[kanewilliam7777]

I have created WSDL file connect the file with PERL soap method. After the exection i get the below error message

"not well-formed (invalid token) at line 1, column 1, byte 1 at /usr/lib/x86_64-linux-gnu/perl5/5.26/XML/Parser.pm line 187." .

Please let me know have to fix the issue.

soap-client.pl

#!/usr/bin/perl -w
#use SOAP::Lite +trace => ‘debug’;

use SOAP::Lite;
my $client = SOAP::Lite
->service('http://localhost/soap/perl/marketplace.wsdl');
my $result = $client->login( 'test_user', 'test_password' ); 


#~ my $result = $client->sayHello('');

print $result;

soap-server.pl

#!/usr/bin/perl

function login( $login, $password )
{
  return $login;
}

function doFilter( $params )
{
  return "some string";
}

marketplace.wsdl

        </port>
    </service>
</definitions>

finally run the soap-client.pl file return below error message.

"not well-formed (invalid token) at line 1, column 1, byte 1 at /usr/lib/x86_64-linux-gnu/perl5/5.26/XML/Parser.pm line 187." .

SOAP::Lite expects something that looks like XML in the reply, but at least XML::Parser doesn't think that it gets XML back.

Your next step is to look at what exactly comes back from the other end.

You already have a line # use SOAP::Lite +trace => ‘debug’; in your code, but that doesn't match what the SOAP::Trace documentation suggests. Maybe changing that line to the following gives you more output that gives you a hint where things to wrong?

use SOAP::Lite +trace => 'all';

What you are looking for is likely the response from the server. Maybe the server sends an HTML error message, or some JSON or whatever.

Hi,

It's sent html error message. Now i have enable the "use SOAP::Lite +trace => "debug";".

So, this response means that your web server is not set up correctly and is not running your server Perl script.

Your next task is to configure your web server so that it runs your Perl script when you go to that URL.

Its legit like use SOAP::Lite +trace => 'debug', readable => 1;
