Hi, I'm newly here boring you with my PHP5 problem ;-)..... I've a problem with a remote invocation (via PEAR::SOAP) of the method schemaValidateSource of DOMDocument Object. I Have the following SW configuration: Windows XP Home SP2 Apache 2 PHP 5.1.1 libxml/libxml2 2.6.11 libxslt 1.1.7 libexslt 0.8.5 DOM/XML API 20031129 And C:\PHP>pear list INSTALLED PACKAGES, CHANNEL PEAR.PHP.NET: =========================================

I have the SOAP server: __________________________________________________________________________ <?php require_once('SOAP/Server.php'); require_once('SOAP/Disco.php'); class pearsoaptest { public $__dispatch_map = array(); public function __construct() { $this->__dispatch_map['validate_pmif_from_xml_schema'] = array('in' => array('model' => 'String'), 'out' => array('validated' => 'Boolean'), ); } public function validate_pmif_from_xml_schema($model) { $_lres = FALSE; $schema = file_get_contents("http://www.perfeng.com/pmif/pmifschema.xsd"); // The following line will load a local backup copy of pmifschema.xsd if the previous instruction return FALSE // it was tested by me and works fine $schema = $schema ? $schema : file_get_contents("http://www.scienze.univaq.it/Zallocco.Samuel/pmifschema.xsd"); if ($schema) { $dom_model = DOMDocument::loadXML($model); if ($dom_model) { 
			    // the instruction that fail is the following one:
$_lres = $dom_model->schemaValidateSource($schema); // if you disable the previous instruction the code will work fine //$_lres = TRUE; // For example // So I deduced that the call to schemaValidateSource will rise some kind // of fatal error that return an invalid HTTP response to SOAP client } else { // something } } else { // something } return $_lres; } } // Thanks to Harlan Iverson <hjiverson@plauditdesign.com> of php.soap newsgroup // on news://news.php.net for this "sessions" slice of code! // Whitout the session use the client have no way to access class variable from method invocation!! session_start(); $server =& $_SESSION['server']; if( !isset( $server ) ) { 
    $server = new SOAP_Server();
    $webservice = new pearsoaptest();
    $server->addObjectMap( $webservice, 'http://schemas.xmlsoap.org/soap/envelope/' );
} // Thanks a lot Harlan! You save me! if (isset($_SERVER['REQUEST_METHOD']) && $_SERVER['REQUEST_METHOD']=='POST') { 
     $server->service($HTTP_RAW_POST_DATA);
} else { $disco = new SOAP_DISCO_Server($server,'pearsoaptest'); header("Content-type: text/xml"); if (isset($_SERVER['QUERY_STRING']) && (strcasecmp($_SERVER['QUERY_STRING'],'wsdl') == 0) ) { echo $disco->getWSDL(); } else { 
       	header("Content-type: text/xml");
echo $disco->getDISCO(); 
    }
} exit; ?> __________________________________________________________________________ And the client: __________________________________________________________________________ #!/usr/local/bin/php <?php /* NOTICE: In my php.ini file I have set to report all error to a a file */ require_once 'SOAP/Client.php'; class pearsoaptest { public $__dispatch_map = array(); public function __construct() { $this->__dispatch_map['validate_pmif_from_xml_schema'] = array('in' => array('model' => 'String'), 'out' => array('validated' => 'Boolean'), ); } public function validate_pmif_from_xml_schema($model) { $_lres = FALSE; $schema = file_get_contents("http://www.perfeng.com/pmif/pmifschema.xsd"); // The following line will load a local backup copy of pmifschema.xsd if the previous instruction return FALSE // it was tested by me and works fine $schema = $schema ? $schema : file_get_contents("http://www.scienze.univaq.it/Zallocco.Samuel/pmifschema.xsd"); if ($schema) { $dom_model = DOMDocument::loadXML($model); if ($dom_model) { 
			    // the instruction that fail is the following one:

    echo '\n\nCaught exception: ',  $e->getMessage(), "\n";
} echo "\n\n"; ?> __________________________________________________________________________ As you can see running the code, the local invocation of the method validate_pmif_from_xml_schema produce the correct response but when called via the PEAR:SOAP protocol it will fail with an invalid HTTP Response. I have no idea about the source of the problem!! Can you help me in some way?? Thank you.
