I had exactly the same problem, with JDK 1.4 beta 2 and Tomcat. I used a 
very dirty hack to solve it. I didn't understand the problem (have tried 
quite a lot of options) and had to use Xerces for XML Schema support.

import org.jdom.input.SAXBuilder;
import org.apache.xerces.parsers.SAXParser;
import org.xml.sax.XMLReader;

public class XercesBuilder extends SAXBuilder
	public XercesBuilder(boolean validating)

	protected XMLReader createParser() throws Exception
		return new SAXParser();

Hope anyone can find out what's going, it's really very obscure.
