Re: How to run servlet for every 30 minutes in Tomcat 4.1.30

[Frank W. Zammetti]

Your just lending weight to what I said... Don't play with threads in a 
servlet contain unless your really sure you have to and are really sure 
you can do it safely :)

(I'm not sure I knew init() could be called more than once, certainly I 
didn't remember when I wrote that, so excellent point)

Yes and no. ;)
It's possible to use a servlet's init() method for this; but per the
spec, containers are free to initialize a servlet class as many times as
they see fit.
Much safer to use a ContextListener in this case, as those are triggered
only on app (context) startup and shutdown.
