This is probably not exactly the solution you're looking for but if you're
ok with running JavaServer and aren't afraid of a few lines of Perl code
you might want to look at http://search.cpan.org/search?dist=Java. It's a
complete Perl interface to a local or remote JVM. Something along the lines of:

use Java;
my $java = Java->new;
my $your_app = $java->create_object('gr.iti.yourApp');
$java->do_event($your_app, \&dtd2xsd);

sub dtd2xsd {
  my $app = shift;
  # call the script from Perl space
  # and return the value by setting it on your object

# simplistic event loop
while(1)  {
  last if not defined $java->go;

It's a bit of a hack because your Java app will have to generate an event
to call the Perl code, and the above Perl program + JavaServer will have to
run continuously if you want to have the functionality available at any
time. Another option you might want to look into is
http://search.cpan.org/search?mode=module&query=jasmin which generates
Jasmin assembler from Perl code but I don't know how complete/stable it is,
and chances are you'll need a fairly recent Perl.
