Hi all,

I've got this exception on my server after a SOAP call :

Here's the code which causes the error (the data is transfered, it crashes during deserialization on server):

// SOAP call URL URL url = new URL( "http://"; + sName + ":" + sPort + "/axis/services/Gothmog"); Server.debugString( "SendArray to site " + dstSite + ", URL: " + url); // Fill array of IntMsg int nbm = imV.size(); Object[] ot = imV.toArray(); IntMsg[] imt = new IntMsg[nbm]; for (int k = 0; k < nbm; k++) { imt[k] = (IntMsg) ot[k]; } Server.debugString( "SendArray: " + dstSite + ", " + nbm + " messages");

try { // Configure SOAP call Service service = new Service(); Call call = (Call) service.createCall(); call.setTimeout(Integer.valueOf("600000")); // 10 min timeout // Map IntMsg QName qn1 = new QName("urn:BeanService", "IntMsg"); call.registerTypeMapping( IntMsg.class, qn1, new org.apache.axis.encoding.ser.BeanSerializerFactory( IntMsg.class, qn1), new org.apache.axis.encoding.ser.BeanDeserializerFactory( IntMsg.class, qn1)); // Map IntMsg array QName qn2 = new QName("urn:BeanService", "IntMsgArray"); call.registerTypeMapping( IntMsg[].class, qn2, new org.apache.axis.encoding.ser.ArraySerializerFactory(), new org .apache .axis .encoding .ser .ArrayDeserializerFactory()); // SOAP call to send the IntMsg array call.setTargetEndpointAddress(url); call.setOperationName(new QName("IntMsgArray", "receiveArray")); call.addParameter("imt", qn2, ParameterMode.IN); call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING); String result = (String) call.invoke(new Object[] { imt });

///////////////////////////////////////////////////////////////////////////////////////////////

And my deployment descriptor:

<deployment xmlns="http://xml.apache.org/axis/wsdd/";
           xmlns:java="http://xml.apache.org/axis/wsdd/providers/java";>
<service name="Gothmog" provider="java:RPC">
 <parameter name="className" value="gothmog.Server"/>
 <parameter name="allowedMethods" value="*"/>

 <typeMapping
   qname="myNS:IntMsg"
   type="java:gothmog.IntMsg"
     xmlns:myNS="urn:BeanService"
   encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";
   serializer="org.apache.axis.encoding.ser.BeanSerializerFactory"
     deserializer="org.apache.axis.encoding.ser.BeanDeserializerFactory"
     />
 <typeMapping
   qname="myNS:IntMsgArray"
   type="java:gothmog.IntMsg[]"
     xmlns:myNS="urn:BeanService"
   encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";
   serializer="org.apache.axis.encoding.ser.ArraySerializerFactory"
     deserializer="org.apache.axis.encoding.ser.ArrayDeserializerFactory"
     />
</service>
</deployment>

The IntMsg class is a bean. Well handled by Bean(De)Serializer...

What did I miss ?

Thanks in advance,
