为什么我得到这个，org.xml.sax.SAXParseException异常？

标签： java xml saxparser openbravo

我在OpenBravoPOS v2.30工作，有人都知道吗？这是一个拥有免费许可证的POS。 我正在努力改进它，但是在我的一台测试计算机中，它失败了。

最重要的是，我在stackoverflow中读过类似的案例，但是他们很无奈。

这是完整的异常输出：

它指向那行代码：

private static SAXParser m_sp = null;
 public JTicketLines(String ticketline) {

        initComponents();

        ColumnTicket[] acolumns = new ColumnTicket[0];

        if (ticketline != null) {
            try {
                if (m_sp == null) {
                    SAXParserFactory spf = SAXParserFactory.newInstance();
                    m_sp = spf.newSAXParser();
                }
                ColumnsHandler columnshandler = new ColumnsHandler();
                m_sp.parse(new InputSource(new StringReader(ticketline)), columnshandler);
                acolumns = columnshandler.getColumns();

            } catch (ParserConfigurationException ePC) {
                logger.log(Level.WARNING, LocalRes.getIntString("exception.parserconfig"), ePC);
            } catch (SAXException eSAX) {
                logger.log(Level.WARNING, LocalRes.getIntString("exception.xmlfile"), eSAX);
            } catch (IOException eIO) {
                logger.log(Level.WARNING, LocalRes.getIntString("exception.iofile"), eIO);
            }
        }

        initColumns(acolumns);

    }

为什么它会抛出那个例外？这是XML文件的问题？它应该是不同计算机上的相同XML。

LoadTicketLines：

protected void loadTicketLines(DataLogicSystem dlSystem) {
        ticketlines = new JTicketLines(dlSystem.getResourceAsXML("Ticket.Line"));
    }

XML文件：

<?xml version="1.0" encoding="UTF-8"?>

很抱歉，如果它包含大量代码，不知道如何更好地解释

1 个答案:

答案 0 :(得分：2)

我也在OpenBravoPOS工作，我认为你认为这是你得到错误的XML是错误的。

查看Ticket.LineRefund而不是Ticket.Line，看看你是否有错误。

对不起，如果我来不及。
