in reply to Java module

The latest release of the Java module is 9 years old. It doesn't seem to be actively maintained any more (there are bugs on its bug tracker eight years old without any action on them), and seems to fail its own test suite on all platforms consistently.

I'd recommend trying Inline::Java instead which is more actively maintained (though the last release is still more than 2 years old). Yes, it has some pretty long-running bugs too, but at least the module maintainer seems to be taking action against some of them (most are marked open and have replies from the maintainer). It is well reviewed, and people seem to be using it (including me), unlike the Java module.

package Cow { use Moo; has name => (is => 'lazy', default => sub { 'Mooington' }) } say Cow->new->name

    Hi tobyink

    Thanks for the comments.
    I have Inline::C module installed in my system.

    Despite the environment variables $JAVA_HOME and $PERL_INLINE_JAVA_J2SDK are set properly, I couldn't be able to install Inline::Java
    I wonder why it doesn't recognize JAVA_HOME?

    Please see the following logs.
    $ perl -e ' while(my($k, $v) =each(%ENV)) { print "$k\t$v\n" if $k =~ /J/; } ' JAVA_HOME /usr/lib/jvm/default-java PERL_INLINE_JAVA_J2SDK /usr/lib/jvm/java-6-openjdk-i386 $ $JAVA_HOME/bin/java -version java version "1.6.0_24" OpenJDK Runtime Environment (IcedTea6 1.11.5) (6b24-1.11.5-0ubuntu1~12 +.04.1) OpenJDK Server VM (build 20.0-b12, mixed mode) $ $PERL_INLINE_JAVA_J2SDK/bin/java -version java version "1.6.0_24" OpenJDK Runtime Environment (IcedTea6 1.11.5) (6b24-1.11.5-0ubuntu1~12 +.04.1) OpenJDK Server VM (build 20.0-b12, mixed mode) $ sudo cpan Inline::Java CPAN: Storable loaded ok (v2.27) Reading '/home/parthiban/.local/share/.cpan/Metadata' Database was generated on Sat, 16 Feb 2013 01:07:21 GMT Running install for module 'Inline::Java' Running make for P/PA/PATL/Inline-Java-0.53.tar.gz CPAN: Digest::SHA loaded ok (v5.61) CPAN: Compress::Zlib loaded ok (v2.033) Checksum for /home/parthiban/.local/share/.cpan/sources/authors/id/P/P +A/PATL/Inline-Java-0.53.tar.gz ok CPAN: File::Temp loaded ok (v0.22) CPAN: Parse::CPAN::Meta loaded ok (v1.4404) CPAN: CPAN::Meta loaded ok (v2.120921) CPAN.pm: Building P/PA/PATL/Inline-Java-0.53.tar.gz CPAN: CPAN::Reporter loaded ok (v1.2009) Welcome to the Inline::Java installation procedure.
