Hi Christophe,
According to your suggestion, I took out the inherited fileds. and I
checked my PolymorphStub.java, it does include both Shape and Square,
see below:
public PolymorphStub(javax.xml.rpc.Service service) throws
org.apache.axis.AxisFault {
if (service == null) {
super.service = new org.apache.axis.client.Service();
} else {
super.service = service;
}
java.lang.Class cls;
javax.xml.namespace.QName qName;
java.lang.Class beansf =
org.apache.axis.encoding.ser.BeanSerializerFactory.class;
java.lang.Class beandf =
org.apache.axis.encoding.ser.BeanDeserializerFactory.class;
java.lang.Class enumsf =
org.apache.axis.encoding.ser.EnumSerializerFactory.class;
java.lang.Class enumdf =
org.apache.axis.encoding.ser.EnumDeserializerFactory.class;
java.lang.Class arraysf =
org.apache.axis.encoding.ser.ArraySerializerFactory.class;
java.lang.Class arraydf =
org.apache.axis.encoding.ser.ArrayDeserializerFactory.class;
java.lang.Class simplesf =
org.apache.axis.encoding.ser.SimpleSerializerFactory.class;
java.lang.Class simpledf =
org.apache.axis.encoding.ser.SimpleDeserializerFactory.class;
qName = new javax.xml.namespace.QName("urn:copy", "Shape");
cachedSerQNames.add(qName);
cls = copy.Shape.class;
cachedSerClasses.add(cls);
cachedSerFactories.add(beansf);
cachedDeserFactories.add(beandf);
qName = new javax.xml.namespace.QName("urn:copy", "Square");
cachedSerQNames.add(qName);
cls = copy.Square.class;
cachedSerClasses.add(cls);
cachedSerFactories.add(beansf);
cachedDeserFactories.add(beandf);
}
But when I run it, it still throw following:
SEVERE: Exception:

I saw your first reply mail, you have abstract="true", so I add this to
.wsdl, see below:
<complexType abstract="true" name="Shape">
<sequence>
<element name="name" type="xsd:string" minOccurs="0" maxOccurs="1"
nillable="true"/>
<element name="sides" type="xsd:int" minOccurs="1" maxOccurs="1"/>
</sequence>
</complexType>
<complexType name="Square">
<complexContent>
<extension base="ns:Shape">
<sequence>
<element name="size" type="xsd:int" minOccurs="1" maxOccurs="1"/>
</sequence>
</extension>
</complexContent>
</complexType>
This time after I run it, it throws different exception:
SEVERE: Exception:
org.xml.sax.SAXException: Unable to create JavaBean of type copy.Shape.
Missing
default constructor? Error was: java.lang.InstantiationException.

I checked both Square.java and Shape.java, they do have default
constructor, any idea?
I don't know how to run tcpmonitor because every time my client open a
random port, and I have no idea which port should I specify to
listening when using tcpmonitor, so I use different tools to get the
packet sending from the server, here are the sever reply xml:
HTTP/1.1 200 OK
Server: gSOAP/2.7
Content-Type: text/xml; charset=utf-8
Content-Length: 538

<size>40</size>
</out>
</ns:polytestResponse></SOAP-ENV:Body></SOAP-ENV:Envelope>
Do you have any idea, why the axis still try to build "Shape" object
instead of "Square"? and why it complain Missing default constructor at
second time?
Thanks,
Georgia

I don't think you have to declare the inherited fields sides and size in
the
derived type Square.
Check if you have a serializer declared for Square in your generated
stub.
public XxxxxStub(javax.xml.rpc.Service service) throws
org.apache.axis.AxisFault {
if (service == null) {
super.service = new org.apache.axis.client.Service();
} else {
super.service = service;
}
...
qName = new javax.xml.namespace.QName("...", "Square");
cachedSerQNames.add(qName);
cls = xxx.Square.class;
cachedSerClasses.add(cls);
cachedSerFactories.add(beansf);
cachedDeserFactories.add(beandf);
....
}
Then check with the tcpmonitor what was send back by the server.
Christophe
