SOAP::Lite returning strange value

shonorio has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I'm trying to get a array and hash value from one SOAP Web Services Server without success.

When try to get a hash, I receive 'Odd number of elements in hash assignment at C:\Temp\SOAP\client.pl line 9.' message, or just 1 element from a array variable with no message.

Looking at the dump (after turn on trace on client) I could see all elements of array and hash received from server. Because this maybe I must have to turn on something on client to get the correct values.

My codes are bellow, and I'd like your help to show me where are my bugs.

# Server system
# This is a test of one Web Service Server
use strict;
use SOAP::Transport::HTTP;
use Demo;

my $port = 8080;
my $host = 'localhost';

SOAP::Transport::HTTP::Daemon
    ->new(LocalAddr => $host, LocalPort => $port, Reuse => 1)
    ->dispatch_with({ 'urn:Demo' => 'Demo' })
    ->objects_by_reference('Demo')
    ->handle;
exit;

# The package demo !
package Demo;

use subs qw( Sub1 Sub2 );

sub Sub1
{
  my %Test= ( 'Test01' => 1,
              'Test02' => 1,
              'Test99' => 1 );
  return %Test;
}

sub Sub2
{
  my @Test = qw (2 3 4 5 6 7 8 9 10);
  return @Test;
}
1;

# Client side
use SOAP::Lite;

my $endpoint = shift || 'http://localhost:8080';
my $soap     = SOAP::Lite->uri('urn:Demo')
                         ->proxy($endpoint);

my %Test = $soap->Sub1()->result;

foreach my $Key01 ( keys %Test )
{
  print "Key : $Key01\n";
}

Thanks all.

Looking at google, I found on dbForum on problem like this, where was recomended to change the return code. The new code recomended will look like: # The package demo ! package Demo; use subs qw( Sub1 Sub2 ); sub Sub1 { my %Test= ( 'Test01' => 1, 'Test02' => 1, 'Test99' => 1 ); return ( 1, \%Test ); # return changed } sub Sub2 { my @Test = ( qw (2 3 4 5 6 7 8 9 10) ); # return changed return (1, \@Test); } 1; # New Client !!!! # Client side use SOAP::Lite; use Data::Dumper; my $endpoint = shift \|\| 'http://localhost:8080'; my $soap = SOAP::Lite->uri('urn:Demo') ->proxy($endpoint); my ( %Test01, @Test02 ); if ( $soap->Sub1()->result ) # First get 1 { %Test01 = %{$soap->Sub1()->paramsout}; # and then hash } if ( $soap->Sub2()->result ) # First get 1 { @Test02 = @{$soap->Sub2()->paramsout}; # and then array } print Dumper ( \%Test01 ); print Dumper ( \@Test02 ); [download] Now i'd like know your opinion if it's the best way to implement one Web Service.

my ( %Test01, @Test02 );

if ( $soap->Sub1()->result )  # First get 1
{
  %Test01 = %{$soap->Sub1()->paramsout}; # and then hash
}

if ( $soap->Sub2()->result )  # First get 1
{
  @Test02 = @{$soap->Sub2()->paramsout}; # and then array
}

print Dumper ( \%Test01 );
print Dumper ( \@Test02 );
