xml

[Derek Akers]

I am having a problem parsing an xml file using the following code, trying
to validate the enclosed xml files...

i keep getting the following error:

** Parsing error, line 2, uri null
   Relative URI "Catalog.dtd"; can not be resolved without a document URI.

can anyone help?  sorry for the length...

public boolean checkXML (String source) // source is a file name string
passed from the web
 {
   Document doc;
   String path = "d:/orion/applications/eldan/eldan-web/xml/" + source;

  if (source == null)
   System.out.println("\nValidator:checkXML: source string is null");

   try
   {
     DocumentBuilderFactory docBuilderFactory =
DocumentBuilderFactory.newInstance();
     docBuilderFactory.setValidating(true);
     DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
     Validator v =  new Validator();

     FileInputStream xmlStream = new FileInputStream(path);

//     URL url = v.getClass().getResource(path);
//       doc = docBuilder.parse (url.toString());


     doc = docBuilder.parse(xmlStream);
     valid = true;
     System.out.println("\nxml valid");

     } // end try
   catch (SAXParseException err)
   {
    System.out.println("exception 1");
    System.out.println ("** Parsing error"
    + ", line " + err.getLineNumber ()
    + ", uri " + err.getSystemId ());
   System.out.println("   " + err.getMessage ());
    // print stack trace as below

  } // end catch 1
   catch (SAXException e)
   {
    System.out.println("exception 2");
    Exception x = e.getException ();
       ((x == null) ? e : x).printStackTrace ();
   } // end catch 2
   catch (Throwable t)
  {
    System.out.println("exception 3");
   t.printStackTrace ();
  } // end catch 3
  return valid;
  } // end checkXML
