDS);

    //generates PDF

    JasperExportManager.exportReportToPdfFile(jasperPrint, dest);

   

    }

Make sure you have the Headers set correctly. For example, in PHP you would do:

header('Cache-Control: private');
header('Content-Description: File Transfer');
header("Content-Disposition: attachment, filename=$filename.pdf");
header('Content-Type: application/pdf');
header('Content-Transfer-Encoding: binary');
header('Content-Length: ' . strlen( $result ) );

In Java, you have to use the HttpServletResponse, I believe, and I don't know if it automatically sets the content-length for you.

Also, the Cache-Control makes sure that IE does not cache the results of the PDF each time -- otherwise you can't get a new PDF!
