Jax-rpc nested complextype array items ignored

[Alex Giovi]

I created a web service with jax-rpc 1.1 for a QCM. The main class is defined as:
   

  public class QCM_WebService  implements Serializable{
          public void fillQcm (QCMUserResponse [] userResponse) {

         }
     }

Class QCMUserResponse:    

 class QCMUserResponse implements Serializable{
         private int questionID;
        private QcmResponse [] qcmResponseList;    
   }

Class QcmResponse:

  class QcmResponse implements Serializable{

          private int responseID;
         private String response;
    }

This is an example of SoapUI request generated by the WSDL of this service:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
   xmlns:ws="http://org.example" xmlns:qcm="http://com.Test">
  <soapenv:Header/>
 <soapenv:Body>
  <ws:fillQcm>
     <!--Zero or more repetitions:-->
     <ws:userResponse>
        <qcm:questionID>14</qcm:questionID>
        <!--1 or more repetitions:-->
        <qcm:qcmResponseList>
           <qcm:responseID>1</qcm:responseID>
           <qcm:response>true</qcm:response>
        </qcm:qcmResponseList>
        <qcm:qcmResponseList>
           <qcm:responseID>2</qcm:responseID>
           <qcm:response>false</qcm:response>
        </qcm:qcmResponseList>
            <qcm:qcmResponseList>
           <qcm:responseID>3</qcm:responseID>
           <qcm:response>false</qcm:response>
        </qcm:qcmResponseList>
     </ws:userResponse>
    </ws:fillQcm>
 </soapenv:Body>
</soapenv:Envelope>

When I try to test this service, I've got in my Java class an array of QCMUserResponse, this array contains the questionID value and an array of QcmResponse which always has one item: (in the case above, the last one with response id equal to 3), the others item that I passed as input argument are ignored.

Any ideas? Is it possible that jax-rpc doesn't support nested arrays?
