Unabel to hit the webservice usind DII approach

[jagan raja]

Hi All,

I am trying to invoke webservices through DII approach and followed some samples which are provided.

Most of the samples provided passes String datatype as input and recieves the same datatype as output.

In my case I want to pass a request bean object and get back a response bean object.

I was able to invoke the wsdl using the classes provided in SAAJ api but not using rpc.Call class.

          QName serviceQN = new QName(namespace, serviceName);
			ServiceFactory serviceFactory = ServiceFactory.newInstance();
			Service service = serviceFactory.createService(serviceQN);
			QName portQN = new QName(namespace, portName);
			QName operationQN = new QName(namespace, operationName);
			//QName returnQN = new QName(namespace, "GetDefaultRechargeValuesOutput");
			
			
			Call call = (Call)service.createCall();
 			
			call.setProperty(javax.xml.rpc.Call.SOAPACTION_USE_PROPERTY, new Boolean(true));
			call.setProperty(Call.SOAPACTION_URI_PROPERTY, "");
			call.setProperty(Call.OPERATION_STYLE_PROPERTY, "document");
			call.setProperty(Call.ENCODINGSTYLE_URI_PROPERTY, "http://schemas.xmlsoap.org/soap/encoding/");
			
			call.setTargetEndpointAddress(
			"http://ip:port/sample/Services/Proxy_Services/sample?wsdl");
			call.removeAllParameters();
			call.setPortTypeName(portQN);
			call.setOperationName(operationQN);
			
			QName nmspcin=new QName(namespace, "SampleInput");
			QName nmspcout=new QName(namespace, "SampleOutput");
			
			SampleInput req=new SampleInput();
			req.setValue("invoke");
			call.addParameter("SampleInput",nmspcin,com.sample.SampleInput.class,
                    ParameterMode.IN);
            call.setReturnType(nmspcout);
			
			
			Object[] inParams = new Object[] {req};
											 
			SampleOutput res=(SampleOutput)call.invoke(inParams);

SampleInput and SampleOutput are the request response classes which has got only the getters and setters. When using the SAAJ classes these classes were not used.

When I execute the above snippet I faced a error as below,

javax.xml.rpc.JAXRPCException: failed to invoke operation 'getDefaultRechargeValues' due to an error in the soap layer (SAAJ); nested exception is: Message[ failed to serialize class com.sample.SampleInputweblogic.xml.schema.binding.SerializationException: mapping lookup failure. class=class com.sample.SampleInput class context=TypedClassContext{schemaType=['http://www.sample.com/sample/workflow/samplereqcs']:SampleInput}]StackTrace[

I am not sure where I have gone wrong.

Thanks
