Answer 1

this code is writting 2 files with and the files have to come in one line text , but it is comming in multiple line . thinking some problem in the
if (((String)colNameAL.get(i-1)).equals("text")) {
                                   if (val!=null)
                                        val=val.replaceAll("\n", "\r");
                                        val =val.replaceAll("\r", "@!");
                                   writeField(w, val, 36000);
                              } else {
                                   if (val!=null)
                                   //     val=val.replaceAll("\n", "\r");
                                        val=val.replaceAll("\n", "@@");
                                   writeField(w, val,(int)metaData.getColumnDisplaySize(i));
                              }//// i am trying to repalce with " \r " still it is throwing error.
