Hi,
The aim is for atttaining multiple selection of items from a catalog displaying list of items. I will create a new session and also create a new shopping cart if not created. In the Shoppingcart.java I am using a vector to store multiple selection selections.
I add the shopping cart name as one of name/value pair in session. I call the addItem method of my shopping cart when I click new item.
I am getting a run time exception saying Class java.Util.AbstractList not found when I invoke my catalog. I have no idea why java.Util.AbstractList is asked for.
Kindly help out with the problem or any other way for shopping cart using HttpSessions. U can also mail me at shivanandh@nagar.com.
Thanks in advance,
shiva
