XML : how to specify order for the

I have a wsdl file like this:

  <message name="IntegrationQuery4ThirdRequest">      <part name="SessionMessage" element="tns:SessionEntity"/>      <part name="IntegrationQuery4ThirdRequestMessage" element="tns:IntegrationQueryRequest4Third"/>       </message>    

The elements SessionEntity and IntegrationQueryRequest4Third are defined in the xsd file

But my auto generated stub file (created using WSDL2Java) has the order of parameters as

  <cvas:IntegrationQuery4Third>      <cvas:IntegrationQueryRequest4Third></cvas:IntegrationQueryRequest4Third>      <cvas:SessionEntity> </cvas:SessionEntity>  </cvas:IntegrationQuery4Third>    

But the parameter order required is

  <cvas:IntegrationQuery4Third>      <cvas:SessionEntity> </cvas:SessionEntity>      <cvas:IntegrationQueryRequest4Third> </cvas:IntegrationQueryRequest4Third>  </cvas:IntegrationQuery4Third>    

Due to the wrong parameter order, Iam getting an exception like this:

The interface parameter is wrong: There has 2 XML Validation Errors 1:[Expected element 'SessionEntity' instead of 'IntegrationQueryRequest4Third' here in element IntegrationQuery4Third]. 2:[Expected element 'IntegrationQueryRequest4Third' before the end of the content in element IntegrationQuery4Third].

What can I do to change the order of parameters??
