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

我在OpenBravoPOS v2.30的工作，任何人都知道吗？这是一个有免费许可证的POS机。我试图改进它，但在我的一台测试计算机中，它失败了。最重要的是，我读了关于类似的情况在stackoverflow，但他们是无奈的。为什么我得到这个，org.xml.sax.SAXParseException，异常？

下面是完整的异常输出：

它指出在该行的代码：

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); 

    }

为什么它抛出我的异常？这是XML文件的问题？它应该是在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：

很抱歉，如果它包含了大量的代码，不知道该如何解释更好

什么是'ticketline'？ stacktrace告诉你它遇到了“文件过早结束”，所以我会看看XML，因为它可能不是格式良好的。 – andyb 2013-05-09 08:02:46

由于声明为静态，可能会导致SAXParser问题？这是什么代码？ – Kuchi 2013-05-09 08:04:02

我会修改我的问题以显示XML – DavidM 2013-05-09 08:04:08

我OpenBravoPOS工作太，我认为你错误地认为这是你得到错误的XML。

看Ticket.LineRefund不在Ticket.Line看看你是否有错误。

对不起，如果我太晚了。
