xml-rpc php/asp communication problem
i've been dabbling with xml-rpc in php and it's all gone swimmingly...

for an exercise, i wrote an xml-rpc server that receives a four digit integer from an xml message and gives it to the unix shell program "cal" (calendar). the xml response contains a lovely formatted calendar for the year.

(i've been using the xmlrpc.inc and xmlrpcs.inc from sourceforge)

with a php client talking to a php server, it is great... lovely calendar in the browser...

next step/the problem:
with an asp client talking to the same php server... it doesn't work...


i get back an error (abbrev.):
"XML error: no element found at line 1"

(i am using David Carter-Tod's xmlrpc.asp include)

i can however get my asp to talk to my asp (different service, mind, as windows doesn't have cal)

before i continue poking about with code and http and xml and server config etc, are there any known issues with this sort of a set up?

re-inspired...
i've just seen reemjacob's post on bigsean's thread... http://forums.devshed.com/showthrea...&threadid=40223 and i've been re-inpired to get this working...

however, my problems seem different to bigsean's... though I checked out the msxml2.dll that reemjacob mentioned to be sure...

here's some code:

the asp client:

<!--#include virtual="/xmlrpc/xmlrpc.asp" -->
<%
on error resume next
'if NOT Request.form("year") = "" then
Dim paramList(1)
paramList(0)=CInt("2002")

' WHAT AM I SENDING TO THE SERVER
Response.write("<pre>" & Replace(functionToXML("mdsxmlrpc.cal", paramList), "<", "<", 1, -1, 1) & "</pre>")



myresp = xmlRPC("http://florence/mds_serv/cal_s.php", "mdsxmlrpc.cal", paramList)
response.write(myresp & "<p>")


' WHAT I AM GETTING FROM THE SERVER
Response.write("<pre>" & Replace(serverResponseText, "<", "<", 1, -1, 1) & "</pre>")

'end if
%>

the php server:
PHP Code:
<?php
require("/webhome/florence/includes/xmlrpc.inc");
require("/webhome/florence/includes/xmlrpcs.inc");


$cal_sig=array(array($xmlrpcString, $xmlrpcInt));

$cal_doc='When passed a four figure year, returns the
calendar for that year.';

function cal($dte) {
global $xmlrpcerruser;
    // get the first param
    $y=$dte->getParam(0);

    if (isset($y) && ($y->scalartyp()=="int") && ($y->scalarval()>=1000) && ($y->scalarval()<10000)) {
        $cmd = "cal ".$y->scalarval();
    }
    else {
        $cmd = "cal ".date("Y");
        // parameter mismatch, complain
        //$err="A four-figure year is required.";
    }
    
    $fp = popen($cmd, "r");
        while (!feof ($fp)) {
            $cal .= fgets($fp, 69);
        }
    pclose($fp);



    // if we generated an error, create an error return response
    if ($err) {
        return new xmlrpcresp(0, $xmlrpcerruser, $err);
    }
    else {
        // otherwise, we create the right response
        // with the calendar
        return new xmlrpcresp(new xmlrpcval($cal));
    }
    

} // end function cal




$s=new xmlrpc_server(
            array(     "mdsxmlrpc.cal" => array(    "function" => "cal",
                                 "signature" => $cal_sig,
                                 "docstring" => $cal_doc
                            )
            )
);






?>



and the full error message:

<?xml version="1.0"?>
<methodCall>
<methodName>mdsxmlrpc.cal</methodName>
<params>
<param>
<value><int>2002</int></value>
</param>
</params>
</methodCall>


<?xml version="1.0"?>
<methodResponse>
<fault>
<value>
<struct>
<member>
<name>faultCode</name>
<value><int>103</int></value>
</member>
<member>
<name>faultString</name>
<value><string>XML error: no element found at line 1</string></value>
</member>
</struct>
</value>
</fault>
</methodResponse>


if anyone has some ideas, i'd be glad to hear them...

i should point out again - the server works fine with a php client... and i can get an asp ("Hello world") client to talk to an asp server okay.

ASP / PHP XMLRPC
Ahhh HA! Finally someone else seems to be having the same set of troubles I am.

At least its returning the xml response with the data wrapped in XML, but its generating basically the same error.

XML-RPC ASP client not talking to PHP Server
Hi,

I know this was over a year ago, but I've just hit exactly the same problem.

did you get any satisfaction getting your ASP client to talk to your PHP server ?

thanks,
Jonathan
