Hi bill,
Thanks for the input. 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] => ) )

Client file:

require_once("SOAP/Client.php");
$client = new SOAP_Client('http://trurl.dom.washington.edu/testsite/SOAP/tests/pearsoap-hello-server.php');
$params = array('inmessage'=>'World'); $options = array('trace'=>'true','timeout'=>5);
$response = $client->call('helloWorld',$params,array('namespace'=>'urn:helloworld'),$options);
try like this:
$client->call('helloWorld',$params,$options);
Not sure where 'urn:helloworld' is supposed to go, but I think it should work without it.
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>'; }
