convertir de scriptlet a problema de frijol administrado JSF

Question

Estoy tratando de convertir este scriptlet code a la clase JSF.

El código de la vista

<f:view> 
<h:form binding="#{jsfSocketClient.form}"> 
    <h:outputText binding="#{jsfSocketClient.text}"/> 

</h:form> 
</f:view> 

y el código java

private HtmlForm form = new HtmlForm(); 
private HtmlOutputText text = new HtmlOutputText(); 

public HtmlForm getForm() 
{ 
    System.out.println("instance: "+FacesContext.getCurrentInstance().getResponseWriter()); 
    ResponseWriter writer = (FacesContext.getCurrentInstance()).getResponseWriter(); 
    try{ 

     int character; 
     Socket socket = new Socket("127.0.0.1", 8765); 

     InputStream inSocket = socket.getInputStream(); 
     OutputStream outSocket = socket.getOutputStream(); 

     String str = "Hello!\n"; 
     byte buffer[] = str.getBytes(); 
     outSocket.write(buffer); 
     char characters = 0; 
     while ((character = inSocket.read()) != -1) { 
      text.setValue((char)character); 
      //writer.write((char)character); 
      //characters += (char)character; 
     } 
     //text.setValue(characters); 
     if(str.equalsIgnoreCase("bye")) 
       { 
        socket.close(); 
       } 
    } 
    catch(Exception e) 
    { 
     e.printStackTrace(); 
     text.setValue("You must first start the server application (YourServer.java) at the command prompt.");   
    } 
    return form; 
} 

Cuando corro código scriptlet, estoy recibiendo la respuesta como "El servidor dieron esto: ¡Hola!"

Cuando ejecuto el código JSF, no obtengo esta respuesta. Corrija mi error

Gracias de antemano

Corrijo mi respuesta. El problema es el procesamiento de la corriente de entrada. Aquí está el código fijo:

String response = ""; 
    try { 

     Socket socket = new Socket("127.0.0.1", 8765); 

     Reader reader = new InputStreamReader(socket.getInputStream()); 
     OutputStream outSocket = socket.getOutputStream(); 

     String str = "Hello!\n"; 
     byte buffer[] = str.getBytes(); 
     outSocket.write(buffer); 

     CharArrayWriter result = new CharArrayWriter(); 
     char[] buf = new char[4096]; 
     int charsRead = 0; 
     while ((charsRead = reader.read(buf)) != -1) { 
      result.write(buf, 0, charsRead); 
     } 
     response = result.toString(); 

     if (str.equalsIgnoreCase("bye")) { 
      socket.close(); 
     } 
    } catch (Exception e) { 
     e.printStackTrace(); 
     response = "You must first start the server application (YourServer.java) at the command prompt."; 
    } 
    text.setValue(response);
