问题
I have some troubles to export my report as XLS. The export as PDF works well.
So I tried to update to the latest JasperReports and Apache POI version:
- JasperReports: 5.5.0
- POI: 3.7
- iText: 2.1.7
But I receive always following exception:
java.lang.NoSuchMethodError: org.apache.poi.hssf.usermodel.HSSFWorkbook.createDataFormat()Lorg/apache/poi/hssf/usermodel/HSSFDataFormat;
net.sf.jasperreports.engine.export.JRXlsExporter.openWorkbook(JRXlsExporter.java:284)

Export Code
File sourceFile = new File(fileIn);
JasperPrint jasperPrint = (JasperPrint)JRLoader.loadObject(sourceFile);
String name = fileIn.substring(fileIn.lastIndexOf(System.getProperty("file.separator"))+1);
name = name.substring(0, name.lastIndexOf("."));
File destFile = new File(fileOut);
JRXlsExporter exporter = new JRXlsExporter();
exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, destFile.toString());
exporter.exportReport();
After some researches I tried several other Versions(+4) but I still receive this error. Does anyone know a solution?
回答1:
You have an old version library in your class path.
If the jasper report depends on lib-xxx.jar, then make sure that there are no other lib-yyy.jar in your class path. You can do this by reviewing the jasper downloaded jar or pom.xm.
As I can guess there are some old versions of poi in your class path.
