Before I am using jasperreports-3.7.4 jar for downloading Jasper Reports in the form of Excel Format. Now I am trying to upgrade to jasperreports-6.3.1 jar. But it showing Error like "java.lang.NoSuchMethodError: org.apache.poi.hssf.usermodel.HSSFWorkbook.getCreationHelper()Lorg/apache/poi/hssf/usermodel/HSSFCreationHelper;" while calling exporterXLS.exportReport() method. I am using poi-3.6 jar also. Please provide solution to resolve this problem. Please find my code bellow.
handleDataBase db=null;
try {
OutputStream OutputStream = res.getOutputStream();
db = new handleDataBase();
Utility.comment("attra","before loading the Report "+new java.util.Date() + " - file name is "+reportFileName);
Connection connObj = db.getConnection();
//String jrPrint =JasperFillManager.fillReportToFile(jrxmlFile,params,connObj);
JasperPrint jasperPrint = JasperFillManager.fillReport(jrxmlFile, params, connObj);
Utility.comment("attra","After loading the Report "+new java.util.Date()+ " - file name is "+reportFileName);
