您的堆栈跟踪，这解释了什么是打破和关键部分原因是：

 产生的原因：java.lang.OutOfMemoryError：Java堆空间
java.util.Arrays.copyOfRange（Arrays.java:2694）
 

这是告诉我们的Java并没有分配给它足够的内存来存储所有的处理文件限嗣继承

数据

如果你需要增加你的JVM堆大小的帮助，我会建议您查看此previous问题或这个，这既谈你经历了这一切。

I have an application which reads an .xlsx file and displays the content to the user. The application works fine on a windows environment.

I deployed the .war file of this web app on tomcat6 on a ubuntu server. I also copied the .xlsx files on the server.

The path of the files in the code is correct.

But the line

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

gives an error

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)

I have checked that the variable FileName contains the correct path and filename of the files on server(/usr/local/Metrics/MetricFiles/FY2013_Q2_GIT_Review_Metrics_by_LSS-GC.xlsx)

Since the ubunut server is a VM, I had copied the .xlsx files using WinSCP. The size of the files is also correct.

Why is this error occurring on linux platform?

Promoting a comment to an answer...

The key part of your stacktrace, which explains what has broken and why, is:

Caused by: java.lang.OutOfMemoryError: Java heap space at 
java.util.Arrays.copyOfRange(Arrays.java:2694)

This is telling us that Java didn't have enough memory allocated to it to store all of the data that processing your file entails

If you need help with increasing your JVM heap size, I would suggest you review this previous question or this one, which both talk you through it all.
