Answer 1

For those who are using JRCsvExporter, the following code may be useful. Giving some sample structure.

Spring Framework Service class (CSVExportService.java):

public JasperPrint getRawData(String empIds) {

JasperPrint jp = null;
String reportName = "Employee Report";

// use your own method to get empList
// eg: List<Employee> empList = empServiceClass.findByEmpIds(empIds);
JRDataSource jrDataSource = new JRBeanCollectionDataSource(empList);

// build your report 
DynamicReportBuilder dynamicReportBuilder = new DynamicReportBuilder();
dynamicReportBuilder.setAllowDetailSplit(false);
// configure your report with few more options here

// create columns
ColumnBuilder columnBuilderName = ColumnBuilder.getNew();
columnBuilderName.setTitle("Emp Name");
columnBuilderName.setWidth(300);
columnBuilderName.setFixedWidth(true);
columnBuilderName.setColumnProperty("name", String.class.getName());
dynamicReportBuilder.addColumn(columnBuilderName.build());

DynamicReport dynamicReport = dynamicReportBuilder.build();

jp = DynamicJasperHelper.generateJasperPrint(dynamicReport, new ClassicLayoutManager(), jrDataSource, new HashMap<String, Object>());
return jp;
}

Spring Framework Controller Class:

public void exportToCSV(@PathVariable String empIds){
  JasperPrint jp = null;
  jp = csvExportService.getRawData(empIds);
  response.setContentType("text/csv");
  response.setHeader("Content-Disposition", "attachment; filename="EMPRawData.csv");
  OutputStream out = response.getOutputStream();
  JRCsvExporter exporterCSV = new JRCsvExporter();
  exporterCSV.setParameter(JRExporterParameter.JASPER_PRINT, jp);
  exporterCSV.setParameter(JRExporterParameter.OUTPUT_STREAM, out);
  exporterCSV.exportReport();

  out.flush();
}

Use as a JRXlsExporter to export to XSL and a JRCsvExporter for CSV.

There should be no need to create a custom class in most cases.

Edit

The class is stored inside the jar poi-3.5-FINAL-20090928.jar, which should be locate in your "iReportInstallationFolder"\modules\ext\

For me it's C:\Program Files\Jaspersoft\iReport-3.7.4\ireport\modules\ext\

The name could be different but should be poi-3.5-FINAL-*.jar.

Make it is included in your classpath and you should be fine.

You can download the jar from Apache Poi home page.

Here is a link to the jar I have from their site http://archive.apache.org/dist/poi/release/bin/poi-bin-3.5-FINAL-20090928.tar.gz

    JRCsvExporter exporter = new JRCsvExporter();
    exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
    exporter.setExporterOutput(new SimpleWriterExporterOutput(new FileOutputStream(new File(output1))));
    SimpleCsvExporterConfiguration configuration = new SimpleCsvExporterConfiguration();
    //configuration.setWriteBOM(Boolean.TRUE);
    exporter.setConfiguration(configuration);
    exporter.exportReport();

Kindly use this code .its working fine
