XML "Document root element is missing"

Question

i have made a research in the forums but i have no definite solution about the error.
my flash client sends XML stream to my ServerSocket. and i want to parse these XML datas.
Document XMLDoc;
DocumentBuilderFactory Factory = DocumentBuilderFactory.newInstance();
DocumentBuilder Builder = Factory.newDocumentBuilder() ;
InputSource Is = new InputSource(new BufferedReader(new InputStreamReader(Sock.getInputStream(),"UTF-16LE")));
XMLDoc = Builder.parse(Is);
But now i have problem called "Document root element is missing". My XML stream comming from flash client :
// Actionscript code :
     XDoc = new XML("<?XML version=\"1\"?><LOGIN><USERNAME>KHARON</USERNAME><PASSWORD>485009</PASSWORD></LOGIN>");
----- The XML data i want to sent to ...
<?XML version="1"?>
<LOGIN>
<USERNAME>KHARON</USERNAME>
<PASSWORD>485009</PASSWORD>
</LOGIN>
What is the problem ?

Answer 1

now ?
// Actionscript
XSock = new XMLSocket();
XSock.connect("127.0.0.1",6667);
XDoc = new XML("<?xml version=\"1.0\"?><LOGIN><USERNAME>KHARON</USERNAME><PASSWORD>ew2345dfs</PASSWORD></LOGIN>");
// Java
public void run() {
try {
Document XMLDoc;
DocumentBuilderFactory Factory = DocumentBuilderFactory.newInstance();
DocumentBuilder Builder = Factory.newDocumentBuilder() ;
InputSource Is = new InputSource(new BufferedReader(new InputStreamReader(Sock.getInputStream(),"UTF-16LE")));
XMLDoc = Builder.parse(Is);
org.w3c.dom.Node Node = XMLDoc.getFirstChild();
System.out.print(Node.getNodeValue());
/* Incomming data test code
System.out.print("Listening to incomming messeges");
char in ;
while ( (in = (char)Reader.read()) != -1 ) {
System.out.print( in );
but the result
parser exception ( Document root element is missing )
ihave made a research ( i am newbee in XML) and i have made some declerations like <!DOCTYPE LOGIN <!Element ...
i have declared root element with DOC type decleration. but the same error. :|
since 2 days i am working over these, but solution = null
