Missing operation for soapaction and body element null with soap version soap 1.1

Hi, 
I've been trying to create a Mock webservice using SOAPUI and deploy it as war file and host it using weblogic.  I've following the instruction from:  http://www.soapui.org/getting-started/mock-services.html and the tested the mock webservice that ran on SOAPUI.  It works fine when SOAPUI hosted the mock webservice but I have a tough time trying to get the deployment of the war file using weblogic12c to work.  The mock webservice would work the first time on the serverbut subsequence requests get a blank response. I get the following Errors from the server:
"missing operation for soapaction and body element null with soap version soap 1.1"
I tried the following solutions but no work
1) Set to "True" the Mock Properties: Match Soap Version, Require Soap Action, Dispatch Responses.
2) Disable the "Log wire content of all mock requests" found in HTTP Settings.
3) Try another version of soapui , such as 5.2.0 and 5.5.0
4) Setting the soapAction and body (in raw request).

Attached a document with with soapui mock project.  Please have a look at it and let me know if you see where I my mistakes maybe. 

thank you for your time.
Regards.
