and this is my java source code. I include this code into a jdeveloper servlet

 

 

JasperReport miReport;

JasperReport otroReport;

JasperPrint jasperPrint;

Map masterParams = new HashMap();

 

 

try {

miReport = JasperCompileManager.compileReport("Y:\Web\webProject\Modelos\servletJasper\public_html\WEB-INF\reports\contenedor.jrxml");

otroReport = JasperCompileManager.compileReport("Y:\Web\webProject\Modelos\servletJasper\public_html\WEB-INF\reports\report1.jrxml");

 

String Prueba="hola";

masterParams.put("PARAM_PRUEBA",Prueba);

 

jasperPrint = JasperFillManager.fillReport(miReport,masterParams,new JREmptyDataSource());

 

byte[] pdfasbytes = JasperExportManager.exportReportToPdf(jasperPrint);

 

ServletOutputStream outstream = response.getOutputStream();

response.setContentType("application/pdf");

response.setContentLength(pdfasbytes.length);

 

response.setHeader("Content-disposition",

"inline; filename="Report.pdf"");

outstream.write(pdfasbytes);

 

JasperExportManager.exportReportToPdfFile(jasperPrint, "Y:\Web\webProject\Modelos\servletJasper\public_html\WEB-INF\reports\simple_report.pdf");

 

} catch (JRException e) {

e.printStackTrace();

}

 

}

 

Some idea: I reades the tutorial, the examples and It's simple...but i can't send a parameter to my master report. One more thing: I saw the pdf file into the web browser but don't send the parameters
