Jan,
I am on vacation right now. I'll take a closer look at your problem when I get
back.
I have not yet tried Inline::Java under mod_perl2. One question
though: are you loading the (Inline::Java) Perl code at parent startup
(using PerlRequire or PerlModule), or are you just loading it normally
with the handler?
