here peter is revceiver and Jhon is sender

enter image description here

may be I m doing some mistake in code.

Here is the code for Sender

DateFormat dateFormat = new SimpleDateFormat("HH:mm:ss\n\t   dd/MM/yyyy ");
        Date date = new Date();

        StyledDocument doc = GUI.jTextPane1.getStyledDocument();
        Style style = GUI.jTextPane1.addStyle("a style", null);
        StyleConstants.setForeground(style, Color.red);

    try { 

        doc.insertString(doc.getLength(), "\t  " + "You" + " : " + GUI.getSendMessage() +("\n \t   "+dateFormat.format(date)) ,style); 
        GUI.appendReceivedMessages(""+doc);
        }
    catch (BadLocationException e){}

Here is the code for Receiver

DateFormat dateFormate = new SimpleDateFormat("HH:mm:ss\ndd/MM/yyyy ");
            Date datee = new Date();
            StyledDocument doc1 = GUI.jTextPane1.getStyledDocument();
            Style styler = GUI.jTextPane1.addStyle("a style", null);

             StyleConstants.setForeground(styler, Color.blue);

            try { doc1.insertString(doc1.getLength(),"recevier" ,styler); 
                GUI.appendReceivedMessages(fromHeader.getAddress().getDisplayName() + " : "
                    + new String(request.getRawContent()) +("\n"+dateFormate.format(datee)));                
            }
            catch (BadLocationException e){}

here is Main GUI where I get these

public void appendReceivedMessages(String s) {
            try {
  Document doce = jTextPane1.getDocument();
  doce.insertString(doce.getLength(), s+"\n", null);
   } catch(BadLocationException exc) {

  }


}

This is so obvious - not sure if qualifies for an answer. Anyway

Why are you doing GUI.appendReceivedMessages(""+doc); ? that is causing the doc object's default toString to appear. Hope that helps

EDIT:

so what can I do here

I guess you can do it like this : Note that StyledDocument's insertString API updates the view. Meaning it provides you the output you need on JTextPane so:

doc.insertString(doc.getLength(), "\t " + "You" + " : " + GUI.getSendMessage() +("\n \t "+dateFormat.format(date)) ,style);

Is sufficient to bring the output on to the text pane. Remove the call to GUI.appendReceivedMessages(""+doc);

I believe your aim is to display the message text on the text pane component - jTextPane1. you just need to update property of jTextPane1 for that. You do not need to update anything else. If you need to send the text data around, just get the text from that object and pass it around to methods that expects the value : example : 

String text = jTextPane1.getDocument()
                .getText(0, jTextPane1.getDocument()
                             .getLength());

aMethodThatExpectsAString(text);
