我有一个读取 .xlsx 文件并向用户显示内容的应用程序。该应用程序在 Windows 环境下运行良好。
我在 ubuntu 服务器上的 tomcat6 上部署了这个 Web 应用程序的 .war 文件。我还复制了服务器上的 .xlsx 文件。
代码中文件的路径是正确的。
但是线
FileInputStream file = new FileInputStream(new File(FileName));
XSSFWorkbook workbook = new XSSFWorkbook(file);
给出错误
java.lang.reflect.InvocationTargetException
org.apache.poi.POIXMLException: java.lang.reflect.InvocationTargetException
org.apache.poi.xssf.usermodel.XSSFFactory.createDocumentPart(XSSFFactory.java:62)
org.apache.poi.POIXMLDocumentPart.read(POIXMLDocumentPart.java:403)
org.apache.poi.POIXMLDocument.load(POIXMLDocument.java:155)
org.apache.poi.xssf.usermodel.XSSFWorkbook.<init>(XSSFWorkbook.java:207)
com.qm.action.GetProjectNames.execute(GetProjectNames.java:107)
我已检查变量 FileName 是否包含服务器上文件的正确路径和文件名（/usr/local/Metrics/MetricFiles/FY2013_Q2_GIT_Review_Metrics_by_LSS-GC.xlsx）
由于 ubunut 服务器是一个虚拟机，我使用 WinSCP 复制了 .xlsx 文件。文件的大小也是正确的。
为什么linux平台会出现这个错误？
添加附加异常跟踪
