Session within session

[Ashish Malik]

I need to implement a shopping cart in my app. Its only allowed for registered logged in users.

So a user logs in and may shop or do other stuff...so i need to maintain a user's session and a shopping cart session within that session.
And when user checks out ...he doesnt get logged off...i mean when shopping cart session gets invalidated....user session is still preserved!

Any help...

The way I see it here, there is actually only one session. Inside that session, you may store information about the user and also the shopping cart information. When the user checks out, you can remove the shopping cart attribute from that session. And when the user logs out, you finally invalidate the session.

Thats what i thought before...but shopping cart attribute may contain or most of the times will contain many other attribute like items purchased and their quantity.

Any way to implement that...

And i also dont want to trace for attribute for each item purchased and delete them one-by-one. Rather i want deactivate or invalidate something so that all item attribute would get invalidated.

You can create a class for your shopping cart and store it in the session.

    
public class MyShoppingCart { ... }

session.setAttribute("SHOPPING_CART", myShoppingCart);

At this point, this is just an object modeling exercise.
