Hello, I'm having an issue exporting from an iReport to an Excel format. I have seen other threads regarding this topic, but I did not find the offered solutions very helpful. I'm using JRXlsExporter as seen here: JRXlsExporter exporterXLS = new JRXlsExporter(); exporterXLS.setParameter(JRXlsExporterParameter.JASPER_PRINT, print); exporterXLS.setParameter(JRXlsExporterParameter.OUTPUT_STREAM, output); exporterXLS.exportReport(); But this error occurs during exportReport(): java.lang.NoSuchMethodError: org.apache.poi.hssf.usermodel.HSSFSheet.setColumnWidth(II)V I have tried updating my jasperreports jar (which has been the general wisdom to fix this) to both poi-3.1-FINAL.jar and poi-3.5-beta1.jar, but neither have corrected the problem. setColumnWidth is depreciated, but where might I turn to find a jar or resource that has addressed this issue? I'd appreciate any comments or help. Curt
