Can someone help me with a problem of parsing an XML file?

Question

Hello,
I'm having some problems parsing an xml file. I get a SAXNotSupportedException when setting a property value.
Here is the piece of code where I have the problem:
SAXParserFactory spf = SAXParserFactory.newInstance();
spf.setNamespaceAware(true);
SAXParser saxParser = spf.newSAXParser();
XMLReader xmlReader = saxParser.getXMLReader();
DefaultHandler defHandler = new DefaultHandler();
xmlReader.setProperty("http://xml.org/sax/properties/lexical-handler", defHandler);
and the log is:
Problem with the parser org.xml.sax.SAXNotSupportedException: PAR012 For propertyID "http://xml.org/sax/properties/lexical-handler", the value "org.xml.sax.helpers.DefaultHandler@4ff4f74a" cannot be cast to LexicalHandler.
http://xml.org/sax/properties/lexical-handler org.xml.sax.helpers.DefaultHandler@4ff4f74a LexicalHandler
I've been working on this problem but I can't find the error.
Does anyone have an idea of what to do to solve it?
Thanx in advance,
M@G

Answer 1

before deciding which XML technology to use, you should see if your application fit in the category below:
use SAX:
1. The XML file is rather large (30 or 40+ MB)
2. I don't need the xml document in memory. I will parse the document and store the data in my own object.
use DOM or JDOM
1. The XML file is relatively small (less than 30 MB) or I can increase the runtime memory for larger xml file.
2. I will need to walk up and down the xml document tree severals time.
3. My application is in Java and it's not going to be rewritten in C++, etc (use JDOM)
NOTE:
JDOM is rather easier to use (for Java developer), but it's not an www.org.com standardlized xml parser.
personally, i like JDOM for traversing the DOM.
