about storing vales in sessions

[satish]

in session tracking we have methods tod store and retrieve values from session
object..In my program I am storing all the individual products selected by
the user in a session object
using session.putvalue("cart.items", prodselected[i]), but in the next servlet
i need to retrive all the values individually stored by the user in the session
object, so for this

we have session.getValue("cart.items") - it retrieves only one(the recent
stored value), and session.getValueNames();;;but i want to retrive all the
values and there is no method such as

session.getvalues("cart.items")..so how do i do it,


if anyone understood the problem pls help me

satish,

You should be storing the entire *prodselected* array.

session.putvalue("cart.items", prodselected)

and use (Object[])session.getValue("cart.items") to get it.

You should store a data structure in the session object able to handle all
that. An instance of java.io.ArrayList would perform great but as far as
I can remember a class must implement the Serializable interface in order
to be bound to the session object. Take a look at the documentation available
and check it out.

Anyway all you would need to do is to mark your class "serializable" since
no methods need to be written in order to implement that interface.

Hope that helps.
