Since you're calling from Perl, I'd recommend 2. if possible since
that's easiest. That'd limit you to just capturing the output/error
streams from the Java program however. You'll need to use the Perl
backticks rather than 'system' (or maybe even IPC::Open3 if you want
to winnow out stdout/stderr). See perlop, perlfaq's etc. for more
about the backtick operator.

If something more elaborate is required such as instantiating a Java
object and calling its methods, you'll need Inline::Java.

JPL, I think, is limited to embedding Perl in Java. It does that very
well and is best used in legacy Java apps which need to leverage
something Perl does better than Java.


Hope this helps,
