I'm embarrassed to say this, but the "production" box we're talking about in my case is a single function box with, at present, 1 user utilizing this one batch of jsp pages, 1 or 2 days a week. IOW, it is a *very* lightly loaded box. :0)
We might run into load problems, but they'll be a while off. The plan is to add one user every 1 to 2 weeks up to a grand total of around 90 at the end of the year. And they won't be concurrent users. ;0)
