Compisite Bean Complex Type

[Sivakumar Jagadeesan]

Hi All:

I am getting a NullPointerException when invoking a webservice using a 
JavaClient.

Service Interface is

public boolean uploadFile(
                DataHandler dataHandler,
                MetadataBean metadataBean,
                FolderBean folderBean);
MetadataBean has a another bean (as a composite) PublicationMetaConf.

This is my wsdd file

<deployment xmlns="http://xml.apache.org/axis/wsdd/";
   xmlns:java="http://xml.apache.org/axis/wsdd/providers/java";
   xmlns:schema="http://www.w3.org/2001/XMLSchema";
   xmlns:au="AutoUploaderService">
   <service name="AutoUploaderService" provider="java:RPC">
       <namespace>AutoUploaderService</namespace>
       <parameter name="className" 
value="cat.vce.autoUpload.server.service.AutoUploaderServiceImpl"/>
       <parameter name="allowedMethods" value="*"/>
       <typeMapping 
deserializer="org.apache.axis.encoding.ser.JAFDataHandlerDeserializerFactory"
           languageSpecificType="java:javax.activation.DataHandler" 
qname="au:DataHandler"
           
serializer="org.apache.axis.encoding.ser.JAFDataHandlerSerializerFactory"
           encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";
           />
       <beanMapping qname="au:PublicationMetaConf" 
languageSpecificType="java:cat.vce.autoUpload.server.conf.PublicationMetaConf"/>
       <beanMapping qname="au:MetadataBean" 
languageSpecificType="java:cat.vce.autoUpload.server.bean.MetadataBean"/>
       <beanMapping qname="au:FolderBean" 
languageSpecificType="java:cat.vce.autoUpload.server.bean.FolderBean"/>
   </service>
</deployment>

I have two questions

1) When I make a call using Java client I am getting an NullPointerException

2) I am not able to generate Client side code using WSDL2Java. I am getting 
this error

    [java] java.io.IOException: Type {AutoUploaderService}DataHandler is 
referenced but not defined

It would be great is someone could help me.
