Obtaining the WSDL for an SCA component offering
a Service as a Web service

SCA components that expose a Web service interface
(i.e. have an @binding.soap annotation) will return their WSDL
definition in response to an HTTP request with a get parameter of
“wsdl”. The usual way to obtain this is with “?wsdl” on the end of
a URL. The example below uses file_get_contents() to obtain WSDL from a
service and writes it to a temporary file before then obtaining a
proxy for the service in the usual way. You could of course also
obtain the WSDL in a browser, or by some other means, and save the
file yourself.

<?php
$wsdl = file_get_contents('http://www.example.com/Services/Example.php?wsdl');
file_put_contents("service.wsdl",$wsdl); //write the wsdl to a file
$service = SCA::getService('service.wsdl'); 
?>

NOTE: If the wsdl requires imported xsds, these
will need to be fetched separately.
