DII unexpected encoding style with SharePoint Web Service

Question

I am trying to call a dynamic sharepoint web service in Java using DII (Dynamic Invocation Interface)
but I kept getting error:unexpected encoding style: after the invoke expected=http://schemas.xmlsoap.org/soap/encoding/, actual=
I am trying to call web service - GetWebCollection()
String endPoint="http://%SPSERVER/_vti_bin/Webs.asmx";
String nameSpaceUri = "xmlns:xsi";
String serviceName = "Webs";
String porttype="WebsSoap";
String NS_XSD = "http://www.w3.org/2001/XMLSchema";
ServiceFactory factory =
ServiceFactory.newInstance();
Service service =factory.createService(new QName(serviceName));
QName qport = new QName(porttype);
hpsharepoint.Webs webs = new hpsharepoint.Webs_Impl();
Call call = (Call) webs.createCall(qport);
call.setProperty(call.USERNAME_PROPERTY,kuser);
call.setProperty(call.PASSWORD_PROPERTY,password);
call.setProperty(Call.ENCODINGSTYLE_URI_PROPERTY, "http://schemas.xmlsoap.org/soap/encoding/");
call.setProperty(Call.SOAPACTION_USE_PROPERTY,
new Boolean(true));
call.setProperty(Call.SOAPACTION_URI_PROPERTY,"http://schemas.microsoft.com/sharepoint/soap/GetWebCollection");
call.setTargetEndpointAddress(endPoint);
call.setOperationName(
new QName(nameSpaceUri,"GetWebCollection"));
String[] params = {};
NodeList list=(NodeList)call.invoke(params);

This is the soap 1.1

Jose,
When you work with Web Services, the common development flow is as follow:
1) develop your service endpoint. You can start from JAVA code or PL/SQL package (bottom-up) or from a WSDL (top-down). In your case, you need to start from the Store Procedures.
2) deploy your service endpoint. As the result of the deployment step, you will have a WSDL available on your application server, that advertise the service interface.
3) generate the static client proxy from the WSDL (service contract).
4) invoke the service using the proxy from step 3 or use dynamic invocation APIs to make direct call, without to use a static proxy.
Bypassing step 3) usually requires a dipper understanding of SOAP linguana, so it's not the easiest way to get started.
Based on the statement you made, it looks like you are starting from step 3)
From the error message, it seams that you are trying to invoke a Web service that was deployed using 'literal' encoding (either document/literal or RPC/literal) with a client generated for RPC-encoded message format. In the JDeveloper Wizard, you have an option to change the message format to RPC/Encoded.
Hope this helps,
