Statefull Session Beans and Entity Beans

[Suresh Bansal]

Hi,
Their is a lot of folk lore that statefull session beans and entity beans are very expensive and should not be used.
So, should we rule out their usage in our design alltogather or can we use them in some cases. I feel that we could use entity beans for master data.
Also the functionality of statefull session beans can also be acheived by using servlet session. Which one is better. I think session beans as they shall be more scalable.
Thanks,
Suresh.

Hi,
Your link is most help full and clarifies the concepts.
What are your views on use on Entity Beans.
Their is a thinking that entity beans are very expensive and should not be used.
So, what should be cases where it should be used.
According to me it should be used in case of master data or if data is used concurrently by many clients.
What do you say ?
Suresh.

well... not sure.. there's a lot of controversy around this topic. if you go to www.theserverside.com there's a bunch of topics regarding this.. Ed roman's Mastering EJB book also explains a bit about this.. maybe if we get a more experienced developer we both can really clarify our concepts...
any ideas guru's?
