strange error while working with JasperReports, Hibernate and Spring

Question

I am getting a strange error when trying to print my report.

Handler processing failed; nested exception is java.lang.VerifyError: class org.codehaus.groovy.runtime.callsite.GroovySunClassLoader$2 overrides final method visit.(IILjava/lang/String;Ljava/lang/String;Ljava/lang/String;[Ljava/lang/String;)V

Please can anyone suggest what can be the solution for this.

here is the code for printing the jasper report.

@RequestMapping("/report")
    public String displayReport(Map<String,Object> map){

        System.out.println("Hello");
        String sourceFileName = "D://jasper"
                + "/report2.jrxml";
        String jasperFileName = "D://jasper"
                + "/report2.jasper";

        List<Project> projectList=projectService.getAllproject();
        String printFileName = null;
        JRBeanCollectionDataSource beanColDataSource =
                new JRBeanCollectionDataSource(projectList);

        try{

            // 1. Add report parameters
            HashMap<String, Object> parameters= new HashMap<String, Object>(); 

            parameters.put("ReportTitle", "Project Details");
            parameters.put("Author", "Prepared By Priyanka");

            JasperCompileManager.compileReportToFile(sourceFileName);
            printFileName = JasperFillManager.fillReportToFile(jasperFileName,
                    parameters, beanColDataSource);
            if (printFileName != null) {
                /**
                 * 1- export to PDF
                 */
                JasperExportManager.exportReportToPdfFile(printFileName,
                        "D://jasper/sample_report.pdf");

                /**
                 * 2- export to HTML
                 */
                JasperExportManager.exportReportToHtmlFile(printFileName,
                        "D://jasper/sample_report.html");

                /**
                 * 3- export to Excel sheet
                 */
                JRXlsExporter exporter = new JRXlsExporter();

                exporter.setParameter(JRExporterParameter.INPUT_FILE_NAME,
                        printFileName);
                exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME,
                        "D://jasper/sample_report.xls");

                exporter.exportReport();
            }
        } catch (JRException e) {
            e.printStackTrace();
        }


        return "report"; 


    }

also the stack trace is as follows:

Answer 1

The language attribute in the header of your report2.jrxml file is set to groovy, not java.

<jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" 
... 
language="groovy" 
...>

Change this to

<jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" 
... 
language="java" 
...>
