Remember that your client doesn't talk directly to your bean: it talks to
container-generated implementations of your Home and Remote
interfaces. This allows the container to perform transaction, security,
and robustness housekeeping chores for your beans. When your
ejbFindByPrimaryKey returns PersonPK, the container maps that to an
instance of your bean class and calls ejbLoad on that instance, then
arranges for that instance to be wrapped by an implementation of the
bean's remote interface and returns that interface instance. This is a bit
simplified, but I hope it explains what's going on.
