Hi folks!
I'm having the same problem, but with servlets. To summarize, I want to have some
kind of init() method, to perform some startup tasks, but for the whole application.
Right now, in every servlet's init() method I must call a singleton to perform the
job. So the problem is, can I do that some other way?
See below for comments.

OK, is there a servlet equivalent?

Anyhow, it's still repetitive code in every servlet. I'd like something more
automatic.
Thanks,
