我看到互联网上满是抱怨apache pdf产品的人，但是我在这里找不到我的特殊用例。我正在尝试使用apache poi做一个简单的Hello World。现在，我的代码如下：

public ByteArrayOutputStream export() throws IOException {
    //Blank Document
    XWPFDocument document = new XWPFDocument();

    //Write the Document in file system
    ByteArrayOutputStream out = new ByteArrayOutputStream();;

    //create table
    XWPFTable table = document.createTable();
    XWPFStyles styles = document.createStyles();
    styles.setSpellingLanguage("English");
    //create first row
    XWPFTableRow tableRowOne = table.getRow(0);
    tableRowOne.getCell(0).setText("col one, row one");
    tableRowOne.addNewTableCell().setText("col two, row one");
    tableRowOne.addNewTableCell().setText("col three, row one");

    //create second row
    XWPFTableRow tableRowTwo = table.createRow();
    tableRowTwo.getCell(0).setText("col one, row two");
    tableRowTwo.getCell(1).setText("col two, row two");
    tableRowTwo.getCell(2).setText("col three, row two");

    //create third row …

以下代码不适用于Apache poi 3.16。有人可以提供正确的解决方案吗，在我的项目中，有些人只能使用

public void ConvertToPDF(String docPath, String pdfPath) {
    try {
        InputStream doc = new FileInputStream(new File(docPath));
        XWPFDocument document = new XWPFDocument(doc);
        PdfOptions options = PdfOptions.create();
        OutputStream out = new FileOutputStream(new File(pdfPath));
        PdfConverter.getInstance().convert(document, out, options);
        System.out.println("Done");
    } catch (FileNotFoundException ex) {
        System.out.println(ex.getMessage());
    } catch (IOException ex) {
        System.out.println(ex.getMessage());
    }
}

例外：
