However.... if you read servlet spec 2.4, SRV.2.3.4 you'll find the
following direct quote:
"The servlet container is not required to keep a servlet loaded for any
particular
period of time. A servlet instance may be kept active in a servlet
container for a
period of milliseconds, for the lifetime of the servlet container (which
could be a
number of days, months, or years), or any amount of time in between."
I think you should give up on the whole idea of trying to keep a servlet
operating for the life of tomcat. Look at the reasons why you want this
and look at other solutions to those problems.

In j2ee specs, there is no provision for unloading an unused servlet.
Once a servlet has been tarted (load-on-startup or triggered by user
query), i never get unloaded, unless webapp gets unloaded, which
occurs at shutdown or during a redeploy (administrative task)

Hello,
I would like to create one of my servlets to be 'sticky': to be sure
that Tomcat will never try to remove this servlet from memory.
Is <load-on-startup> enough? I know that it will start my servlet as
soon as tomcat starts, but will tomcat ever try to remove such servlet?
E.g. if there will be 1 month of inactivity, or so much requests arrive
that out-of-memory will happen?
Maybe I should create some background thread or socket or whatever?
Any solutions appreciated, thanks in advance.
