delphi standalone webservice returns http error when consumed through php

I'm pretty new in WS programming.

I created WS (that I picked the base from http://www.digicoast.com/delphi_soap_standalone.html) using delphi-7

When I consumed it through XAMPP php nusoap that is installed to my PC, it worked well and I got the requested result.

But when I consumed it through php nusoap on my web hosting, it returned nothing.

When I put debug in the php codes, it says: HTTP Error: Could开发者_运维百科n't open socket connection to server. Error(110): Connection timed out.

Here is my php codes:

    <?php
    require_once('../lib/nusoap.php');
    $aparams = 'kode_query='.'TRIPS_ALL'.'&'.
               'kode_user='.$username.'&'.
               'kode_id='.$uid;
    $client = new nuSoap_Client('http://110.139.181.78:9696/wsdl/IVSoftWS');
    $xml_data = $client->call('GetXMLDataTable',$aparams);
    echo '<h2>Debug</h2>';
    echo '<pre>' . htmlspecialchars($client->debug_str, ENT_QUOTES) . '</pre>';
    echo '<h2>Error</h2>';
    echo '<pre>' . htmlspecialchars($client->getError(), ENT_QUOTES) . '</pre>';
    ?>

Info: my web hosting using php 5.2.9, while my XAMPP using php 5.3.1

Question: How can I get the same result through web hosting php codes?

Any helps are really appreciated.

Have you checked the firewall settings? The server seems to run on port 9696, this port needs to be opened on the server (more precise: the server which runs the Delphi 7 web service server app) for incoming connections.

To verify, you can use a web browser (or wget) from a different computer, and try to open the service URL.
