Accessing SOAP Headers in BPEL

Question

Hi All,
I have been trying to access a custom soap header in BPEL but in vain.
I have the header like this in my wsdl
    <wsdl:message name="doTransactionRequest">
        <wsdl:part name="part1" element="tns:doTransaction"/>       
    </wsdl:message>   
    <wsdl:message name="doTransactionHeader">
        <wsdl:part name="teamName" element="tns:myName"/>
    </wsdl:message>
    <wsdl:message name="doTransactionResponse">
        <wsdl:part name="part1" element="tns:doTransactionReply"/>
    </wsdl:message>
    <wsdl:binding name="RequestHandlerProxySoapBinding" type="tns:RequestProxyPortType">
        <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
        <wsdl:operation name="doTransaction">
            <soap:operation soapAction=""/>
            <wsdl:input name="doTransactionInput">
                <soap:header message="doTransactionHeader" part="teamName" use="literal"/>
                <soap:body use="literal"/>
            </wsdl:input>
            <wsdl:output name="doTransactionOutput">
                <soap:body use="literal"/>
            </wsdl:output>
        </wsdl:operation>
    </wsdl:binding>In BPEL I have a corresponding header variable defined for the header "teamName".
Now how do I tell BPEL "receive" to copy the incoming header to this variable ? There is no parameter called "headerVariable" or so for the receive element. As far as I understand, when the soap header "myName" comes, it is copied as a property in the normalized message. Now I need to tell BPEL service engine some how to copy the property to the header variable. But I don't know how to do that.
I Really need some help. Thanks in advance.
best regards,
bala

I would try defining the soap:header under the <operation> description in your .wsdl
to look something like this:
<Input>
<soap:header message="tns:SessionHeader" part="SessionHeader"/>
<soap:body message="[yourprocess]RequestMessage"/>
</Input>
Then create a variable of the sessionHeader message type and assign it in the adapters tab.
You'll probably also need to add this namespace to your wsdl:
xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/
I haven't tested this but it should get you on the right track...
