爲什麼我得到這個，org.xml.sax.SAXParseException，異常？

我在OpenBravoPOS v2.30的工作，任何人都知道嗎？這是一個有免費許可證的POS機。我試圖改進它，但在我的一臺測試計算機中，它失敗了。最重要的是，我讀了關於類似的情況在stackoverflow，但他們是無奈的。爲什麼我得到這個，org.xml.sax.SAXParseException，異常？

下面是完整的異常輸出：

它指出在該行的代碼：

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); 

    }

爲什麼它拋出我的異常？這是XML文件的問題？它應該是在不同計算機上的相同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碼，不知道該如何解釋更好

什麼是'ticketline'？ stacktrace告訴你它遇到了「文件過早結束」，所以我會看看XML，因爲它可能不是格式良好的。 – andyb 2013-05-09 08:02:46

由於聲明爲靜態，可能會導致SAXParser問題？這是什麼代碼？ – Kuchi 2013-05-09 08:04:02

我會修改我的問題以顯示XML – DavidM 2013-05-09 08:04:08

我OpenBravoPOS工作太，我認爲你錯誤地認爲這是你得到錯誤的XML。

看Ticket.LineRefund不在Ticket.Line看看你是否有錯誤。

對不起，如果我太晚了。

爲什麼我得到這個，org.xml.sax.SAXParseException，異常？
