Custom Serialization

Question

Hello,
In My development I have to make a Web service which shout returns Complex Type.
From Otn as follows
http://otn.oracle.com/tech/webservices/htdocs/samples/serialize/index.html
I found how to do it through editing WSDL/Web.xml file.
But when i Testing my Web service it occures
following
errors:
04/03/15 12:54:04 java.lang.IllegalArgumentException: No Serializer found to serialize a 'java.util.HashMap' using encoding style 'http://schemas.xmlsoap.org/soap/encoding/'.

I am using Jdev 10g preview with Embebded Oc4j Server.
Where should be the Problem?

hi,
I worked with service exposed as a webservice accepting and returning the HashMap as parameter. Its working with me.
I will provide you with the code. go thru it. let me know if you have any queries.
client code
package com.hash.map.service;
import java.util.HashMap;
import javax.xml.rpc.encoding.DeserializerFactory;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.encoding.XMLType;
import org.apache.axis.utils.Options;
import org.apache.axis.encoding.ser.BeanSerializerFactory;
import org.apache.axis.encoding.ser.BeanDeserializerFactory;
import javax.xml.rpc.ParameterMode;
import javax.xml.namespace.QName;
public class HashMapServiceClient
public HashMapServiceClient()
public static void main(String str[])
try{
String endPoint = "http://localhost:8080/axis/servlet/AxisServlet";
Service service = new Service();
Call call = (Call)service.createCall();
call.setTargetEndpointAddress(new java.net.URL(endPoint));
QName qNameIn = new QName("http://util.java","HashMap");
call.addParameter(qNameIn,qNameIn,HashMap.class,ParameterMode.IN);
call.setOperationStyle("rpc");
call.setReturnClass(HashMap.class);
//call.registerTypeMapping(HashMap.class,qNameIn,BeanSerialzerFactory.class,BeanDeserializerFactory.class);
call.setOperationName((new QName("MyHashMapService","getHashMap")));
HashMap hashMap = new HashMap();
hashMap.put("name","Harish");
hashMap.put("age","27");
HashMap map = (HashMap)call.invoke(new Object[] {hashMap});
System.out.println("Name changed-->" + (String)map.get("name"));
System.out.println("Age changed-->" + (String)map.get("age"));
}catch(Exception e)
e.printStackTrace();

<parameter name="className" value="com.hash.map.service.HashMapService"/>

</deployment>
service
package com.hash.map.service;
import java.util.HashMap;
public class HashMapService
public HashMapService()
public HashMap getHashMap(HashMap hashMap)
System.out.println("Service Started");
HashMap map = hashMap;
String strName = (String)map.get("name");
String strAge = (String)map.get("age");
map.put("name","Kiran");
map.put("age","24");
System.out.println("Service Ended");
return map;
