multiLinefile and multiple ineAggregators

[tdi300]

all,

I am using spring batch to write a fixed length file. So far I managed to write a fixed length single line file and also a multi Line file. I am trying to write a file made up from multiple classes and ineAggregators. Moreover one of the class to write has a list of times which also needs to be presisted. Below is an example of the dummy classes I am using for my POC :

 
public class Account{

	private long accountNumber;
	private float balance;
       }

public class personDetails {

	private String name;
	private String surname;
	private String ID;
	private int age;
}
public class Customer extends personDetails{
	
	private String customerID;
	
	private List<Account> accountList;
}

Getters and setters where omitted to increase readability. I would require the file in the following format :

customerNAme customerSurname

Account1 balance
Account2 balance
account 3 balance

which sample I could follow from the springbatch samples?

thanks
