If you installed WSF/PHP with your php server, you can try simple test php pages to access job submission service. Please make sure the SOAP body part should follow the style defined in the WSDL file. In my case, I could get the XML string from my SOAP monitor easily. However, you can simply download my example and use it as your template.
