I don't believe that only having a class file excludes Inline::Java.
You can either tell Inline::Java to study the enclosing class:
use Inline (
Java => 'STUDY',
STUDY => ['your.class.name.here'],
AUTOSTUDY => 1,
...or you can write your own wrapper code using Inline::Java that calls
the method and call the wrapper from Perl.

When I had to do this, we weren't able to get Inline::Java to work
(proprietary Corba client libraries that needed to override built in
classes.... ick) so we wrote a small server that listened on a TCP
socket and accepted commands (eg, "provision 18.104.22.168 username
password you_are_an_eggbeater")... but don't go there if Inline::Java
works it's clunky and fragile.
Another thought: you could use XMLRPC... but that might be over-kill :)
