Description

When creating a Transformer from TransformerFactory.newInstance() by passing a
StreamSource of XSLT, a TransformerException is thrown, but does not include any
location information.

By exploring the TransformerException using this bit of code, I saw there was a
SAXParseException that contained location information:

boolean known = true;
while (known && (t != null)) {
if (t instanceof TransformerException)

{ known = true; log4j.debug("Analysing known exception: " + t.getClass().getName()); log4j.debug("getLocationAsString(): " + ((TransformerException) t).getLocationAsString() + ""); t = ((TransformerException) t).getCause(); }

else if (t instanceof org.xml.sax.SAXParseException)

{ known = true; log4j.debug("Analysing known exception: " + t.getClass().getName()); int col = ((org.xml.sax.SAXParseException) t).getColumnNumber(); int line = ((org.xml.sax.SAXParseException) t).getLineNumber(); log4j.debug("Location: Col=" + col + ", line=" + line); t = ((org.xml.sax.SAXParseException) t).getException(); }

else

{ log4j.debug("Unknown cause: " + t.getClass().getName()); known = false; }

}

Note: If you don't use log4j, replace "log4j.debug" by "System.out.println", for
example.

The result of this exploration gives:

Analysing known exception: javax.xml.transform.TransformerConfigurationException
getLocationAsString(): null
Analysing known exception: javax.xml.transform.TransformerConfigurationException
getLocationAsString(): null
Analysing known exception: javax.xml.transform.TransformerException
getLocationAsString(): null
Analysing known exception: org.xml.sax.SAXParseException
