Typically, you would be using some SOAP client API code in the browser (JavaScript,AJAX, Perl, PHP, Java, some .NET language, etc.) to make your webservices call.
In addition to the SOAP Developer’s Guide that Rob recommended, you might also need to read up on how your web programming language of choice makes SOAP calls. Ba-zillions of books on that over-hyped topic.
If you just want a quick way to test web services provided by IS, download a free copy of CrossCheck Network’s SOAP Sonar personal edition, point it at a WSDL and execute the test cases it generates.
