[ic] Want to use new module/library in embedded Perl code

[Timothy Cassidy]

I'm trying to use this JVM module/library that I have working for perl,
but I can't seem to "use JVM" within any embedded perl code I write.
Further I can't access this JVM module/library from within any subroutines
within my interchange.cfg file.

I tried digging up everything I could on user tags or interchange tags.

But the majority of information I found on perl code in the
interchange.cfg file was concerned with defining perl subroutines.

The best I was able to do was create a GlobalSub in the interchange.cfg
file:

GlobalSub <<EOF
sub count_orders {
return "this is returned from count_orders subroutine.\n";
}
EOF

However, I wasn't able to call this subroutine from within any of my
embedded perl code:
[perl sub]
return count_orders();
[/perl]

So then I tried creating a regular subroutine in the interchange.cfg file:
Sub <<EOF
sub sort_cart_by_quantity {
my $out = 'This is a test!!!';
return $out;
}
EOF

But again I couldn't call it from my embedded perl code in my html pages:
[perl]
return sort_cart_by_quantity();
[/perl]

Anyway, now I am a bit stumped.  The majority of reading I did on usertags
was in the icconfig.pdf and ictemplates.pdf.  You'll notice that neither
of my subroutines use the JVM module/library I was talking about.  This is
because I wanted to get a regular subroutine working before I tried use
JVM.  I'm not sure if this is what you intended when you said to put a
user tag in my interchange.cfg file.  If it isn't I apologize, but
information seems fairly scarce on the topic of usertags in the
interchange.cfg file.  This was all I could find:

---------------------------------------
7.42. UserTag *global*
This defines a UserTag which is global in nature, meaning not limited by
the Safe.pm module, and is is
available to all Interchange catalogs running on the server. Otherwise,
this is the same as a catalog UserTag.
---------------------------------------

Anyway, I am either lacking the documentation or I'm just not thinking
this through correctly.

Thanks,
Tim

PS I have the following manuals:
icbackoffice.pdf
iccattut.pdf
icconfig.pdf
icdatabase.pdf
icinstall.pdf
icintro.pdf
ictemplates.pdf
