SOAP::LITE

[neil.holmes]

I am trying to make use of SOAP::LITE for calling Web Services from
Perl.

I have Windows and Linux Installations.

On Windows the following works fine :-

#!/usr/local/bin/perl
use SOAP::Lite;
print SOAP::Lite
-> service('http://neilvmes3:8082/ws/EcsAddEntry?wsdl')
-> TK_ADD_ENTRY('Neil Holmes','Greatest Hits
Volume','CD','9.99','www.proiv.com');

The data is added to the application behind the web services and a
success flag is returned.

The Linux version of the same call :-

#!perl
use SOAP::Lite;
print SOAP::Lite
-> service('http://neilvmes3:8082/ws/EcsAddEntry?wsdl')
-> TK_ADD_ENTRY('Neil Holmes','Greatest
Hits','CD','9.99','www.proiv.com');

Appears to run (no errors) but the application is not updated and no
success flag is returned.

Does anyone have some suggestions as to what might be causing this ? Or
what I can do to try and track down the problem.

Any suggestions very greatfully received.

Many Thanks

Neil

^^^^^^ Why isn't this the same as above?

use SOAP::Lite;

Same versions of SOAP::Lite?

How do you know there aren't any errors? I don't see any error handling
in your example.

Check the logs on neilvmes3's Web server.

Add logging to the service.

Adding +trace (see documentation) will show you what's being sent and
received.

Thanks for this. I have 0.60 on both Windows and Linux.

I have added debug to my script :-

#!perl -w
use SOAP::Lite +trace =>
qw(debug);
print SOAP::Lite
-> service('http://neilvmes3:8082/ws/EcsAddEntry?wsdl')
-> TK_ADD_ENTRY("Neil Holmes",'Greatest
Hits','CD','9.99','www.proiv.com');

And the output is as follows :-

This seems to be telling me that there is no value in the Parameter
(the first value in the Method). How can this be ? I am particularly
puzzled as there clearly is on Windows.

Your advise is much appreciated.

Many Thanks

That looks odd.. Why "Neil Holmes" isn't a string.

Run it from the host that works and compare the output.

Since you have a WSDL, you could also try using 'stubmaker.pl',
which comes with SOAP::Lite, to create a class, which you can
use or peruse it for any helpful code. See 'stubmaker' in
perldoc SOAP::Lite.

Maybe use SOAP:ata to set the properties for all of the attributes:
my @params = (
SOAP:ata->name( ARTIST => 'Neil Holmes' )->type( 'string' ),
SOAP:ata->name( ALBUM => 'Greatest Hits')->type( 'string' ),
etc..
);

print SOAP::Lite
-> service('http://neilvmes3:8082/ws/EcsAddEntry?wsdl')
-> TK_ADD_ENTRY( @params );

Just a guess though. I have to do that when working with services
written in .NET. (
