Hi,=0A=A0=0A=A0=0AI'm trying to work with=A0an existing SOAP/XML web servic=
es that is working fine with clients written in Java and .Net. Any help/ide=
a is greatly appreciated!=0A=A0=0A=A0=0AI need the soapClient to send the f=
ollowing XML request. I tested this request with a=A0third-party tool and=
=A0made sure it works fine:=0A=A0=0A<soapenv:Envelope xmlns:soapenv=3D"http=

=0A=A0=0A=A0=0AThe "credential" is used for authentication and the "orderPa=
