创建Apache POI实例时，代码停止工作，没有任何错误

Question

我正在使用ApachePOI读取Excel文件，它在本地机器（独立程序）中运行良好，但在服务器（IBMWebSphere）中未运行。当遇到实例化工作簿时，它停止工作。

下面的罐子被使用。

commons-codec-1.5.jarpoi-3.9.jarpoi-examples-3.9.jarpoi-ooxml-3.9.jarpoi-ooxml-schemas-3.9.jarxmlbeans-2.6.0.jar

下面是我的代码：

    String mountInFilePath = "//XXXXX/YY/Foooo/folder/";
    File fileList = new File(mountInFilePath);
    File[] fileNames = fileList.listFiles();
    String inFileName = null;

    if(fileNames != null && fileNames.length > 1){
        throw new Exception("Multiple Files found in "+mountInFilePath+", Please place the latest one.");
    }else{
        System.out.println("getAbsolutePath: "+fileList.getAbsolutePath());
        for(File file : fileNames){
            System.out.println("New file path: "+file.getCanonicalPath());
            inFileName = file.getCanonicalPath();
        }
    }
    LOGGER.info("File: "+inFileName);
    if(inFileName != null){
        LOGGER.info("Inside IF cond...");
        System.out.println("Inside IF cond...");

        //Getting the workbook file
        LOGGER.info("After FileInputStream...");

        File chkAcc = new File(inFileName);
        if(chkAcc.canRead()){
            LOGGER.info("File Readable..");    //This is printed
        }else{
            LOGGER.info("Can not read file..");
        }
        Workbook workbook = WorkbookFactory.create(chkAcc);  //Stopped here
        //Iterating work sheet
        LOGGER.info("Iterating...");
        System.out.println("Iterating...");

一旦检查这些依赖项jar是否实际包含在最终构建中（您部署在服务器中的构建）。我在Weblogic服务器中遇到了这种问题，在构建.ear文件时，我没有包括jar
