Here are some very rough guidelines, not clear examples :-).
To be practical, I'd say it depends on the context of the project
you're doing. If this is just a one shot deal, a relatively small
project, one not likely to get a lot of traffic/usage, and the
auxiliary functions you mention aren't to be used elsewhere (e.g. in
other servlets or applications), then it's probably OK to throw it all
in there. That will likely be the most efficient performance-wise.
On the other hand, if this is a large project, long-term with a lot of
maintenance/updates, it will see a lot of traffic/usage, and/or the
auxiliary functions may/will be used elsewhere, then you probably want
to spend more time designing things, which will likely mean more
modularity and keeping things separate that don't belong together.
This may not be as efficient performance-wise, but it has advantages
in terms of maintenance, scalability, robustness, etc.
Personally, I'd very rarely go with the former approach, preferring to
try to set things up modularly even with relatively small projects.
But sometimes that can be more tedious, and you have to be practical.
Another rule of thumb for servlets is that you should think of them as
a web gateway to an application, and only things that are part of that
request/response transaction should go there -- and anything that's
more inherently part of the application shouldn't go there.
