[JSP ] jsp讀取以中名為檔名的xml檔問題

[edward5431 (慶仔)]

如果檔名是以英文來命名就都沒問題,但用中文就會跑出error

        String path = "./WEB-INF/問卷.xml";
        String File = request.getRealPath(path);
        Document BookDom = null;
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

        try{
                DocumentBuilder builder = factory.newDocumentBuilder();
                BookDom = builder.parse(File);

        }catch(Exception e){
                out.print("XML analysis error" + e.getMessage());
        }

        Element element = BookDom.getDocumentElement();

他跑出的exception大致上是以下:
大致就是沒抓到檔案內容的感覺,感謝大大解惑阿~~~
