DTD and XSD Validation for xml file

Question

hi kindly reply to this mail guru'ssss
i am facing a problem in parising a xml file against dtd and xsd.
i have the dtd which contains only enitities that can be present in the xml file and the xsd file for validation against elements and attribute.
when DTD is present then it is throwing errors like the elements should be declared.
when i take out the doctype line and validate against schema its throwing the error that particular entity is not found or declared.
  public Vector validateSchema(String SchemaUrl, String XmlDocumentUrl)  
      SAXParser parser =new SAXParser();
     try{
         //parser.setNamespaceAware (true);     
         //parser.s
         parser.setFeature("http://xml.org/sax/features/validation",true);
         parser.setFeature("http://apache.org/xml/features/validation/schema",true);
         parser.setFeature("http://apache.org/xml/features/validation/schema-full-checking", true);
        // parser.setProperty("http://xml.org/sax/properties/declaration-handler", new DTDHandl());
         parser.setProperty("http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation",SchemaUrl);
        // parser.setFeature("http://xml.org/sax/features/namespace-prefixes", true);
        // System.out.println(parser.getDTDHandler());
        // UnparsedCache cache = new UnparsedCache();
       //  parser.setDTDHandler(cache);
         InputSource inputSource =new InputSource(new java.io.FileInputStream(new java.io.File(XmlDocumentUrl)));
       //  parser.setDTDHandler(new myDTDHandler());
         //parser.setEntityResolver(new CustomResolver());
     //  parser.setContentHandler(this);
         Validator handler=new Validator();
         parser.setErrorHandler(handler); 
         parser.parse(inputSource);
         if(handler.validationError==true)
           System.out.println("XML Document is not valid");
         else                  
           System.out.println("XML Document is valid");
         for(int i=0;i<ErrorLines.size();i++){
             System.out.println(ErrorLines.elementAt(i));
   }catch(java.io.IOException ioe){  
     System.out.println("IOException"+ioe.getMessage());   
   }catch (SAXParseException e) {
     System.out.println("SAXParseException "+e.getMessage());   
  }catch (SAXException e) {
     System.out.println("SAXException"+e.getMessage());   
     return ErrorLines;
what could be soln to this.

Hi

Based on your description, your case related to XMLＸSD, SO I will move your thread to
