Error while receiving SOAP envelope from client

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

Greetings !

I just installed SOAP::Lite and decided to check it out, and in the process created the following scripts:

script /var/www/html/soap/soapserver.cgi

#!/usr/bin/env perl5.8.6

use SOAP::Transport::HTTP;
use World;

SOAP::Transport::HTTP::CGI
  -> dispatch_to('World')
  -> handle;
[download]

Module /var/www/html/soap/World.pm

package World;

sub new {
   bless {}, shift;
};

sub HelloPeople {
   my ($self) = @_;

   return "Answer from sub HelloPeople\n";
};

sub GoodBye {
   my ($self,$adjective) = @_;
   return "Goodbye $adjective \n";
}

1;
[download]

After this I started the Apache server.

The following is the soap client(soapClient.pl)

#!/usr/bin/env perl5.8.6
use SOAP::Lite;

my $s = SOAP::Lite
   ->uri('World')
   ->proxy('http://localhost/soap/soapserver.cgi')
   ->HelloPeople()
   ->on_debug(sub{print@_});
print $s->result();

my $s = SOAP::Lite
   ->uri('World')
   ->proxy('http://localhost/soap/soapserver.cgi')
   ->GoodBye("Bad world")
   ->on_debug(sub{print@_});
print $s->result();
[download]

Everything's fine until this point. When I execute the client (soapClient.pl), It spews out the
following errors

not well-formed (invalid token) at line 1, column 1, byte 1 at /usr/lo
+cal/lib/perl5/site_perl/5.8.6/i686-linux/XML/Parser.pm line 187
#!/usr/bin/env perl5.8.6

use SOAP::Transport::HTTP;
use World;

SOAP::Transport::HTTP::CGI
  -> dispatch_to('World')
  -> handle;
 at soapClient.pl line 9
[download]

Anybody has any idea, why is that so.

Thanks in advance

It would appear that this is a problem with the response from the server - you can get more diagnostic information from the client by changing the : `use SOAP::Lite;` [download] to `use SOAP::Lite +trace => 'all';` [download] This should give you enough to see what is going on - or if you can't work it out for yourself then paste the output here. /J\	[reply] [d/l] [select]

I'm not sure what the exact problem is, but I did notice something odd in your client: `my $s = SOAP::Lite ->uri('World') ->proxy('http://localhost/soap/soapserver.cgi') # vvvvvvvvvvvvvvvvvvvvvvvvvv ->GoodBye("Bad world") ->on_debug(sub{print@_}); # ^^^^^^^^^^^^^^^^^^^^^^^^^^ print $s->result();` [download] The method call to the server GoodBye() returns a SOAP::SOM object (a response of sorts), and not the SOAP object (which is a link to the server), so you probably won't get debugging output from the call. I'd suggest instead using something like the following `my $soap = SOAP::Lite ->uri('World') ->proxy('http://localhost/soap/soapserver.cgi') ->on_debug(sub{warn @_}); $som = $soap ->GoodBye("Bad world"); if ( $som->fault ) { warn $som->faultcode() \|\|'', " : ", $som->faultstring()\|\|'', " : ",$som->faultdetail()\|\|'',"\n"; } else { print $som->result(); }` [download] With debugging on, you should get both the HTTP headers that are sent, and the XML payload of the request and response.

I've used the code specified but I still get the same error which I've showed in the earlierpost Below is the output after executing the soap client(without use SOAP::Lite +trace => 'all';) [root@shobhan soap]# perl soapClient.pl POST http://localhost/soap/soapserver.cgi HTTP/1.1 Accept: text/xml Accept: multipart/* Content-Length: 503 Content-Type: text/xml; charset=utf-8 SOAPAction: "World#GoodBye" <?xml version="1.0" encoding="UTF-8"?><SOAP-ENV:Envelope xmlns:xsi="ht +tp://www.w3.org/1999/XMLSchema-instance" xmlns:SOAP-ENC="http://schem +as.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap +.org/soap/envelope/" xmlns:xsd="http://www.w3.org/1999/XMLSchema" SOA +P-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"><SOAP +-ENV:Body><namesp1:GoodBye xmlns:namesp1="World"><c-gensym3 xsi:type= +"xsd:string">Bad world</c-gensym3></namesp1:GoodBye></SOAP-ENV:Body>< +/SOAP-ENV:Envelope> HTTP/1.1 200 OK Connection: close Date: Thu, 03 Mar 2005 10:22:21 GMT Accept-Ranges: bytes ETag: "6c341-85-68808f40" Server: Apache/2.0.52 (Fedora) Content-Length: 133 Content-Type: text/plain; charset=UTF-8 Last-Modified: Wed, 02 Mar 2005 10:59:33 GMT Client-Date: Thu, 03 Mar 2005 10:22:21 GMT Client-Peer: 127.0.0.1:80 Client-Response-Num: 1 #!/usr/bin/env perl5.8.6 use SOAP::Transport::HTTP; use World; SOAP::Transport::HTTP::CGI -> dispatch_to('World') -> handle; not well-formed (invalid token) at line 1, column 1, byte 1 at /usr/lo +cal/lib/perl5/site_perl/5.8.6/i686-linux/XML/Parser.pm line 187 #!/usr/bin/env perl5.8.6 use SOAP::Transport::HTTP; use World; SOAP::Transport::HTTP::CGI -> dispatch_to('World') -> handle; at soapClient.pl line 23 [download] Does this imply that the XML response from the server is not well-formed. Any ideas what might be wrong.. Thanks	[reply] [d/l]
