Validation fails on setAttribute

Hi;
Hi have a small problem and hope you can assist.
I am using the following code fragment taken from sun's XML tutorial, it is
a validating parser creation code:

static final String JAXP_SCHEMA_LANGUAGE =
"http://java.sun.com/xml/jaxp/properties/schemaLanguage
<http://java.sun.com/xml/jaxp/properties/schemaLanguage> ";
static final String W3C_XML_SCHEMA = "http://www.w3.org/2002/XMLSchema
<http://www.w3.org/2002/XMLSchema> ";
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
dbf.setValidating(true);
try{
          dbf.setAttribute(JAXP_SCHEMA_LANGUAGE, W3C_XML_SCHEMA);
}catch(Exception e){
      e.printStackTrace();
}
DocumentBuilder db = dbf.newDocumentBuilder();

With xerces, there is no problem but oracle and weblogic parsers fail in the
setAttribute method.
Is there something wrong here?
Thanks.
