How to pass header Variables along with body

Question

Hi,
Here I am invoking siebel web service which is wsdl(SOAP) based web service. I tested it through sopaUI and it is working fine for me as I am getting proper response. here is the input payload structure.
Note: it is running on HTTPS, so SSL has been applied to this  site.
it is loading as http not https. For every operation when we make a request, we are changing the link to https and submitting it. Then it is working for us.
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns="http://www.xxxxxx.com/2005/">
   <soapenv:Header>
      <ns:AuthorizationToken>
         <ns:Token>userName;Password</ns:Token>
      </ns:AuthorizationToken>
   </soapenv:Header>
   <soapenv:Body>
      <ns:WEBIndividualGet>
         <ns:key>{6D803C43-3917-4C99-91F3-003EB9E16E1F}</ns:key>
      </ns:WEBIndividualGet>
   </soapenv:Body>
</soapenv:Envelope>
Now I created the bpel projects like this.
Step 1:- in the xsd, I created two elements types
<xsd:element name="UsernameToken" type="xsd:string"/>
    <xsd:element name="PasswordText" type="xsd:string"/>
Step 2:- Then I created the WSDL in respect to above elements
<!-- Message section -->
<wsdl:message name="WEBAutTokenOut">
  <wsdl:part name="userName" element="netObj:UsernameToken"/>
  <wsdl:part name="passWord" element="netObj:PasswordText"/>
</wsdl:message>
<wsdl:portType name="portTypeName">
  <wsdl:operation name="operationName">
  <soap:operation soapAction="sopaAction">
  </soap:operation>
   <wsdl:input message="netSer:SvcRequestMessage">
    <soap:header message="netSer:WEBGetAutToken" part="userName" use="literal"/>
    <soap:header message="netSer:WEBGetAutToken" part="passWord" use="literal"/>
   </wsdl:input>
   <wsdl:output message="netSer:SvcResponseMessage">   
    <soap:header message="netSer:WEBAutTokenOut" part="userName" use="literal"/>
    <soap:header message="netSer:WEBAutTokenOut" part="passWord" use="literal"/>
   </wsdl:output>
  </wsdl:operation>
</wsdl:portType>
Step 3:- and My Bpel looks like
<!--Variable Declaration -->
<variable name="customHeaderVar" messageType="netSer:WEBGetAutToken"/>
    <variable name="customOutputHeaderVar" messageType="netSer:WEBAutTokenOut"/>
<sequence name="main">
<receive name="receiveInput" partnerLink="xxxxxxx"
             portType="netSer:xxxxxxxxxxx" operation="xxxxxx"
             variable="inputVariable" createInstance="yes"
            bpelx:headerVariable="customHeaderVar"/>
<assign name="AssignHeaderVariables">
      <copy>
        <from expression='"username"'/>
        <to variable="customHeaderVar" part="userName"
            query="/ns2:UsernameToken"/>
      </copy>
      <copy>
        <from expression='"soa1234"'/>
        <to variable="customHeaderVar" part="passWord"
            query="/ns2:PasswordText"/>
      </copy>
    </assign>
<invoke name="Invoke" inputVariable="xxxxxxxxxxxxxxxx"
            outputVariable="Invoke_OutputVar"
            partnerLink="xxxxxxxxxxx" portType="ns1:XMLSoap"
            operation="WEBGet" bpelx:invokeAsDetail="no"
           bpelx:inputHeaderVariable="customHeaderVar">
            bpelx:outputHeaderVariables="customOutputHeaderVar"/>
Note:  When I am hitting siebel web service it is giving some out put, The output it self has header variable. so that is reason am added outputHeaderVariables.
< Here we have Transformation Activity >
<reply name="replyOutput" partnerLink="xxxxxx"
           portType="netSer:xxxxxxx" operation="WEBGet"
           variable="outputVariable"
           bpelx:inputHeaderVariable="customOutputHeaderVar"/>
That's about my project. But when test this service Am getting error. below is the error details.

Could you please help me out.
Thanks,

Answer 1

The UserNameToken and the Password variables should be created based on the schema http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd
