Hi Patrick, thanks for the quick response.
I'm looking at the POD now.
I see that you're creating a pi, then doing pi.eval, which I believe is
doing a perl eval{} around the string being passed.
do you have any examples of calling a perl module? (i tried to find
something in the tests) Maybe even walking a java variable?
Thanks
Jay
