Help: schema validation : NoSuchMethodError: org.w3c.dom.Document: method createElementNS

Hi,

I tried to set schema validation like this
class try1 {
   public static void main(String[] args) {
      org.apache.xerces.parsers.DOMParser parser;
      org.w3c.dom.Element ele;
      try {
         parser = new org.apache.xerces.parsers.DOMParser();
         parser.setFeature("http://xml.org/sax/features/validation", true);

parser.setFeature("http://apache.org/xml/features/validation/schema", t
rue);
         parser.parse(args[0]);
         ele = parser.getDocument().getDocumentElement();
      } catch (Exception e) {
         System.out.println(e);
         e.printStackTrace();
      }
   }
}
But I get this exception

Exception in thread "main" java.lang.NoSuchMethodError:

thod

Ian,
I was using jdk 1.2.2 , after seeing a message from Bjoern , I used jdk 1.3
and now it works fine.

SP6

It looks like you have another jar file, other than xerces, in your
classpath which provides the org.w3c.dom interfaces.  If that is DOM level
1 only, then it won't have the namespaced methods xerces uses.  If you
make sure xerces.jar is the first thing in your classpath, everything
should work fine.

Ian
