Change namespace in generated WebService

Question

Hello experts,
i have to provide a webservice with three methods for an external Client.
So i created three functions in a function group. From the function group i autocreated my webservice with the wizzard. I changed the external/internal mapping properly, activate the webservice and create with soamanager a service and an endpoint and so on...
When i create a client with the autogenerated WSDL from the WebService, i can call and reach the autogenerated Webservice from this client.
The problem is: The external client cant reach our webservice. We have solved all problems with firewalls and certificates. The remaining problem is the namespace. The external clients request (we cant change it and have to provide a suitable webservice) with the namespace "urn:extnamespace" cant reach our servicepoint (error "service >extnamespace:Connect< not supported") :
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:extnamespace="urn:extnamespace">
<SOAP-ENV:Body>
  <extnamespace:Connect>
    <token>123456</token>
  </extnamespace:Connect>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
From our test- client we use successfully this with the namespace "urn:sap-com:document:sap:rfc:functions"::
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:extnamespace="urn:sap-com:document:sap:rfc:functions">
<SOAP-ENV:Body>
  <extnamespace:Connect>
    <token>123456</token>
  </extnamespace:Connect>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
The wizzard have automaticaly generated the namespace "urn:sap-com:document:sap:rfc:functions". The external Client use another namespace. We have no option to change the external client or request of it. We need to provide a suitable WebService which use the same namespace.
We found no possibility to say the generation wizzard to use another namespace. Also we found no possibility with soamanager to change it.  When we change the namespace in XSLT-Transformation with STRANS and call the WebService from our test client, we get allways the error "service >extnamespace:Connect< not supported".
The following links seems to be good on first sight, but dont help us:
[Changing SOAP Namespace for Web Service;
[service.sap.com/notes]   sap note 853824
If there is no way to change the namespace, we have to create the webservice manually. Is there a suitable example for this job available?
Greetings & thank you very much for your help!

Answer 1

We have created a server interface in XI with the wsdl excepted by the external client. Then created a server proxy with this interface  in our sap system. Then we have implemented the generated methodes by calling existing functions. It works fine.
Thanks a lot!
