Question

I have this code :

private String delete(HttpServletRequest req, HttpServletResponse res, Seller seller) throws Exception {

    //check data
    if(req.getParameter("equipmentId") == null) {

    throw new Exception("equipmentId undefined");

}

//build
Equipment equipment = new Equipment(Integer.parseInt(req.getParameter("equipmentId")));

//delete
dbEquipment.delete(equipment);

//remove in array list
for(int i = 0; i < seller.getListEquipment().size(); i++) {

    if(seller.getListEquipment().get(i).getId() == equipment.getId()) {

        seller.getListEquipment().remove(i);

    }

}

//response
return "ok";

}

The seller attribute passed is from the HTTPSession : ((Seller) req.getSession().getAttribute(“user”))

This code update my object Seller fine offline but online the update doesn’t show up, it’s still the old object/ArrayList.

Answer 1

Try saving object back into session after you update it’s contents.
