This prootocol reminds me a bit of OSC, which I've used before for passing control data for audio applications over networks. I've found a 'basic' tutorial online that gets one started writing a 'hello world' kind of program with a SOAP server and client, but the tutorial has problems, the code seems to malfunction. I'm going to paste in the files as I found them online, perhaps someone can help me to figure out what is going wrong. by the way, the tutorial I'm referring to is at the following URL: http://evolt.org/article/The_PEAR_SOAP_Implementation/21/49993/index.html The tutorial says that if I call the client file from my browser, I should get 'hello world' to show up. This doesn't happen. I get some strange error messages instead, especially after adding the error tracking code that you suggested (Thanks for that, by the way!). Here's the errors I get, printed as requested from the client file below: (apologies for the crappy linebreaks and tabbing) Printed return from client file: ********************** Object message: method '{urn:helloworld}helloWorld' not defined in service user info: Array get wire Here's some user info stdClass Object ( [file] => /usr/local/php/lib/php/SOAP/Fault.php [line] => 49 [function] => pear_error [class] => pear_error [type] => :: [args] => Array ( [0] => method '{urn:helloworld}helloWorld' not defined in service [1] => Server [2] => [3] => [4] => ) ) Here's some user info stdClass Object ( [file] => /usr/local/php/lib/php/SOAP/Base.php [line] => 199 [function] => soap_fault [class] => soap_fault [type] => -> [args] => Array ( [0] => method '{urn:helloworld}helloWorld' not defined in service [1] => Server [2] => [3] => [4] => [5] => ) ) Here's some user info stdClass Object ( [file] => /usr/local/php/lib/php/SOAP/Server.php [line] => 377 [function] => _raisesoapfault [class] => soap_server [type] => -> [args] => Array ( [0] => method '{urn:helloworld}helloWorld' not defined in service [1] => [2] => [3] => Server ) ) Here's some user info stdClass Object ( [file] => /usr/local/php/lib/php/SOAP/Server.php [line] => 168 [function] => parserequest [class] => soap_server [type] => -> [args] => Array ( [0] => World [1] => ) ) Here's some user info stdClass Object ( [file] => /Users/cewing/phpstuff/CMEtests/SOAP/tests/pearsoap-hello-server.php [line] => 33 [function] => service [class] => soap_server [type] => -> [args] => Array ( [0] => World ) ) ********************** Client file: ********************** <?php require_once("SOAP/Client.php"); $client = new SOAP_Client('http://trurl.dom.washington.edu/testsite/SOAP/tests/pearsoap-he llo-server.php'); $params = array('inmessage'=>'World'); $options = array('trace'=>'true','timeout'=>5); $response = $client->call('helloWorld',$params,array('namespace'=>'urn:helloworld'),$opt ions); print $response.'<br>'; //Stuff added after this point comes from Bill Moran, Thanks!!!! if (PEAR::isError($response)) { echo 'message: '.$response->getMessage().'<br>'; echo 'user info: '.$response->getUserInfo().'<br>'; echo 'get wire'.$client->__get_wire().'<br>'; } foreach ($response->getUserInfo() as $k=>$v) { echo "Here's some user info<br>"; print_r($v); echo '<p>'; } ?> ********************** Server File: ********************** <?php require_once('SOAP/Server.php'); class SOAP_Hello_Server { var $dispatch_map = array(); function SOAP_Hello_Server() { $this->dispatch_map['helloWorld'] = array('in'=>array('inmessage'=>'string'), 'out'=>array('outmessage'=>'string')); } function helloWorld ($inmessage) { if ($inmessage == '') { $fault = new SOAP_Fault('You must provide a valid string!','12345'); return $fault->message(); } else { return "Hello $inmessage!"; } } } $server = new SOAP_Server(); $soaphelloserver = new SOAP_Hello_Server(); $server->addObjectMap($soaphelloserver,array('namespace'=>'urn:helloworld')) ; $server->service($HTTP_RAW_POST_DATA); exit; ?> ********************** ******************************** Cris Ewing CME and Telehealth Web Services University of Washington School of Medicine Work Phone: (206) 685-9116 Home Phone: (206) 365-3413 E-mail: cewing@u.washington.edu ******************************* On Fri, 27 Feb 2004, Bill Moran wrote: > cristopher pierson ewing wrote: > > Hello, > > > > I'm building a website to provide online Continuing Medical Education > > content to Physicians and Helath Care workers. > > > > Much of the material for my online courses is being stored in a system > > called the DigitalWell, created by the University of Washington.
