von Scriptlet in JSF Managed Bean Problem konvertieren

Question

Ich versuche, diese scriptlet code in JSF-Klasse zu konvertieren.

Die Codeansicht

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

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

und der Java-Code

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; 
} 

Wenn ich scriptlet Code ausführen, bin ich die Antwort als bekommen "Der Server diese bekam: Hallo!"

Wenn ich den JSF-Code ausführe, bekomme ich diese Antwort nicht. Bitte korrigieren Sie meinen Fehler

Vielen Dank im Voraus

Ich korrigiere meine Antwort. Das Problem ist die Verarbeitung des Eingabestroms. Hier ist der feste Code:

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);
