public class Employees1 implements Serializable

  • Still had no coffee, but `minOccurs="0"` perhaps? – Joop Eggen Jan 17 '18 at 07:33
  • Please show us the `Employees1` class and the code where you write the output? Which object(s) are you passing to the `BeanWriter.write()` method? – nicoschl Jan 17 '18 at 07:54

    The config does what you asked it to do. You've asked it to output the same set of employees twice. One with sno "001" and fields name,street,city,zip and once again with sno "005" and only fields "age" and "position". If you don't want duplicate outputs, you should have two lists - one with the employees that you want to output in format 001 and one list that you want in format 002. And they should probably have two different Java classes as well, what's the point of having one Employee1 class if you use it for different purposes with no overlapping fields? – Erwin Bolwidt Jan 17 '18 at 07:57
  • @ErwinBolwidt Keeping two lists is working but order of the objects is not maintained.Is there a way to maintain order of the objects too? Thanks for your response. – sunleo Jan 17 '18 at 08:49
  • I'm not very familiar with this framework, I'm just following your XML logically. But I don't see how you could keep it in order as there is no way for the framework to find out whether you want to output in format 001 or 003. Records have the same Employee1 class and there is nothing that the framework can use to decide the choice of format. Maybe if you had a field "format", and if the framework has support for conditionals, you could make it work that way. – Erwin Bolwidt Jan 17 '18 at 08:56
