在上传时，在Workbook wb = isExcel2003 ? new HSSFWorkbook(inputStream) : new XSSFWorkbook(inputStream);这一行抛出 org.apache.poi.openxml4j.exceptions.InvalidOperationException: Can't open the specified file: 'D:\Program Files\Tomcat-6.0\temp\poifiles\poi-ooxml--867705816.tmp'异常。。。。请指点啊。。。在main方法里测试时没有问题。 --------------------编程问答-------------------- 用了这些个jar包。
