I have created a Jasper Action and jrxml. The following code retrieves data from database, but I am getting a blank report page.
<?xml version="1.0" encoding="UTF-8" ?> <!-- Created with iReport - A designer for JasperReports --> <!DOCTYPE jasperReport PUBLIC "//JasperReports//DTD Report Design//EN" "http://jasperreports.sourceforge.net/dtds/jasperreport.dtd"> <jasperReport name="samplereport" > <field name="number" class="java.lang.Long"/> <field name="english" class="java.lang.String"/> <field name="german" class="java.lang.String"/> <columnHeader> <band height="28" isSplitAllowed="true"> <staticText> <reportElement x="20" y="0" height="20" width="35"/> <text>Month ID:</text> </staticText> <staticText> <reportElement x="220" y="0" height="20" width="65"/> <text>English:</text> </staticText> <staticText> <reportElement x="380" y="0" height="20" width="75"/> <text>German:</text> </staticText> </band> </columnHeader> <detail> <band height="27" isSplitAllowed="true"> <textField> <reportElement x="56" y="0" height="20" width="164"/> <textFieldExpression class="java.lang.Long"> <![CDATA[$F{number}]]> </textFieldExpression> </textField> <textField> <reportElement x="286" y="0" height="20" width="84"/> <textFieldExpression class="java.lang.String"> <![CDATA[$F{english}]]> </textFieldExpression> </textField> <textField> <reportElement x="456" y="0" height="20" width="94"/> <textFieldExpression class="java.lang.String"> <![CDATA[$F{german}]]> </textFieldExpression> </textField> </band> </detail> </jasperReport>

JasperCompileManager.compileReportToFile(contextPath,getServlet().getServletContext().getRealPath("/WEB-INF/classes/jasper/month.jasper")); InputStream reportStream = getServlet().getServletConfig().getServletContext() .getResourceAsStream("/WEB-INF/classes/jasper/month.jasper"); System.out.println("JasperAction,A're reportStreaming"); //QueryResults JRBeanCollectionDataSource beanCollectionDataSource=new JRBeanCollectionDataSource(utilDAO.generateJasperReport(),false); System.out.println("JasperAction,Datsource saved"); //generate report System.out.println("GetRecordCount:"+beanCollectionDataSource.getRecordCount()); JasperFillManager.fillReportToFile(getServlet().getServletContext().getRealPath("/WEB-INF/classes/jasper/month.jasper"), new HashMap(), beanCollectionDataSource); System.out.println("JasperAction,A're fillReportToFile"); //view pdf file in browser window JasperRunManager.runReportToPdfStream(reportStream, servletOutputStream, new HashMap(), connection);

Please help me in this. The beanCollectionDataSource is having all records from the table.But those values are not getting displayed in the pdf. I am getting a blank pdf.
