我在工作OpenBravoPOS v2.30，有人知道吗？这是一个免费许可的 POS。我正在尝试改进它，但在我的一台测试计算机中，它失败了。
毕竟，我在 stackoverflow 中读到过类似的案例，但他们都束手无策。
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);
}
为什么它会抛出这个异常？这是XML文件的问题吗？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"));
}
和 XML 文件：
<?xml version="1.0" encoding="UTF-8"?>

对不起，如果它包含很多代码，不知道如何更好地解释它
