I'm new to Seam, I noticed that in all Seam samples, the EJB declared as @Local, that means the EJBs, JSF pages has to be deployed in the same application server, so how to scale the seam applications into multiple application servers? for example, how can I cluster the EJBs and use HA-JNDI?

And also since the conversation back EJB is stateful EJB, that means during the conversation, one EJB instance can only server one client, so how do I scale them up?
