But, I think the main point was that it's faster to
develop the system in Perl. And it is usually going to be more flexable and thus easier to maintain in Perl than Java.
I'd tend to agree with this point, but will concede that it depends on the quality of developers on both sides of the fence; it's possible to write crappy perl that's not maintainable, it's also possible to write GREAT java that is as flexable and maintainable. I believe the latter will take a lot longer, and involve more highly skilled people to write than it will a good (GREAT?) perl version.
