in reply to Apache::Session help storing a complex data structure

The docs for Apache::Session say that Storable (and more specifically nfreeze and thaw) are used to serialize the data. But when I try to freeze a Tree, I get a fatal error. 
use strict;
use warnings;

use Tree         qw( );
use Storable     qw( nfreeze thaw );
use Data::Dumper qw( Dumper );

my $tree = Tree->new( 'root' );
my $child = Tree->new( 'child' );
$tree->add_child( $child );

print(Dumper(thaw(nfreeze($tree))));

Are you getting any errors? I haven't tried actually using Apache::Session. Can that be used from a command line script?

    Thankyou for replying,and Yes, the Command line script works. But, you are correct - the problem is with serializing the Tree, and not Apache::Session. I couldnt catch it myself.


    So, the only option with me is: creating/using another data structure?

    It would have been immense help, if Tree could work.

    Thanks!
