Whoops, just noticed a problem with this pseduo-code, the parameter
name in the first line is wrong, it should be:
String teamNameCSV = config.getInitParameter("team");
I copied and pasted it from elsewhere in the post I was responding to,
either it was incorrect there too, or it was in a different context.
Still, my bad, I should've noticed it then.

Sounds like you've done something similar :-). In fact, my code does
use that class too. (Actually, a roll-my-own, slightly modified
version of it, since there was some behavior of it that was
problematic for the way I needed it to work -- I think it had to do
with when there were two delimiter characters in a row --
e.g. "GoodGuys,,Enemy" -- I wanted it to return an empty string, but
instead it swallowed up all the delimiters. This is fairly old code,
so perhaps that's not right or it's changed.)

Thanks for verifying that.
