cvc-complex-type.2.1: Element 'property' must have no character or element information item [children], because the type's content type is empty

问题:

I am developing report using jasper report with spring mvc.

I am getting blank page with following error while clicking on view button.

net.sf.jasperreports.engine.JRException: org.xml.sax.SAXParseException; lineNumber: 59; columnNumber: 14; cvc-complex-type.2.1: Element 'property' must have no character or element information item [children], because the type's content type is empty. at net.sf.jasperreports.engine.xml.JRXmlLoader.loadXML(JRXmlLoader.java:247) at net.sf.jasperreports.engine.xml.JRXmlLoader.loadXML(JRXmlLoader.java:230) at net.sf.jasperreports.engine.xml.JRXmlLoader.load(JRXmlLoader.java:218) at net.sf.jasperreports.engine.xml.JRXmlLoader.load(JRXmlLoader.java:172) at net.sf.jasperreports.engine.xml.JRXmlLoader.load(JRXmlLoader.java:156) at net.sf.jasperreports.engine.JasperCompileManager.compile(JasperCompileManager.java:171) at net.sf.jasperreports.engine.JasperCompileManager.compileReport(JasperCompileManager.java:448) at com.asd.cms.service.ReportService.getReport(ReportService.java:137) at com.asd.cms.service.ReportService.generateReport(ReportService.java:58) at com.asd.cms.controller.KGDLCReport.viewReport(KGDLCReport.java:70) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source)

My Code of KGDLCReport.java: com.asd.cms.controller.KGDLCReport.viewReport(KGDLCReport.java:70)

@RequestMapping("/userWiseReportKGDLC")     public void viewReport(HttpServletRequest request, HttpServletResponse response) {     String dateFrom = request.getParameter("dateFrom");     String dateTo = request.getParameter("dateTo");     String outputFormat = request.getParameter("outputFormat");      Map<String,Object> param = new HashMap<String,Object>();     param.put("dateFrom", dateFrom);     param.put("dateTo", dateTo);      String path = request.getSession().getServletContext().getRealPath("/resources/jasper/KGDCL_Report1.jrxml"); **KGDLCReport.java:70** ->  reportService.generateReport(path, outputFormat, param, response); } 

com.asd.cms.service.ReportService.generateReport(ReportService.java:58)

 public void generateReport(String path, String outputFormat, Map<String, Object> param, HttpServletResponse res){     try{         if(new File(path).exists()){              JasperPrint jp = getReport(path, param);  // Line: 58             ByteArrayOutputStream baos = new ByteArrayOutputStream();             //String outputFormat = req.getParameter("outputFormat");             if(outputFormat.equals("pdf")){                  JasperExportManager.exportReportToPdfStream(jp, baos);                     .............          }     }      

com.asd.cms.service.ReportService.getReport(ReportService.java:137)

public JasperPrint getReport(String path, Map<String, Object> parameters) throws SQLException{     JasperPrint print = new JasperPrint();           JasperReport report;     try {          System.out.println("Path inside ReportService.java line 135"+path);           report = JasperCompileManager.compileReport(path); //Line: 137           print = JasperFillManager.fillReport(report, parameters, jdbcTemplate.getDataSource().getConnection());      } catch (JRException e) {            e.printStackTrace();     }     return print; }         

Which one may be the cause of getting error? Thanks in advance.

I have found the problem after doing some R&D. Problem is in report page. Java code is ok. JRXmlLoader can't load xml of the report page accurately. So SAXParser wasn't able to parse xml. That's why I am getting error.
