Place an SOAP envelope Header in a SOAP RPC call

Hello,

does anybody know who to place a Soap Envelope Header in a SOAP RPC Call?
All I place in reqParms Parameter of the soapRPC flow serviced appears in the Body, but I have to send a SOAP Header to a Websphere Server, otherwise the server rejects my request.

Thanks
Matthias
