Serialization issue

[I.V.Rajesh]

Hi,
        I have deployed my service in Axis engine. I have written
serializer and deserializer for the class ObjectName which is used for
invoking the method in RemoteMBeanServerImpl.  This is shown  below. But
when i try to invoke the method it throws SAXException.

MY  wsdd file conmtains:

<service name="SoapAdaptorService" provider="java:RPC">
    <parameter name="className"
value="com.adventnet.adaptors.soap.RemoteMBeanServerImpl" />
    <parameter name="allowedMethods" value="*" />
    <typeMapping xmlns:ns="http://soapinterop.org/xsd";
            qname="ns:ObjectName"
            type="java:javax.management.ObjectName"
            serializer="org.apache.axis.encoding.SerializerFactory"
            deserializer="org.apache.axis.encoding.DeserializerFactory"
            encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"; />

   </service>

The Exception content :
SAXEXCEPTION: Deseralizing parameter "arg0": could not find deseralizer
for type {http://www.w3.org/2001/XMLSchema}anyType

I have given a print in my serialize file (i.e ObjectNameSer.java). But
it was not called.
Please may i know where i am going wrong?.

Thanks,
Rajesh I.V
