Gene,
That's one of the awkwardness of EJB, that the behavior of load-balancing is
unspecified. So, for example, while for some vendors load-balancing only works
if you reuse the same EJBHome, for other vendors, load-balancing will not work
if you reuse the same home. For example, with some products, load balancing
occurs in the naming service.
I'm not trying to start a debate as to which model is correct (they both have
benefits). I am just pointing out the annoying fact that when it comes to features
above and beyond the EJB spec (such as LB), you may have to write your
application differently depending on the target server. Again, it's awkward,
but that's how it is...
