load-balancing

I am wondering conceptually how load-balancing works on the EJB-level (not web session replication) with Java EE containers like Glassfish. From what I have gleaned your remote interface is a proxy that delegates your call to one of many servers you may have in an environment.

If things fail are they supposed to be able to "finish" on another server? I want to understand the basic theory behind this load balancing, why is it better than a bunch of servers all running a plain web application with session affinity on a load-balancer?

Eager / auto loading of EJB / load EJB on startup (on JBoss)

as seen on Stack Overflow - Search for 'Stack Overflow'
EJBs seem to be loaded lazily - whenever accessed. However, I want to initialize them eagerly - i.e. whenever the container starts-up. How is this achieved (in JBoss in particular) This topic gives some hints, but isn't quite satisfactory. >>> More
ClassCastException When Calling an EJB that Exists on Same Server

I have 2 ejbs. Ejb-A that calls Ejb-B. They are not in the same Ear. For portability Ejb-B may or may not exist on the same server. (There is an external property file that has the provider URLs of Ejb-B. I have no control over this.) Example Code: in Ejb-A EjbBDelegate delegateB = EjbBDelegateHelper… >>> More
