[HTML report shows images but PDF report is blank]

I think i have the same problem.

Html is perfect (about 3400K), but the pdf file is empty ( 0 bytes).

here is my jsp code.

 

 

 

<%@ page language="java" contentType="text/html;charset=WINDOWS-1252"%>

<%@ page import="java.net.*, java.io.*, java.util.*" ...

...%>

<%

response.setContentType("application/pdf");

response.addHeader("Content-Disposition", "attachment; filename=destinazione.pdf");

 

Hashtable parameterMap = new Hashtable();

int i = 0;

java.sql.Connection myConnection = null;

PreparedStatement myStatement = null;

out.clear();

out.close();

OutputStream outS = response.getOutputStream();

 

try{

JasperDesign jasperDesign = JRXmlLoader.load("C:\Programmi\Apache Group\Tomcat 4.1\webapps\RAPtest2\pdf\reports\provaa.jrxml");

JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);

String myQuery = jasperReport.getQuery().getText();

java.sql.Driver driver = (java.sql.Driver)Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();

Properties properties = new Properties();

properties.put("user", "aa");

properties.put("password", "ss");

myConnection = driver.connect("jdbc:oracle:thin:@121.108.62.130:1521:ORCL", properties);

 

JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameterMap, myConnection);

 

JasperExportManager.exportReportToPdfFile(jasperPrint,"destinazione.pdf");

 

}catch(Throwable ex) {

String connectMsg = "Could not create the report " + ex.getMessage() + " " + ex.getLocalizedMessage();

System.out.println(connectMsg);

System.err.println("nuovo tentativo 3");

System.err.println(connectMsg);

ex.printStackTrace();

}

GlobalConfig.dbpoolfast.returnConnection("fastPR", myConnection);

outS.flush();

%>

 

 

 

 

i've also tried with

 

 

JRExporter exporter = new JRPdfExporter();

exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);

exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, outS);

exporter.exportReport();

 

instead of

 

JasperExportManager.exportReportToPdfFile(jasperPrint,"destinazione.pdf");

but it's the same.

 

any suggestion is appreciate

thanks

bye
