I am trying to figre out how to get a line number as to where I threw an exception from the endTag method. I am trying to use the Locator interface, but I keep getting -1 for the line number. Any help would be apreciated.

Thanks

The default SAX parser implementations in some of the JDKs and XML packs had a "performance optimization" of not counting lines, and it allways returned -1 for the line number. The only solution I know of is to switch to another SAX parser implementation (I think the one in JDK1.4 no longer has this "optimization").

I remember trying it a while ago ...
Here is some code
/** Returns a string of the location. */
private String getLocationString(SAXParseException ex) {
StringBuffer str = new StringBuffer();

str.append("Line[");
str.append(ex.getLineNumber());
str.append("] Column[");
str.append(ex.getColumnNumber());
str.append("]");

return str.toString();

} // getLocationString(SAXParseException)

this page http://java.sun.com/j2ee/1.4/docs/tutorial/doc/JAXPSAX5.html talks about ContentHandler.setDocumentLocator; a callback invoked once before parsing begins. It knows all about the documents location and the parsing position.

i think the addendum tutorials are excellent: http://java.sun.com/j2ee/1.4/docs/tutorial/index.html

Didn't you see Marc allready said he is using a locator? In some SAX implementations, the value returned from the locator for the line number is -1. It doesn't count lines as a performance optimization.

oh. sorry :$
