spring - JSP/JSTL change value member of array -


I want to change the value of the array in JSP / JSTL which have been created in the controller. How can i do 

  if (_shop_commisions! = Null) {double [] _sum = new double [6]; Model.addAttribute ("zodiac", _ sum); }

JSTL 

  & lt; C: set var = "sum [0]" value = "4" /> $ {Sum [0]} // is showing it 4.0   
 
 
 You are doing Setting a variable named "sum [0]" and value 4 If you want to change the model then you have to interact with the model.  
  $ {sum [0] = 4}
