Looking for information
Kyle R. Burton
googling. I apologies if my questions are documented somewhere that
i could not find. Pointers to existing information would be greatly
appreciated.
Is JPL still under active development? I see that it is part of the
perl source distribution (up to 5.9.2) though some of the files in the
jpl directory have 1999 dates in them.
My goal is to provide a pool of Perl interpreters within a JVM. From
what I have read perl supports being compiled so that multiple
interpreters can co-exist in the same process/address space. PLJava
(one of the alternatives I found) uses a single static interpreter so
it is unsuitable for my purposes. From what I have been able to read
about JPL I can't determine if it supports this model or not.
I'm also looking at Inline::Java's support for embedding Perl into Java
Any other information, links, anecdotal stories, etc are appreciated.
Thanks for your time,
Kyle R. Burton

JPL is languishing, no longer in vogue apparently. Although
part of the Perl distro, it requires a core patch in order
to work. The patch was made to the core but then went MIA
circa 5.8 as I recall. A colleague in my area did update the
patch to work with an early version of Perl 5.8.x. However,
it hasn't been submitted to p5p. Also, I've been hoping/
fantasizing about working on a nicer install too (with a
configure, Makefile.PL, etc.) instead of the existing
makeshift shell script.

I don't know enough about that to comment.

I've only played with Inline::Java a little but it works well.
That's limited to the other direction though as I recall: embedding
Java in Perl. However, if you have a large legacy Java app, in need
of some embedded Perl to maintain your sanity, you'll need JPL. My
colleague reports JPL has worked wonderfully to provide some Perl
amenities within a huge Java app. Hopefully, JPL won't be circling
the drain for quite a while yet.
