WSO2 & WSE 3.0 MTOM Interop

Hi,     We have a sample which interops with Microsoft Indigo services in http://131.107.72.15/MTOM_Service_Indigo/Soap12MtomUtf8.svc?wsdl. <code> $reqPayloadString = <<<XML <EchoBinaryAsString xmlns="http://xmlsoap.org/Ping"><array><xop:Include href="cid:myid1" xmlns:xop="http://www.w3.org/2004/08/xop/include"/></array> </EchoBinaryAsString> XML; try {     $file_name = file_get_contents("string.txt"); /*  $file_name = file_get_contents("axis2.jpg"); */     $reqMessage = new WSMessage($reqPayloadString,         array("to" => "http://131.107.72.15/MTOM_Service_Indigo/Soap12MtomUtf8.svc/MtomTest",               "action" => "http://xmlsoap.org/echoBinaryAsString",               "attachments" => array("myid1" => $file_name)));     $client = new WSClient(array("useMTOM" => TRUE,                                      "useSOAP" => "1.2",                                      "useWSA" => TRUE));     $resMessage = $client->request($reqMessage);         echo $resMessage->str; } catch (Exception $e) {     if ($e instanceof WSFault) {         printf("Soap Fault: %s\n", $e->code);     } else {         printf("Message = %s\n",$e->getMessage());     } } ?> </code> Could you try this sample and let us know.   Thanks Buddhika
