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.

我将此Web应用程序的.war文件部署在ubuntu服务器上的tomcat6上.我还复制了服务器上的.xlsx文件.

代码中文件的路径正确.

但是线

FileInputStream file = new FileInputStream(new File(FileName));

XSSFWorkbook workbook = new XSSFWorkbook(file);

给出一个错误

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.(XSSFWorkbook.java:207)

com.qm.action.GetProjectNames.execute(GetProjectNames.java:107)

我检查了变量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VM,因此我已经使用WinSCP复制了.xlsx文件.文件的大小也正确.

为什么在Linux平台上发生此错误？

添加其他异常跟踪
