after axis to generate the stub, we got the exception when we call webservice

["kevin.Zh" <ph...@yahoo.com.cn>]

My wsdl schema is following:

- <xs:complexType name="VeridQuestions">
- <xs:sequence>
  <xs:element name="VeridQuestionSetId" type="xs:string" minOccurs="0" /> 
  <xs:element name="VeridQuestion" type="tns:VeridQuestion"
maxOccurs="unbounded" minOccurs="0" /> 
  </xs:sequence>
  </xs:complexType>
- <xs:complexType name="VeridQuestion">
- <xs:sequence>
  <xs:element name="VeridQuestionType" type="tns:VeridQuestionType"
maxOccurs="unbounded" /> 
  </xs:sequence>
  </xs:complexType>
- <xs:complexType name="VeridQuestionType">
- <xs:sequence>
  <xs:element name="VeridTrxQuestionidId" type="xs:string" minOccurs="0" /> 
  <xs:element name="VeridAnswerType" type="xs:string" minOccurs="0" /> 
  <xs:element name="VeridText" type="xs:string" minOccurs="0" /> 
  <xs:element name="VeridChoice" type="tns:VeridChoice"
maxOccurs="unbounded" minOccurs="0" /> 
  <xs:element name="VeridHelpText" type="xs:string" minOccurs="0" /> 
  </xs:sequence>
  </xs:complexType>
- <xs:complexType name="VeridChoice">
- <xs:sequence>
  <xs:element name="VeridChoiceType" type="tns:VeridChoiceType"
maxOccurs="unbounded" /> 
  </xs:sequence>
  </xs:complexType>
- <xs:complexType name="VeridChoiceType">
- <xs:sequence>
  <xs:element name="VeridChoiceId" type="xs:string" minOccurs="0" /> 
  <xs:element name="VeridText" type="xs:string" minOccurs="0" /> 
  </xs:sequence>
  </xs:complexType>

After I generate the stub by axis, the snippet of stub class is following:

public class VeridQuestions  implements java.io.Serializable {
    private java.lang.String veridQuestionSetId;

    private
com.cashedge.common.cewebservices.client.RiskWebService.VeridQuestionType[][]
veridQuestion;
.
.
.
}

When I run the webservice for this stub, I got the following exception:

Can anyone help me to find the clue for this issue ? Thanks
