Regarding Headers

[anayyar82]

Hello Ted, i want to add the header as well, i am not sure where i can add it. when i tried to write inside record reader, its coming but attached with all the rows. Can you please guide where can i call the get header function.
my final output is CSV including header.

public static String getRecordHeader(ExternalRecord externalRecord){

  StringBuilder strBuilder1 =  new StringBuilder();

  String headerFields = "";
  for (ExternalField field : externalRecord.getRecordFields()) {
    strBuilder1.append(field.getCobolName().toString()+",");
  }
  headerFields = strBuilder1.toString()+"\n";

return headerFields ; 

}

can you please tell where can i call the function so that i will get it on the top of file only.
