That depends upon how they are obtaining database connections. If they
are using the driver directly and NOT using a pool (why would they use a
pool if they have a policy NOT to use it?) then there is likely nothing
you can do.
Are you able to look at the code? Are you able to look at the
configuration? Specifically, the META-INF/context.xml file in the
application and conf/server.xml for the server.
If we can find a "pool" configuration in there, it's possible it just
has insane limits like maxActive="1000000000" or something like that.

Chris,
Not pooling connections will very likely negatively affect performance.
When you say "they ... have an issue with connection pooling" do you
mean that they have a technical problem, or do you mean that there is
some ill- conceived policy against them?
Oh, maybe they are paranoid about cross-client leakage between
connections. Well, if the application can't be trusted not to leak
that kind of info, then it can't be trusted to make the connections
properly in the first place.

Hard to say what their issue is. We've asked about implementing it before,
but they don't support it. You know how software companies are. Maybe
they had a technical problem with it years ago and have just not revisited it.
They're stuck in a rut and there is too much inertia to get them out of it.
