I know that you can set the scope for a bean to be Application, but most
of the docs for it that I have read are pretty vague, so I'll give an
example.
I have certain categories is a db that I want to access and that users
will be accessing frequently. So I'm trying to generate a Yahoo! style
tree listing of categories, which isn't hard to do. However, it doesn't
make sense to keep makiing all these database calls when I could have it
it memory.
So I'm thinking about making a separate bean that will hold all of these
60 categories I have and set the scope on the bean for application.
However, it doesn't seem like my servlets could get access to this bean.
I was thinking req.getAttribute() from a servlet, but I'm not sure that
would work.
Has anyone had any experience doing this? I don't want to session this
info since for each session created a duplicate of the data would be
made.
Thanks,
Jason
