Java-XmlMapping

[tasneem <ta...@verchaska.com>]

I am trying to run a Client example on Axis ....
But i have a problem when the return type is a String the service works fine.
but when i am trying to return a Hashtable instead of a string i get a null pointer .....

I guess there's some problem in my Java and Xml Type mapping 

the deploy.wsdd which is formed Wsdl2java command looks something like this 

<deployment
    xmlns="http://xml.apache.org/axis/wsdd/"
    xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">

  <!-- Services from RandDService WSDL service -->

  <service name="RandD" provider="java:RPC">
      <parameter name="className" value="com.vtech.gcf.control.ws2.RandDSoapBindingSkeleton"/>
      <parameter name="allowedMethods" value="*"/>
      <parameter name="scope" value="Session"/>

      <typeMapping
        xmlns:ns="http://util.java"
        qname="ns:Dictionary"
        type="java:java.util.Dictionary"
        serializer="org.apache.axis.encoding.ser.BeanSerializerFactory"
        deserializer="org.apache.axis.encoding.ser.BeanDeserializerFactory"
        encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
      />
      <typeMapping
        xmlns:ns="http://util.java"
        qname="ns:Hashtable"
        type="java:java.util.Hashtable"
        serializer="org.apache.axis.encoding.ser.BeanSerializerFactory"
        deserializer="org.apache.axis.encoding.ser.BeanDeserializerFactory"
        encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
      />
  </service>
</deployment>

where it is making this mapping for the hashtable now what should i do .......please help .....

Thanks In Advance
