Servlet - JSP
Here is my complete code. all my code is running with out any error. the for loop in servlet is running as many times as my checkboxes were checked.the number and price were being read correct. But my total array list is not working fine. its not returning the product when i try printing in the checkout.jsp page. i tried printing the value stored in total arraylist by using total.indexof(0) & total.indexof(1). they are not storing the product. They are returning -1 and -1. please let me know how to resolve it.
Thanks,
