And this is my code

private void readMSDocuments(String fileToRead) {

    boolean containsEditorAndMt = false;
    String fileEditorAndMt = null;
    dataArray = null;
    try {

        fis = new FileInputStream(new File(fileToRead).getAbsolutePath());
        fs = new POIFSFileSystem(fis);
        document = new HWPFDocument(fs);
        wordExtractor = new WordExtractor(document);
        dataList = new ArrayList();
        dataArray = wordExtractor.getParagraphText();//getParagraphText() reads paragraphs so problem is each paragraph is read a single line .u can see in console
        System.out.println(dataArray.length);
        if (dataArray.length >= 0) {


            for (int k = 0; k < dataArray.length; ++k) {

                if (dataArray[k].trim().length() > 0) {

                    dataList.add(dataArray[k].trim());
                    //System.out.println(fileToRead+" "+dataArray[k].trim()+"\n");
                }
            }
        }

    }
}

Could anyone help me find out why the exception is thrown?
