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
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。
