White spaces are required between publicId and systemId

Question

Hello,
I'm new to Java/XML and have been searching the XML forums for a viable answer trying to get around this error
"White spaces are required between publicId and systemId"
I'm a little unsure of this, however my understanding of this error is that "whitespace" must exist between my "tag entities". So I have modified my XML document to include white space between entities...below is a snippet of my XML doc
// Begin snippet...
<auth>
<userid>
12345
</userid>
<first>
first value
</first>
<second>
</second>
</auth>
//End snippetBelow is the fragment of code I use to set up and parse the XML parse
      SAXParserFactory spf = SAXParserFactory.newInstance();
      //spf.setNamespaceAware(true);
      SAXParser saxParser = spf.newSAXParser();
      XMLReader parser = saxParser.getXMLReader();
      urlConnection = url.openConnection();
      in = urlConnection.getInputStream();
      ins = new InputSource( in );
      // create a handler
      Handler handler = new Handler();
      handler.setBVSessionData( bvdata );
      // assign the handler to the parser
      parser.setContentHandler(handler);
      parser.parse( ins ); // SAXException is thrown here...what gives??
//...In addition, I'm able to read the XML file fine if I point the URL to the XML file locally on my PC, however when the XML doc is served by a web server over HTTP, then read by my app, the SAXException is thrown. Any insight or examples is greatly appreciated. Thanks in advance.

Answer 1

In case anybody is interested here is what I've been able to find...thanks to a little helpful book "XML and Java 2nd Edition" [Maruyama, Tamra, Uramoto, Murata, Clark]
Since I'm using a SAX parser the example doesn't really help. However the book references a DOM parser and uses a "getIsIgnorableWhitespace()" method which as my luck may have it is not available in SAX...
The book goes on to state there are two ways to tell an XML processor or an application if certain whitespace is significant:
1) "Define the significant whitespace in the content models in the DTD"
2) "Specify the xml:space="preserve" attribute in an XML document in order to indicate the intent that applications preservce all whitespace"
Can anybody elaborate on the above, especially #1 or even provide an example that would work with SAX. Thanks...
