Hi, All

Anyone could give me some help, thanks a lot:

The web-service.xml file:
<?xml version="1.0" encoding="UTF-8"?>

<deployment
xmlns="http://xml.apache.org/axis/wsdd/"
targetNamespace="http://net.jboss.org/hello"
xmlns:hello="http://net.jboss.org/hello"
xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
<!-- this is an extension to the Axis deployment descriptor which allows to
specify the naming environment for the deployed ws logic -->
















<typeMapping
xmlns:ns="SoapDriver"
qname="MmmscObject"
type="java:uk.generic.MmscObject"
serializer="org.apache.axis.encoding.ser.BeanSerializerFactory"
deserializer="org.apache.axis.encoding.ser.BeanDeserializerFactory"
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
/>
<typeMapping
xmlns:ns="SoapDriver"
qname="MessageResponseCore"
type="java:uk.dto.MessageResponseCore"
serializer="org.apache.axis.encoding.ser.BeanSerializerFactory"
deserializer="org.apache.axis.encoding.ser.BeanDeserializerFactory"
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
/>
<typeMapping
xmlns:ns="SoapDriver"
qname="MessageResponse"
type="java:uk.dto.MessageResponse"
serializer="org.apache.axis.encoding.ser.BeanSerializerFactory"
deserializer="org.apache.axis.encoding.ser.BeanDeserializerFactory"
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
/>



The Client program:
...
QName mmscQName = new QName("SoapDriver", "MmscObject");
call.registerTypeMapping(MmscObject.class, mmscQName, new BeanSerializerFactory(MmscObject.class,mmscQName),
new BeanDeserializerFactory(MmscObject.class,mmscQName));

QName mrcQName = new QName("SoapDriver", "MessageResponseCore");
call.registerTypeMapping(MessageResponseCore.class, mrcQName, new BeanSerializerFactory(MessageResponseCore.class,mrcQName),
new BeanDeserializerFactory(MessageResponseCore.class,mrcQName));

QName mrQName = new QName("SoapDriver", "MessageResponse");
tm.register(MessageResponse.class, mrQName, new BeanSerializerFactory(MessageResponse.class,mrQName), new
BeanDeserializerFactory(MessageResponse.class,mrQName));
...

call.setReturnType(org.apache.axis.Constants.XSD_ANY);
rpdto = (MessageResponse) call.invoke( new Object[] { para1, .., para11} );
------------------------------------------------------------------------------------->
where MessageResponse extends MmscObject, and conclude MessageResponseCore, they are all serializable.

using TCPMON, I can capture both the request and response, but got error:------------------------------------------------------------------>
