how to do these?
hi
I'm working on a shopping cart and i'm facing the following problem.could anybody help.
i have a shop cart which shows some lists of products in a table .at the beginning of each row I have included a checkbox which the purchaser can click to indicate if he wants to delete it from the shopcart.how do i handle
A
1.if user clicks one checkbox and then presses a button to delete.
2.if the user clicks on more than one rows of products and clicks the delete button
B.After deletion the remaining items in the shopcart should be shown.
I'm working in servlets.the shopcart fethches data from a temporary database table which is updated on every addition/deletion.
could these things be done without major hassles through servletsand jdbc

what you can do is just keep all the product details in one vector (probaly you can put it in some bean so that vector of productbean)
along with product id.
In the page give the check box name the same (ex : chk)& value as the product id (ex : productBean.getProductId()
when that page is submited with some check boxes checked for deletion then u can get all the product ids to deleted
(tho request.getParameterValue(
now u can loop tho that & u can just remove that from the vactor in session.
finally update all the values in session to data base..
