Re: Deserialization problem for an inner class

Reply to myself, for people that will have the same troubles :
the InnerBean class should be static

Hello I have no problem for writing Java clients for "normal" beans returned, but, I have a problem with a bean that is an inner class.

So my bean is something like that :
package my.package;
public class FirstClass
{
        ...
        
//my inner class
        public class InnerBean
        {
        ....
        }
        
}

Note that FirstClass is also a a webservice class, with a method that will return an instance of InnerBean.

The wsdd :

<deployment
        name="authentication"
        xmlns="http://xml.apache.org/axis/wsdd/";
        xmlns:java="http://xml.apache.org/axis/wsdd/providers/java";
        xmlns:esis="urn:my.package.FirstClass"
>
        <service name="Authentication" provider="java:RPC">
                <parameter name="className" value="my.package.FirstClass" />
                <parameter name="allowedMethods" value="*" />

                <namespace>urn:my.package.FirstClass</namespace>
<beanMapping qname="myNS:FirstClass"
                        
languageSpecificType="java:my.package.FirstClass$InnerBean" />

Now the client :

I declare as usual all the stuff, except for the return type :

QName qn = new QName("urn:my.package.FirstClass","InnerBean");
call.registerTypeMapping(my.package.FirstClass.InnerBean.class,qn,
new BeanSerializerFactory(my.package.FirstClass.InnerBean.class,qn),
new BeanDeserializerFactory(my.package.FirstClass.InnerBean.class,qn));
call.setReturnType(qn);
FirstClass.InnerBean beanReturned=(FirstClass.InnerBean)call.invoke(objectArray);

The problem is that there are no problems server-side, I can watch the SOAP message that return what i want.
Client-side, I get an exception :
org.xml.sax.SAXException: Unable to create JavaBean of type my.package.FirstClass$InnerBean. Missing default constructor? Error was: java.lang.InstantiationException: my.package.FirstClass$InnerBean.

(and of course, both classes FirstClass and InnerBean have a default constructor).

I don't know where is the problem, in the wsdd, on the client, on the server?
