 JEditPane   XD   =   new   JEditPane(); 
                  XD.setContentType( "text/html ");

                  XD.setEditorKit(kit); 

                  HTMLDocument   doc   =   (HTMLDocument)XD.getDocument(); 
                  File   f   =   new   File( "sample.html "); 
                  try   { 
                          FileInputStream   reader   =   new   FileInputStream(f); 
                          kit.read(reader,doc,0); 
                  }catch(Exception   e)   { 
                          e.printStackTrace();
