JAXB unmarshall not responding (help needed)

[Buglish]

Hi,
I have mannually generated the java classes used in marshalling.
The package file :
www
.
yourfilelink.com/get.php?fid=464413

(copy from www to 464413)
When running the marhsalling section it stoppes processing when unmarshalling (JAXBElement)without any errors or notifications.

XML to be parsed can be

Code:

<icb_ws>
    <register>
        <userdata>
                <username>n00b</username>
                <password>1234</password>
                <firstname>n00b</firstname>
                <lastname>kiddy</lastname>
                <email>noob( at )yahoo.com</email>
                <country>South Africa</country>
                <mobile>+27820000000</mobile>                
        </userdata>    
    </register>    
</icb_ws>
OR
<icb_ws>
    <login>
        <username>n00b</username>
        <password>n00b</password>
    </login>
</icb_ws>
OR
<icb_ws>
    <msg user_id="101">
        <data>Hello, how are you?</data>        
    </msg>    
</icb_ws>

Code:

 				
import icbxml.*;
				..................
							   try 
				{
				
					
					JAXBContext jc = JAXBContext.newInstance( "icbxml" );
				
					// create an Unmarshaller
					Unmarshaller u = jc.createUnmarshaller();
					outputPipe.connect(inputPipe);						
						byte[] bytes = xmlData.getBytes();						
				outputPipe.write(bytes);
		
		
		
					JAXBElement<?> poElement = 	(JAXBElement<?>)u.unmarshal( inputPipe );

				
					System.out.println(poElement);
					ICBXML po = (ICBXML)poElement.getValue();
					System.out.println(po);
				
					Login login = po.getLogin();					
					displayLogin( login );
					
				} 
				catch( JAXBException je ) 
				{
					je.printStackTrace();
				} 
				catch( Exception ioe ) 
				{
					ioe.printStackTrace();
				} 
...

		 public void displayLogin( Login login ) 
		 {
			// display the Login
			 System.out.println( "I am here??????" );
			System.out.println( "\t" + login.getUserName() );
			System.out.println( "\t" + login.getPassword() );				
			System.out.println( "\t" + login.getLanguage() );
			 
		}

Any help will be appreciated.

Thanks
