I sent to DEV because there was a code question at the bottom.
I am mainly interested to know how to take something that
is stored in the browsers i.e a number and translate that into
a handle for a particular bean.
I was hoping that someone would have intaminate knowledge of
the Handle object and maybe provide some quidence as to
how you could serialize it to a cookie value.
Additionally, I am looking to see if there is anyway to have control
over the Handle. (i.e. If I code a mechanism to distribute my stateful
session bean across all my servers then I want them to have
the same handles.
