Web Dynpro Domino Web Service Consumer Problem

Question

Dear All,
We are trying to consume a Web Service on Domino.
The web service is working Fine on webdynpro web service checker (EP perspective, Web Service Checker), but when tested with check and deploy, the Webservice return an error:
"Service call exception; nested exception is: com.sap.engine.lib.xml.parser.ParserException: The empty string is not acceptable for a value of an xmlns:* attribute.(:main:, row:1, col:0)"
It is a simple web service getting a string in input and returning a simple string (xsd string in both cases),
here are the soap messages used:
Input
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tns="http://bespordom.lhoist.net/webserviceagent.nsf/directorywsdl" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns="http://schemas.xmlsoap.org/wsdl/">
  <SOAP-ENV:Body>
    <tnsMethod:getperson xmlns:tnsMethod="uri:Domino">
      <FullName xmlns="" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="xsd:string">Davis</FullName>
    </tnsMethod:getperson>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
response
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <SOAP-ENV:Body>
    <m:getpersonResponse xmlns:m="Domino" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
      <Answer xsi:type="xsd:string">Jim [email protected] Falls1313 Mocking Bird laneNY127842241~</Answer>
    </m:getpersonResponse>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
this information came from the Webdynpro web service checker (or EP web service checker in Netweaver developer studio).
Any Idea will be welcome.

Hello victor I checked,
Unfortunately It is only one input parameter and one output parameter.
Example:
Dividing a number By 2
Example I send the number 10 and the result (xml/string) would be 5.
Input Number as string
Output Result as string
message function divide

When I run it in the Web service Checker with the URL http://bespordom.lhoist.net/divide.nsf/wsdl, it Gives me the correct result and Functionality. Here is the Soap generated on the Web Service checker:

  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
I initialize correctly the Web service and the field number (with new String()) in the component controller.
When I click on the Button divide on the web dynpro interface, I call the executerequest defined in the component controller where I execute the call.
But the response is always the same:
Service call exception; nested exception is: com.sap.engine.lib.xml.parser.ParserException: The empty string is not acceptable for a value of an xmlns:* attribute.(:main:, row:1, col:0)
What can i do or check, or can I debug the soap generated or received by the portal?
Do you see something wrong?
Thank you very much for your help.
