Serialization error while returning Value Object from Web Service

Question

Hi
I have developed a sample Web Service (RPC based), it returns Customer Value Object
when client calls getCustomer method.
I have written a Client (attached the client source code) to invoke the web service
when the client invokes the Web Service it throws an Exception , the Exception
Exception in thread "main" serialization error: no serializer is registered for
(null, {java:customer}Customer)
at com.sun.xml.rpc.encoding.DynamicInternalTypeMappingRegistry.getSerializer(DynamicInternalTypeMappingRegistry.java:62)
at com.sun.xml.rpc.encoding.soap.SOAPResponseSerializer.initialize(SOAPResponseSerializer.java:72)
at com.sun.xml.rpc.encoding.ReferenceableSerializerImpl.initialize(ReferenceableSerializerImpl.java:47)
at com.sun.xml.rpc.client.dii.BasicCall.createRpcResponseSerializer(BasicCall.java:382)
at com.sun.xml.rpc.client.dii.BasicCall.getResponseDeserializer(BasicCall.java:364)
at com.sun.xml.rpc.client.dii.BasicCall.invoke(BasicCall.java:259)
at ClientwithWSDL.main(ClientwithWSDL.java:63)
CAUSE:
no serializer is registered for (null, {java:customer}Customer)

at com.sun.xml.rpc.encoding.InternalTypeMappingRegistryImpl.getSerializer(InternalTypeMappingRegistryImpl.java:287)

If someone can help me to fix the issue, it will be great.

Answer 1

I guess, this is because the RI client is not finding the
codec to ser/deser your Value Object. You need to register
the codec in the type mapping registry before you invoke
the web service method.
Here is a sample:
Service service = factory.createService( serviceName );
TypeMappingRegistry registry = service.getTypeMappingRegistry();
TypeMapping mapping = registry.getTypeMapping(
SOAPConstants.URI_NS_SOAP_ENCODING );
mapping.register( SOAPStruct.class,
new QName( "http://soapinterop.org/xsd", "SOAPStruct" ),
new SOAPStructCodec(),
new SOAPStructCodec() );
BTW, you can do the same exact thing on the client by using
WLS impl of JAX-RPC. Is there a reason for using RI on the
client side?

Hi Manoj,
Thanks for your information, Yes, my client is Sun's JAX-RPC based, but the Server
Implementation is done using Weblogic 7.0. When I invoke the Client without WSDL.
It works fine without any problem. But when I invoke the webservice using WSDL,
I am getting this problem.
Here is my Client Code :
* This class demonstrates a java client invoking a WebService.
import java.net.URL;
import javax.xml.rpc.ServiceFactory;
import javax.xml.rpc.Service;
import javax.xml.rpc.Call;
import javax.xml.rpc.ParameterMode;
import javax.xml.namespace.QName;
import customer.Customer;
public class ClientwithWSDL {
private static String qnameService = "CustomerService";
private static String qnamePort = "CustomerServicePort";
private static String BODY_NAMESPACE_VALUE =
"http://jeyakumar_3957:7001/Customer";
private static String ENCODING_STYLE_PROPERTY =
"javax.xml.rpc.encodingstyle.namespace.uri";
private static String NS_XSD =
"http://www.w3.org/2001/XMLSchema";
private static String URI_ENCODING =
"http://schemas.xmlsoap.org/soap/encoding/";
private static String method="getCustomer";
private static String endpoint="http://jeyakumar_3957:7001/webservice/CustomerService?WSDL";
public static void main(String[] args) throws Exception {
// create service factory
ServiceFactory factory = ServiceFactory.newInstance();
// define qnames
QName serviceName =new QName(BODY_NAMESPACE_VALUE, qnameService);
QName portName = new QName(BODY_NAMESPACE_VALUE, qnamePort);
QName operationName = new QName("",method);
URL wsdlLocation = new URL(endpoint);
// create service
Service service = factory.createService(wsdlLocation, serviceName);
// create call
Call call = service.createCall(portName, operationName);
// invoke the remote web service
Customer result = (Customer) call.invoke(new Object[0]);
System.out.println("\n");
System.out.println(result);
