使用Selenium Webdriver读取和写入excel文件时出现意外错误

excel junit selenium-webdriver

使用Selenium Webdriver读取和写入excel文件时出现意外错误,excel,junit,selenium-webdriver,Excel,Junit,Selenium Webdriver,我用这种方法来阅读 FileInputStream fi = new FileInputStream("C:\\Users\\GChaitanya.CHAINGANG\\Desktop\\2012_October_3PL_Unified_Template.xls"); Workbook w = Workbook.getWorkbook(fi); s = w.getSheet(0); 这是要写的吗 WritableWorkbook wb = Workbook.createWorkbook(new

我用这种方法来阅读

FileInputStream fi = new FileInputStream("C:\\Users\\GChaitanya.CHAINGANG\\Desktop\\2012_October_3PL_Unified_Template.xls");
Workbook w = Workbook.getWorkbook(fi);
s = w.getSheet(0);

这是要写的吗

WritableWorkbook wb = Workbook.createWorkbook(new File("D:\\output_2.xls"));
WritableSheet ws = wb.createSheet("customsheet", 1);

我得到这个错误
