I am achitecting a mutitiered aplication with a ejb-layer, web app. layer with 2 controllers: one for browser clients and one for rich web clients.
I am wondering about the benefits/minuses of the following designs:
- having 3-4 SLSB as session facades/bus. delegates (like Cade book) - this is my current design
- having SFSB instead (like Petstore)- blueprint best practice recomandation (stated at least 10 times on some pages ;-)
- how each of these would integrate with the "proxy controller (web-app) - ejb controller (ejb)" strategy (like Petstore). Do I use one for each facade??? :roll:
Please comment

I'd drop the second controller... I use the delegate/service idea also.

You will need the two controllers no doubt since they handle two different clients and thus two different protocols are involved. However, you will only need SFSB if you must manage state for a client. Which doesn't seem like a requirement.
 
I've got no option but to sell you all for scientific experiments. Or a tiny ad:
