pubilc A getMessage()
			

			{
			

			B b = new B();
			

			b.setName("test");
			

			return b;
			

			}
			

			

			And here's my client
			

			

			serializer = new BeanSerializer();
			

			QName dataQName = new QName("urn:A","A");
			

			registry.mapTypes(Constants.NS_URI_SOAP_ENC,dataQName,A.class, serializer, serializer);
			

			

			dataQName = new QName("urn:B","B");
			

			registry.mapTypes(Constants.NS_URI_SOAP_ENC,dataQName,B.class, serializer, serializer);
			

			

			Call call = new Call();
			

			call.setSOAPMappingRegistry(registry);
			

			call.setTargetObjectURI("urn:server");
			

			call.setMethodName("getMessage");
			

			call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);
			

			

			Response response =  call.invoke(url,"");
			

			A a = (A) response.getParameter().getValue();
			

			B b = (B) a;
			

			

			System.out.println(b.getName());
			

			

			END....
			

			

			Now please have a look at A and B
			

			

			

			public interface A
			

			{
			

			public String getName();
			

			public void setName();
			

			}
			

			

			public class B implements A
			

			{
			

			private String name;
			

			public String getName()
			

			{
			

			return this.name;
			

			}
			

			

			public void setName(String name)
			

			{
			

			this.name = name;
			

			}
			

			

			}
