may m doing mistake in code.

here code 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 code 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 main gui these

public void appendreceivedmessages(string s) {             try {   document doce = jtextpane1.getdocument();   doce.insertstring(doce.getlength(), s+"\n", null);    } catch(badlocationexception exc) {    }   } 

this obvious - not sure if qualifies answer. anyway

why doing gui.appendreceivedmessages(""+doc); ? causing doc object's default tostring appear. hope helps

edit:

so can here

i guess can : note styleddocument's insertstring api updates view. meaning provides output need on jtextpane so:

doc.insertstring(doc.getlength(), "\t " + "you" + " : " + gui.getsendmessage() +("\n \t "+dateformat.format(date)) ,style);

is sufficient bring output on text pane. remove call gui.appendreceivedmessages(""+doc);

i believe aim display message text on text pane component - jtextpane1. need update property of jtextpane1 that. not need update else. if need send text data around, text object , pass around methods expects value : example :

string text = jtextpane1.getdocument()                 .gettext(0, jtextpane1.getdocument()                              .getlength());  amethodthatexpectsastring(text);
