The QName is not the name of the class. As I replied to you yesterday, a QName is a qualified name (in XML) that has two parts. The first part is a namespace (a URI), the second part is the local name ("Session"). In your particular case, the QName refers to the XML type of your return value. The XML type information is specified in the WSDL (and the WSDD if the service is built with Axis). For example, (assuming that you are using RPC/encoded, which is the default in Axis) the WSDL would define your return message as:
<wsdl:message name="SessionResponse>
<wsdl:part name="session" type="impl:Session"/>
</wsdl:message>
In this case, the type QName is "impl"Session". (The structure of the "impl:Session" type should be defined in the <wsdl:types> section using XML Schema.) The "impl" prefix refers to your WSDL targetNamespace. Given your package name, I would guess that the namespace URI is "
http://session.dis.disney", but I suggest you verify that. <wsdl:part name="session" type="impl:Session"/>
</wsdl:message>
If you are using RPC/encoded (the default) then the XML type information is also specified on the wire. For example, your return message will include something like this:
<ns1:Return xmlns:ns1="http://session.dis.disney">
<session xsi:type="ns1:Session">[session-data]</Session>
</ns1:Return>
<session xsi:type="ns1:Session">[session-data]</Session>
</ns1:Return>
In this example, the XML type is "http://session.dis.disney}Session" (you must map the "ns1" prefix to the actual namespace URI), and your Java QName would be defined like this:
new QName ("http://session.dis.disney", "Session")
See http://java.sun.com/webservices/docs/1.6/api/javax/xml/namespace/QName.html)
for more information about the Java QName class.
Note -- you cannot use the JWS deployment method if you are returning a ValueType rather than a primitive type. You must use the WSDD method.

Could someone tell me what are the QName arguments to the
BeanSerializerFactory and BeanDeserializerFactory constructors?
Do I instantiate QName with the name of my class:
"disney.dis.session.PlayerSession "
I tried doing this
QName qName = new QName("disney.dis.session.PlayerSession");
BeanSerializerFactory bsf =
new BeanSerializerFactory(cl, qName);
BeanDeserializerFactory bdf =
new BeanDeserializerFactory(cl, qName);
call.registerTypeMapping(cl, qName, bsf, bdf);
before my "invoke" call. I'm getting the same error.
- Exception:
org.xml.sax.SAXException: Deserializing parameter 'getSessionReturn':
could not find deserializer for type {disney.dis}PlayerSession
at
org.apache.axis.message.RPCHandler.onStartChild (RPCHandler.java:277)
at
org.apache.axis.encoding.DeserializationContext.startElement(DeserializationContext.java:1035)
I don't know if I'm on the right track or not. Any ideas anyone?
Many thanks.
