Building a Test Step from a WSDL

I should have posted a follow up here to explain that I had accomplished it. Here is the code I used:

            WsdlProject project = new WsdlProject();
            project.setName("Test");
            WsdlInterface iface = WsdlInterfaceFactory.importWsdl(project, "MyWsdlPath", true)[0];
            String host = "MyHostPath";
            String endpoint = iface.getEndpoints()[0].replaceAll("http.*?//.*?/",host);
            iface.changeEndpoint(iface.getEndpoints()[0],endpoint);
            WsdlOperation operation = (WsdlOperation) iface.getOperationByName("OperationIamBuilding");
            WsdlTestSuite TS = project.addNewTestSuite("Test");
            TS.setName("Test");
            TestStepConfig TStepC = WsdlTestRequestStepFactory.createConfig(operation, "Test");
            WsdlTestCase TC = TS.addNewTestCase("Test");
            WsdlTestStep TStep = TC.addTestStep(TStepC);
            String rawRequest = TStep.getPropertyValue("Request");
            TStep.setPropertyValue("Username", properties.get("username").trim());
            TStep.setPropertyValue("Password", properties.get("password").trim());
            NodeList nodes = XmlUtils.parseXml(operation.getRequestAt(0).getRequestContent()).getChildNodes();
            String XML = XmlUtils.prettyPrintXml(XmlUtils.createXmlObject(nodes.item(0).getParentNode()));
            XML = XML.replaceAll( "(?s)<!--.*?-->","");
//Data parsing would go here.
            TStep.setPropertyValue("Request", XML);
            project.saveAs("Test.xml");

(Again, this is in Java, not SoapUI itself. I am building something to build SoapUI project files). This snippet will essentially build a SoapUI request for the single operation currently.
