Ah, I was wondering whether you were using the message encoder
here...<br>

Yes, you might be able to do something like that, but please,please
don't do that in the IdP. :-)<br>

Yes, the HTTPSOAP11Encoder first attempts to locate an
already-constructed Envelope in the MessageContext like so:<br>
<br>
<tt> protected Envelope getSOAPEnvelope() {</tt><tt><br>
</tt><tt> return
getMessageContext().getSubcontext(SOAP11Context.class,
true).getEnvelope();</tt><tt><br>
</tt><tt> }</tt><br>
<br>
<br>
So if you just populate an Envelope instance there in that
subcontext before calling the Encoder, that should work. It will
also re-use the Body instance that is there in that Envelope. So
just doing that should give you a localized solution for this.<br>
