Hello, I've been using Inline::Java to do some integration work. Its
been quite successful over all. However, I've come upon a simple task
that I'm either going about completely the wrong way, or I've found a
minor problem.
The short version is I want to convert a perl string into a java byte[]
array. I was planning on using java.lang.String and calling getBytes.
The strings are fairly short, so it should be fine. However, that
doesn't work. In fact, I can't seem to get any methods on a
java.lang.String object to work. I consistently get a
java.lang.NumberFormatException.
Running the following code:
use strict;
use warnings;
use Inline (
Java => 'STUDY',
STUDY => [],
) ;
use Inline::Java qw(study_classes) ;
study_classes(['java.lang.String'], undef) ;
print "imported classes\n";
my $str = java::lang::String->new("Test me") ;
print "Created string obj\n";
print($str->length . "\n") ;
Produces the following results:
imported classes
Created string obj

I'm in the process of reading the code, but I was wondering if this is
just a fundamentally flawed way of getting what I need?
TIA
