Shopping Cart - Part 2

[Murat Balkan]

Hi all,
I have seen different posts about placing a SLSB as Facade in front of the Shopping Cart , which is SFSB. I have one question here. SLSB wont remember its state on the next method call. So how will it find the right EJBObject for the Shopping Cart SFSB?
Thanks for your answers,
Murat

Hi Andre,
Can you be more spesific? It is about storing current sessions in a table?
Thanks,

This would work for logged customers, what about not logged customers or users without profiles ?

Besides, doing this you would use much resources in you business tier for users that are just curious about your site and won't buy anything.

Hi Murat,

My advice is not to rush to SLSB as a Facade in front of the Shopping Cart. BTW, the discussions about stateless or statefull beans can become quite emotional at times and therefore you really need to use _your_ own best judgment.

Regards,
Dan

Ok. You could put the state in a HttpServletSession, before service invocation. This is a lighter design than the first one I've suggested.
