I have a method below. It was running fine before. Why suddenly
the following line of code throws me a Throwable with null
message?
dbf.setIgnoringElementContentWhitespace(true);
in the "catch (Throwable t)" block, it prints: Throwable caught
in toXML(): null
public static Document toXML()
{
Document doc = null;
try
{
DocumentBuilderFactory dbf =
DocumentBuilderFactory.newInstance();
dbf.setIgnoringComments(true);
dbf.setValidating(false);
dbf.setIgnoringElementContentWhitespace(true);
dbf.setCoalescing(true);
dbf.setExpandEntityReferences(true);
DocumentBuilder docBuilder = null;
try
{
docBuilder = dbf.newDocumentBuilder();
}
catch (ParserConfigurationException pe)
{
System.out.println("ParserConfigurationException
caught in toXML(): " + pe.getMessage());
}
docBuilder.setErrorHandler(new DefaultHandler());
doc = docBuilder.parse(new
File(EVENT_TEMPLATE_XML_FILE));
// normalize text representation
doc.getDocumentElement().normalize();
} catch (SAXParseException err)
{
System.out.println("SAXParseException caught in
toXML(): " + err.getMessage());
} catch (SAXException e)
{
System.out.println("SAXException caught in toXML():
" + e.getMessage());
} catch (Exception ne)
{
System.out.println("Exception caught in toXML(): " +
ne.getMessage());
} catch (Throwable t)
{
System.out.println("Throwable caught in toXML(): " +
t.getMessage());
}
return doc;
}// end toXML()
