How OWB stores @SessionScoped beans in Web app?

[Thomas Andraschko]

Hi,

I successfully use Tomcat + Memcached Session Manager to replicate my session 
and JSF @SessionScoped beans.
Now i tried to use OWB + Memcached SessionManager and it does not working.

So my questions are: 
How OWB stores CDI @SessionScoped beans in a Web/JSF app? 
Can a OWB application be clustered?

Thanks!
