Error when setting dynamically the target URL in receiver SOAP Adapter

Question

Hi,
I'm setting dynamically (from the mapping) the target URL in the receiver SOAP adapter:
String url = "http://mosxd30:50000/XISOAPAdapter/MessageServlet?senderParty=&senderService=DUM&receiverParty=&receiverService=&interface=SI_OA_CustomInvoiceData&interfaceNamespace=urn:repsol.com:laboratory:firma";
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/SOAP", "TServerLocation");
conf.put(key, url);
The receiver adapter fails with:
"invalid content type for SOAP: TEXT/HTML; HTTP 401 Unauthorized"
Reading weblogs, etc, the most probable cause for this is a wrong target URL, but then what I did was to set it as a fixed URL in the C.Channel, and it worked, so the URL is fine.
In the communication channel, I'm using "Configure user authentication", with a user and password, and what I think it's happening is that if I use another different URL dynamically, the channel is ignoring the user authentication settings.
Any ideas?
Thanks

I forgot to say that I've checked the SAP note "FAQ Soap adapter", and it says:
Q: I get an authorization error "401 Unauthorized" from the adapter's servlet. What went wrong?
           A: The adapter's servlet is protected by default. You must use one of the user names assigned in security role xi_adapter_soap_message for component XISOAPAdapter. Please consult the documentation for Visual Administrator to view and change the security setting.
           The user authentication of the SOAP adapter is not part of the SOAP adapter but of the web container of the J2EE engine. The default authentication setting is defined in the web.xml descriptor file of the SOAP dapter web application. This setting may be modified from Visual Administrator with some restriction. Please refer to the security documentation for the J2EE engine.
           Please note that 710 onwards there is no Visual Administrator instead the Netweaver Administrator is to be used to assign the roles to the user to access the SOAP adater servlet.The user must be assigned one of the following roles SAP_XI_IS_SERV_USER, SAP_XI_APPL_SERV_USER, SAP_XI_DEVELOPER_J2EE, SAP_XI_ADMINISTRATOR_J2EE.
The target URL is a sender soap adapter (the result of one interface is sent to another one via soap adapter), and it's this one which is complaining because of the authentication I think. But I don't know why it's ignoring the user authentication flag I'm using.
