Hi:

I'm having a similar trouble, I'm using a PHP PEAR::SOAP server (I think it's the same HelloServer from the example) and I'm using a gSoap C++ client to retrieve the answer from it. The problem I have is that when I print the resulting string it's allways empty. I have the answer from the server, so I believe the call is going fine, so could you tell me if I'm doing something wrong on my code? Thanks.

Norb,
Sorry not had a chance to reply before, Just using a modified version of the
quote example in the samples directory that comes with Gsoap, I have used a
stuct to return , so you can see how they fit in if you need to pass complex
structures around. Let me know if you have any problems.


This is the c++ header file.
<snip>


typedef char * xsd__string;
int ns__sendback (char * password, struct ns__sendbackResponse {xsd__string
_return_;}  * out);

</snip> 

This is the c++ code.

#include "soapH.h" /* include generated proxy and SOAP support */ 

int main(int argc, char **argv)

  struct soap soap;
  struct ns__sendbackResponse q;

    sym = argv[1];
  else

  soap_end(&soap);

and the php server

require_once 'SOAP/Server.php';


class Test1 {
    // Stores instance of PEAR::SOAP Server
    var $soapServer;

    function Test1 ()
    {
        // Switch off notices to all GET

        // Instantiate PEAR::SOAP SOAP_Server
        $this->soapServer=new SOAP_Server;


        // Build the object map (using this instance) + add a namespace

        // Turn on the server

// Start the SOAP server
$test = new Test1;

Have fun

Thanks O for answering my posting. 

That would be great if you could send me a example (like 'hello' below) of
a GSOAP client making a request to a PEAR::SOAP server.
Also, if you have an example of structures or lists that are being passed
as a SOAP response.  I have a MySQL database that is being queried by my
backend PHP code and am wondering how to pass multiple types via SOAP.


Thanks again,
Norb


Here's the corresponding C code which is currently failing:

C Code: 

#include "soapH.h"
#include "ns.nsmap"


const char server[] =
"http://192.168.2.102/test/pear_soap/examples/ws/testserver1.php";;


int main(int argc, char **argv) {
  struct soap soap;
  char result[50];
  char *pass_variable;

pass_variable = result;

soap_init(&soap); 

  soap_call_ns4__hello(soap_new(), server, "",  "bonnie girl",
&pass_variable);


  if (soap.error) soap_print_fault(&soap,stderr);
  else {
    printf("successful");
    printf("result: %s", pass_variable);
  }


return 0;

}

Here's the corresponding PHP server side code: 

<?php
class Test1 {
    // Stores instance of PEAR::SOAP Server
    var $soapServer;


    // Constructor builds PEAR::SOAP Server
    function Test1 () {
        // Switch off notices to all GET
        error_reporting(E_ALL ^ E_NOTICE);


        // Instantiate PEAR::SOAP SOAP_Server
        $this->soapServer=new SOAP_Server;

// Build the object map (using this instance) + add a namespace 

$this->soapServer->addObjectMap($this,'http://www.phppatterns.com#Test1');
        //$this->soapServer->addObjectMap($this,'http://tempuri.org');


        // Turn on the server
        $this->soapServer->service($GLOBALS['HTTP_RAW_POST_DATA']);
    }


    function serverTimestamp() {
        return time();
    }


    function hello($name) {
        return 'Hello '.$name;
    }


    function hello1() {
        return 'Hello from PEAR';
    }
}
?>

Norb,

I can confirm that I have got GSOAP 2.4 & 2.5 working fine with
PEAR::Soap,
but I have only been passing strings around and not really tested any
other 
data types. Apart from Attachments which don't seem to work that well as
PEAR::SOAP doesn't build the options array that gsoap expects, but this
can
be worked around. let me know if you need some code.

I've been trying to get my C++ gsoap client request to work with my PHP
PEAR::SOAP server response.

Has anyone ever tried this and get it to work? Here are the details:

GSOAP request: 

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope
  xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/";
  xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/";
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
  xmlns:xsd="http://www.w3.org/2001/XMLSchema";
  xmlns:ns4="http://www.phppatterns.com#Test1";>


  <SOAP-ENV:Body id="_0">
    <hello xmlns="http://www.phppatterns.com#Test1";>
      <param-1>bonnie girl</param-1>
    </hello>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

PEAR::SOAP response: 

HTTP/1.1 200 OK

<SOAP-ENV:Body>


<ns4:helloResponse>
<return xsi:type="xsd:string">Hello bonnie
girl</return></ns4:helloResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>


Everything looks good except GSOAP doesn't like the <return> tag
according to the following debug message:


Unknown element 'return' (level=3, 1)
IGNORING element 'return'
End element found (level=3) 'return'=''

A more generic question: 

Has anyone ever gotten a C++ SOAP client (any SOAP implementation) to
correct communicate with a PHP SOAP Server (Any SOAP implementation)

Thanks in Advance
