实例化对象NPOIFSFileSystem使用文件的问题 [英] Issues instantiating NPOIFSFileSystem Object with File
问题描述
首先登场的我问从家里这个问题= - 远离所有的来源;我会尝试更新的明天。
First up I am asking this question from home =- away from all the source; I will attempt to update tomorrow.
从本质上讲，我实例化NPOIFSFileSystem像这样：
Essentially I am instantiating NPOIFSFileSystem like so:
NPOIFSFileSystem fs = new NPOIFSFileSystem(new File(this.getLocalFile()));
该getLocalFile（）方法返回一个字符串文件路径 - 我知道文件在该位置存在。然而，instatiation返回错误：
The getLocalFile() method returns a String to a file path - I know the file exists in that location. However, the instatiation is returning an error:
ArrayIndexOutOfBounds
有没有人有任何想法在这呢？
Does anyone have any ideas on this at all?
问题中的文件是一个XLS文件，它不包含阿拉伯语字符，我不知道这是否会导致问题。
The file in question is an XLS file, it does contain Arabic characters and I wonder if that could cause the problem.
我没previously有这个使用POIFSFileSystem，但有问题的XLS文件引起了一些问题和各种论坛建议迁移到NPOIFSFileSystem
I did previously have this using POIFSFileSystem but the XLS file in question caused some issues and various forums recommended moving to NPOIFSFileSystem
那么，有没有人见过这个？或者，任何人都可以给我提供一些这方面的提示/指针吗？
So, has anyone seen this before? Or can anyone offer me some tips/pointers on this please?
如果只是问及明天，当我回来工作（我们有固定我们的互联网连接），我会更新这个问题，需要进一步明晰
If any further clarity is needed just ask and tomorrow, when I'm back at work (and we have fixed our internet connection) I will update this question.
在此先感谢

Thanks in advance Nathan

我正在POI3-8
I am running POI3-8
我会升级到3.9，然后再试一次，让你知道。
I will upgrade to 3.9 and try again and let you know.
谢谢

我已经更新到3.9，并很快将再次测试 - 只是在等待其他一些项目在测试之前完成。我会回来后的结果。
I have updated to 3.9 and will test again soon - just waiting for some other items to complete prior to testing. I will post back the results.
谢谢

同样奇怪的问题。这里是堆栈跟踪现在，我使用POI 3.9：
EDIT 3 Same odd problem. Here is the stack trace now I'm using POI 3.9:

修改4
我从NPOIFSFileSystem切换到POIFSFileSystem：
EDIT 4 I have switched from NPOIFSFileSystem to POIFSFileSystem:
FileInputStream fis = new FileInputStream(this.getFileToParse());
POIFSFileSystem excelFile = new POIFSFileSystem(fis);
Workbook wb = WorkbookFactory.create(excelFile);
这给我下面的堆栈跟踪：
This give me the following stack trace:

我知道文件的存在，并且是一个有效的XLS文件。
I know the file exists and is a valid XLS file.
我使用Java 1.7和POI 3.9。
I am using Java 1.7 and Poi 3.9.
该应用程序是从/ usr / JAVA / data_map_tool运行，文件下载，并从加工的/ home / javaapp / data_map_files
The application is running from /usr/java/data_map_tool and the files are downloaded to and processed from /home/javaapp/data_map_files
应用程序谁是有问题的目录的所有者javaapp用户下运行。
The application runs under the javaapp user who is the owner of the directories in question.
在一个点上，我有应用程序运行在目录中下载到一个目录中的文件和工作 - 但是，文件大小禁止要去使用，作为一个文件存储
At one point I had the files downloaded to a directory within the directory the application is running under and that worked - however, the file size prohibits on going use of that as a the file store.
有没有人有任何想法在这，因为我撞我的头靠在墙上与此有关。
Does anyone have any ideas on this as I am banging my head against the wall with this.
推荐答案
好了，我已经破解了！如所建议的问题是与原始源文件。为了削减长话短说是BOM。有一个字节顺序标记的XSL文件的开始。当我的Java应用程序打开这种带有一个FileInputStream它会导致混乱。
Well, I've cracked it! As suggested the issue was with the original source file. To cut a long story short it was BOM. There was a Byte Order Marker at the start of the XSL file. When my Java application opens this with a FileInputStream it causes chaos.
所以，我刚刚更新了我的code来打开文件
So, I just updated my code to open the file with
BOMInputStream();
来自Apache公地IO。
from Apache commons io.
这已经解决了这个问题。
This has resolved the issue.
非常感谢
