"Mismatched number of parameters passed to routine <

I have complete setup for web service calling in my environment. When I tried with SOAP UI it works. In my OE environment I have generated the Operation Index and other stuffs using the command like this

call %DLC%\bin\bprowsdldoc -show100style -b %WSDL_LOCATION%\TMSOnline.wsdl %WSDL_GEN_DOC%\TMSOnline

The document shows three parameter should pass in operation procedure 
1) <oLogin>
          -----
    <oLogin>
2) <oOperation>
          -------
    </oOperation>
3) This is for Outputting the response received.

While In SOAP UI both parameter clubbed like this in single request
<addOperation>
      <oLogin>
          -----
      <oLogin>
      <oOperation>
          -------
      </oOperation>
</addOperation>

Above two approaches working fine one with two parameter in OE environment and Other with single request in SOAPUI.

But I want that in OE environment this should work with passing Single Request  not by passing two separate Request Parameter. Can any body tell me if there is any way to do this thing in OE environment?

Thanks,
