Hi Anurag,
if you SSB is used as proxy for web services then it will go in the integration layer. I had similar doubt following is the link to my post regarding this:-

Hi Alexandre,

This is what I think.

"Basicly in a web-centric Spring application I use the fold architecture :

Web tiers | Business tier | persistance tier
Backing bean <-> Business Delegate <-> Facades <-> Services <-> DAOs

I think that I can keep the same architecture in EJB-centric application (right?)"

IMHO I would include service locator between business delegate and facades. This will decouple web tier from business tier.
DAO are called EAO ( entiry access objects ) now. since you are using session bean you can inject entity manager in the session bean and forego EAO/DAO, however I think its better to use EAOs that way all queries. CRUD operation are not sprinled all over the place.

thanks

Thanks Gladwin and Arpit , you have made it very clear. can you please also confirm that if my dao is implemented as SSB then it should also be in integration tier ?

thanks once again, information you provided really helped me.

Raj
Hi Arpit,

Thanks a lot for letting me know, it really helped, i had been reading documents and getting confused.
So that also means if I have DAO object implemented as SSB then it should also go in Intergeration tier?
I thought all the SSB should be in busines layer.

thanks
Raj
Hi All,

Can someone please explain me if my system is accessing a web service and I have created a session bean as a proxy for web service, should proxy ( stateless session bean) be shown on Intergration Tier or Business tier on component diagram.

thanks a lot

Raj
Hi Jeanne,

Thanks for the reply.
my question is regarding the component diagram, I have been reading about component diagrams for the past one week and all the sources contradict the information.
In my component diagram I am showing packages which contain components, but these components are shared between packages, for example in presentation tier I have 3 packages each containing components, and I have two components which are in all three packages in paresentation tier. Is is ok to that components are shared between packages?

thanks a lot
Raj
Hi All,

I am struggling with component diagram, if I show packages containing components , can I have same components in two packages.

any help or thoughts will be highly appreciated.

thanks
Raj
Hi Gladwin and Kuppusamy,

Thanks a lot for the clarification. you have made it very clear now

thanks once again

Hi Kappusamy,
Thanks a lot , article made it clear. I had been surfing net for quite a while.
I have another question if I am using DAO then where should I show jpa entities in deployment diagram, in DAO layer or business layer. The reason I am confused is because because business layer needs entities for business logic, but in turn uses DAO to access and maipulate them.

thanks a lot

Raj
