I am making a little shopping cart using jsp . Now when the ORDER Page comes , it shows product names , prices , and quantity .
When the user selects the quantity and click checkout , the program should calculate the cost of it . Now how can i do that?
I have a form which i am populating with the product name and price , how can i calculate the selected product values?

If you select them using checkboxes, give all the checkboxes the same name, and as value you give it the productId:

<form>

...

<input TYPE=checkbox name=[B][COLOR="#008000"]"product"[/COLOR][/B] value=[B][COLOR="#008000"]"carId"[/COLOR][/B]> car<br/>

<input TYPE=checkbox name=[B][COLOR="#008000"]"product"[/COLOR][/B] value=[B][COLOR="#008000"]"bookId"[/COLOR][/B]> book<br/>

...

</form>

And as you get the "product" out of the request, you get a String array containing the values from the selected checkboxes.

String[] productIds = request.getParameterValues([B][COLOR="#008000"]"product"[/COLOR][/B]);
