Comsume Web Service via ABAP SAP 4.7

Question

Hello Experts
We wanted use an ABAP program to call a web service.  We were only given the target WSDL file.  Not sure what to do with this and what information can we get from this. 
As I checked, the format is different from the conventional web service I found in the blogs.  Usually the WSDL URL is format below.
http://www.webservicex.net/airport.asmx?wsdl
and you can see and test the services from this URL http://www.webservicex.net/airport.asmx
But in our case, this the WSDL URL is below.
http://<host>/dd10/services/shipRSS?wsdl
and we cannot see and test service from http://<host>/dd10/services/shipRSS this is what we are getting.
"shipRSS
Hi there, this is an AXIS service!
Perhaps there will be a form for invoking the service here..."
Having this kind of WSDL, can we still create an ABAP program that can consume this?  Is there difference in the programming and parameters.  Currently we are using the program template from this blog /people/durairaj.athavanraja/blog/2004/09/20/consuming-web-service-from-abap as we are only running on SAP 4.7 but it seems not to be working.  Any thoughts?
Thank you very much!

Hi Andrei,
We did the changes in the program and we seem to have made some progress here.  Here are the test results now.  
Test Soap
>> Starting...
>>
>> TEST: SOAP call to method STFC_CONNECTION
>>
>> Result of SOAP call
   echotext =
   resptext =
<< ...Done
Here is an excerpt of the program of which parameters are inputted.  We are suppose to send an XML string.  We have not made much changes in the sample program except the one you highlighted to us before.  But if there are any concerns it will on the part where to construct soap request document which is shown below.  If it is not too much to ask, would you help us check the parameters if they are correct.  Thank you very much.  You've been very helpful.
