Hi everybody,
I have a method in my service which return an ArrayList. In the SoapMonitor I see that: 

<?xml version="1.0" encoding="UTF-8"?>

   </multiRef>
 </soapenv:Body>
</soapenv:Envelope>

But in the client I have a NullPointerException why?

I use to deploy my servie the next deploy.wsdd:

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

   <service name="RmiSoapWorkSession" provider="java:RPC">
       <requestFlow>
           <handler type="session"/>
           <handler type="soapmonitor"/>
       </requestFlow>
       <responseFlow>
           <handler type="session"/>
           <handler type="soapmonitor"/>
       </responseFlow>

       <parameter name="className" 
value="openwfe.org.worklist.ws.impl.RmiSoapWorkSession"/>
       <parameter name="allowedMethods" value="Hello authentify 
countWorkItems getStoreNames findFlowInstance getHeaders get getAndLock 
release save forward getLaunchables launch delegate 
getParticipantsForDelegation delegateToParticipant checkPermission"/>

       <parameter name="scope" value="Session"/>

       <beanMapping qname="ns:InFlowWorkItem" 
xmlns:ns="urn:BeanService" 
languageSpecificType="java:openwfe.org.engine.workitem.InFlowWorkItem"/>
       <beanMapping qname="ns:FlowExpressionId"

languageSpecificType="java:openwfe.org.engine.expressions.FlowExpressionId"/>
       <beanMapping qname="ns:LaunchItem" xmlns:ns="urn:BeanService"

       <beanMapping qname="ns:Header" xmlns:ns="urn:BeanService"

       <beanMapping qname="ns:StringMapAttribute" 
xmlns:ns="urn:BeanService" 
languageSpecificType="java:openwfe.org.engine.workitem.StringMapAttribute"/>
       <beanMapping qname="ns:StringAttribute" 
xmlns:ns="urn:BeanService" 
languageSpecificType="java:openwfe.org.engine.workitem.StringAttribute"/>
       <beanMapping qname="ns:Launchable" xmlns:ns="urn:BeanService" 
languageSpecificType="java:openwfe.org.worklist.Launchable"/>
       <beanMapping qname="ns:HistoryItem" xmlns:ns="urn:BeanService" 
languageSpecificType="java:openwfe.org.engine.workitem.HistoryItem"/>
       <beanMapping qname="ns:Subject" xmlns:ns="urn:BeanService" 
languageSpecificType="java:javax.security.auth.Subject"/>
       <arrayMapping qname="ns:ArrayList" xmlns:ns="urn:BeanService" 
languageSpecificType="java:java.util.ArrayList" 
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>

   </service>
</deployment>

In my client I have the next registrerTypeMapping:
call.registerTypeMapping(Launchable.class, qnLaunchable,
                   new org.apache.axis.encoding.ser.BeanSerializerFactory(
                           Launchable.class, qnLaunchable),

                   new 
org.apache.axis.encoding.ser.BeanDeserializerFactory(

                           Launchable.class, qnLaunchable));
call.registerTypeMapping(
                           ArrayList.class,
                           qnArrayList,

                           new 
org.apache.axis.encoding.ser.ArraySerializerFactory(),
                           new 
org.apache.axis.encoding.ser.ArrayDeserializerFactory());


What is wrong?

Thanks,
Christelle
