Help in forming SOAP message for Bpel process

Question

Hi,
I have a following schema file - UnpackMessage.xsd
<?xml version="1.0" encoding="windows-1252"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.w3.org/2001/XMLSchema/UnpackMessage"
xmlns:tns="http://www.w3.org/2001/XMLSchema/UnpackMessage"
elementFormDefault="qualified">
<complexType name="PackHandlerProcessRequestType">
<sequence>
<element name="instanceId" type="string"/>
<element name="activityName" type="string"/>
<element name="result" type="string"/>
</sequence>
</complexType>
<element name="PackHandlerProcessRequest" type="tns:PackHandlerProcessRequestType"/>
</schema>
and the following wsdl file for a bpel process
<?xml version = '1.0' encoding = 'UTF-8'?>
<definitions name="PackManagerWSDL"
targetNamespace="http://xmlns.oracle.com/PackManager"
xmlns="http://schemas.xmlsoap.org/wsdl/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"

<types>
<schema attributeFormDefault="qualified" elementFormDefault="qualified"
targetNamespace="http://xmlns.oracle.com/PackManager"

</message>
<message name="PackManagerResponseMessage">

</message>
<portType name="PackManager">
<operation name="initiate">
<input message="client:PackManagerRequestMessage"/>
</operation>
</portType>
<portType name="PackManagerCallback">

</operation>
</portType>

</plnk:role>
</plnk:partnerLinkType>
</definitions>
The receive activity in bpel process expects input message "PackManagerRequestMessage" of type "PackHandlerProcessRequestType"
Now on invoking the Bpel process directly by using the console ... the default input to the process looks like this -
<payload xmlns="" xmlns:def="http://www.w3.org/2001/XMLSchema/UnpackMessage"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:type="def:PackHandlerProcessRequestType">
<instanceId xmlns="http://www.w3.org/2001/XMLSchema/UnpackMessage">600</instanceId>
<activityName xmlns="http://www.w3.org/2001/XMLSchema/UnpackMessage">receive</activityName>
<result xmlns="http://www.w3.org/2001/XMLSchema/UnpackMessage">ok</result>
</payload>
and the receive activity gets the following as input (as taken from Flow in bpel console)
<ReceiveInput_initiate_InputVariable>
     <part name="payload" >
          <payload xsi:type="def:PackHandlerProcessRequestType" >
               <instanceId>800</instanceId>
               <activityName>receive</activityName>
               <result/>
          </payload>
     </part>
</ReceiveInput_initiate_InputVariable>
But when i invoke the same process using a SOAP message which looks like
<?xml version = "1.0" encoding = "UTF-8"?>
<SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ns2="http://www.w3.org/2001/XMLSchema/UnpackMessage" xmlns:xsd="http://www.w3.org/1999/XMLSchema">
<SOAP:Body>
<payload xmlns="" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="def:PackHandlerProcessRequestType">
<ns2:instanceId>600</ns2:instanceId>
<ns2:activityName>receive</ns2:activityName>
<ns2:result>OK</ns2:result>
</payload>
</SOAP:Body>
</SOAP:Envelope>
the receive activity now gets the following as input (taken from Flow in bpel console)
<ReceiveInput_initiate_InputVariable>
<part name="payload">
<ns1:instanceId>600</ns1:instanceId>
</part>
</ReceiveInput_initiate_InputVariable>
So i am losing input data. Can someone help me form appropriate SOAP message for this ?
Thanks,

Thanks Marc,
The SoapUI is really useful. The SOAP request as generated by the SoapUI for above case is
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:add="http://schemas.xmlsoap.org/ws/2003/03/addressing" xmlns:pack="http://xmlns.oracle.com/PackManager" xmlns:unp="http://www.w3.org/2001/XMLSchema/UnpackMessage">
<soapenv:Body>
<pack:initiate>
<payload>
<unp:instanceId>800</unp:instanceId>
<unp:activityName>receive</unp:activityName>
<unp:result/>
</payload>
</pack:initiate>
</soapenv:Body>
</soapenv:Envelope>
and the input received at BPEL was as expected.
Thanks a lot.
Srini.
