at net.sf.jasperreports.engine.JRAbstractExporter.setInput(JRAbstractExporter.java:858)
at net.sf.jasperreports.engine.export.JRPdfExporter.exportReport(JRPdfExporter.java:259)
at PDFPassword.main(PDFPassword.java:116)

so can you please help me? Please

I am using Eclipse.

I have included all related jars in path
itextpdf-5.2.0.jar,
commons-collections-3.2.1.jar,
commons-beanutils-1.8.2.jar,
commons-javaflow-20060411.jar,
commons-logging-1.1.jar,
jasperreports-4.5.0.jar,
commons-digester-1.7.jar,
groovy-all-1.7.5.jar,
classes12.jar
iText-2.1.7.jar


JasperDesign jasperDesign = JRXmlLoader.load("Path of jrxml file");
JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
Map parameters = new HashMap();
parameters.put("EMPNO", "7369");
Connection conn = DataBase.getConnection();

JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, conn);
JasperExportManager.exportReportToPdfFile(jasperPrint,"Path for PDF file");

JRPdfExporter exporter = new JRPdfExporter();
exporter.setParameter(JRExporterParameter.INPUT_FILE,"Path for PDF file");
exporter.setParameter(JRPdfExporterParameter.IS_ENCRYPTED, Boolean.TRUE);
exporter.setParameter(JRPdfExporterParameter.IS_128_BIT_KEY, Boolean.TRUE);
exporter.setParameter(JRPdfExporterParameter.USER_PASSWORD, "jasper");
exporter.setParameter(JRPdfExporterParameter.OWNER_PASSWORD, "reports");
exporter.setParameter(JRPdfExporterParameter.PERMISSIONS, new Integer(PdfWriter.ALLOW_COPY | PdfWriter.ALLOW_PRINTING));
exporter.exportReport();

PDF file is generated at Specified Location as mentioned in JasperExportManager.exportReportToPdfFile() but it is not password protected,
when code executed exporter.exportReport(); generates this exception. So password is not set to PDF.

Vector is synchronized ArrayList is not
A Vector defaults to doubling the size of its array, while the ArrayList increases its array size by 50 percent.
Apart from this any other difference?
In which situation use ArrayList and in which Vector?
Vector is faster than ArrayList or not?javascript:emoticon
