SOAP call - how?

Hello all,
I am quite new to Talend but it looks very promising.
However, trying to implement a simple soap call (I'm using TOS 4.0.0 java, but could just as well use perl) I don't see how I should implement the soap call to as such
<?xml version="1.0" encoding="UTF-8"?>
<SOAP:Envelope xmlnsSmiley FrustratedOAP-ENC="" SOAP:encodingStyle="" xmlnsSmiley FrustratedOAP="" xmlns:xsi="" xmlns:xsd="">
<logon xmlns="">
into the tWebServiceInput component.
two problems: I don't see what the "method" (Asked for in the component Basic Settings) is - could it be Logon?
Also, I don't see where I should put the SOAP Envelope.
Is tWebServiceInput the right component for this? tXMLRPCInput offers me the same questions.
With regards,
