Why I'm getting this, org.xml.sax.SAXParseException, exception?

Question

I'm working in OpenBravoPOS v2.30, anyone knows about it? It's a POS with free licence. I'm trying to improve it, but in one of my test computers, it fails.

Before all, I'd read about similar cases in stackoverflow, but they were helpless.

Here's the full exception output:

It points at that line of code:

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);

    }

Why it throws me that exception? It's a problem of the XML file? It's supposed to be the same XML at the different computers.

LoadTicketLines :

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

And the XML File:

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

Sorry if it contains a lot of code, dont know how to explain it better

Answer 1

I work in OpenBravoPOS too, and I think you're wrong to think that this is the XML where you get the error.

Look at the Ticket.LineRefund not at Ticket.Line to see if you have the error there.

Sorry if I am too late.
