[jdom-interest] Is BuilderErrorHandler redundant ?

[Koller, Shmuel]

Parsing piece of code:
////////////////////////
private void init(String xmlMessage, boolean validate) throws Exception
    {

        DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
        factory.setValidating(validate);
        try
        {
            DocumentBuilder builder = factory.newDocumentBuilder();
            builder.setErrorHandler(new SAXErrorHandler());
            xmlDocument = builder.parse(new
java.io.ByteArrayInputStream(xmlMessage.getBytes(), 0,
xmlMessage.length()));
        }
        catch(SAXException sxe)
        {
/////////////////////////////////
I inherited above code (except for setErrorHandler) - was told it is SAX
traversal using Xerces underneath JDOM API.

Handler class:
package ...... same as above

import org.jdom.input.BuilderErrorHandler;

import org.xml.sax.SAXException;
import org.xml.sax.SAXParseException;
import for logging


public class SAXErrorHandler  extends BuilderErrorHandler {
      public void warning(SAXParseException spe) throws SAXException {
            Logger.error(this.getClass(),"Warning in " + spe.getSystemId() +
                    " at line " + spe.getLineNumber() +
                    " column= " + spe.getColumnNumber());
    }
    public  void error(SAXParseException spe) throws SAXException {
            Logger.error(this.getClass(),"Error in " + spe.getSystemId() +
                    " at line " + spe.getLineNumber() +
                    " column= " + spe.getColumnNumber());
            throw(spe);
    }
    public  void fatalError(SAXParseException spe) throws SAXException {
            Logger.error(this.getClass(),"FatalError in " +
spe.getSystemId() +
                    " at line " + spe.getLineNumber() +
                    " column= " + spe.getColumnNumber());
            throw(spe);
    }
}

Without sending in your code, it's going to be very hard for anyone to
figure out what's wrong.
