Question

以下代码可将.doc文件转换为HTML文件。但它似乎只适用于包含“普通”文本的doc文件。在尝试将包含text-properties的.doc转换为 Bold 并加下划线时，它会向我显示错误消息。如何解决这个问题？

`public class ConvertDoc {

public void createHTML() throws Exception {

try {


        File sdcard = Environment.getExternalStorageDirectory();
        File file = new File(sdcard, "/MyFolder/myfile.doc");

        HWPFDocumentCore document = WordToHtmlUtils.loadDoc(new FileInputStream(file));

        WordToHtmlConverter wordToHtmlConverter = new WordToHtmlConverter(DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument());
        wordToHtmlConverter.processDocument(document);

        Document htmlDocument = wordToHtmlConverter.getDocument();

        ByteArrayOutputStream out = new ByteArrayOutputStream();
        DOMSource domSource = new DOMSource(htmlDocument);
        StreamResult streamResult = new StreamResult(out);

        TransformerFactory tf = TransformerFactory.newInstance();
        Transformer serializer = tf.newTransformer();
        serializer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
        serializer.setOutputProperty(OutputKeys.INDENT, "yes");
        serializer.setOutputProperty(OutputKeys.METHOD, "html");
        serializer.transform(domSource, streamResult);
        out.close();

        String html = new String(out.toByteArray());


        BufferedWriter outstream = new BufferedWriter
                (new OutputStreamWriter(new FileOutputStream(sdcard + "/MyFolder/myfile.html"), "UTF-8"));

        outstream.write(html);
        outstream.close();



    } catch (Throwable e) {
        e.printStackTrace();
    }try`

Answer 1

propertySetFactory中基于RMI的异常会生成此错误。

正如http://poi.apache.org/changes.html链接所提到的那样，“避免使用PropertySetFactory中的基于RMI的异常，因为它不需要也没有帮助”已在版本3.10-FINAL（2014-02-08）中修复。

使用，3.10最终版或高版本摆脱'java.rmi.UnexpectedException'错误。
