poi3.8导出excel new XSSFWorkbook(); 时有问题

Question

private void produceExcel(String sheetName,String[]titles,List resultList
   ,String[]mapKeys,String[]mapKeyTypes,String excelName,String QDFalg
   ,String txtSt,String city) throws IOException {
   try {
         Workbook wb = new  XSSFWorkbook();
    Sheet sheet = createSheet(wb,sheetName);//创建表单
          buileHeadLine(sheet,titles,wb);//创建首行标题   
          buildCell(sheet,resultList,wb,mapKeys,mapKeyTypes);//根据数据List创建内容单元格

 

运行到Workbook wb = new  XSSFWorkbook行是debug进去没报任何错

进到了MultiActionController.class

 

用了以下几个包 
   poi-3.8-beta5-20111217.jar
   poi-ooxml-3.8-beta5-20111217.jar
   xmlbeans-2.3.0.jar
   poi-ooxml-schemas-3.8-beta5-20111217.jar
   dom4j-1.6.1.jar
