Hmm, looking at the fixes you've done, it should work on debian also. I would 
be very interested in testing results also from debian. Ideally, it should 
not matter which linux installation the service is running on. However, we 
cannot support any other platform (like windows for example) at the moment.

Yes, the WSDL is a problem. Jochen considered this in his email informing 
about soapUI:
"[...]
There are some problems with soapUI that are more or less perfSONAR/NMWG 
specific. NMWG's request/response cannot be described using WSDL, like it 
should normally be done when using web services. Please note: My knowledge 
about SOAP and WSDL is far from being perfect! If you know how to describe a 
perfSONAR/NMWG service using WSDL or if you already have a WSDL file, please 
inform me about it! Having one will make functional testing for the described 
service possible in a few hours!

On the other hand it's no great problem to work around the WSDL problem. WSDL 
cannot (yet) use RNC/RNG for schema description, but both can be converted to 
XML Schema (XSD) using e.g. trang. Since XML Schema is not as powerful as 
Relax-NG I have some problems at the moment. [...]"

By default, the service is running on port 8090. (You can change this in the 
configuration file [see configuration file manual of the documentation] or by 
starting the service with --port=<portnumber>).
You should also provide /services/MP/BWCTL as URI in your request.
I think, I should add a section about using the service in the installation 
documentation.

First of all, you should ensure that the service is working correctly when 
receiving the example request files (see interface specification document). 
If this is the case, try to get errors :)

Probably Michalis can explain funcitonal testing in general to you. If you 
have specific questions about BWCTL feel free to ask me. For questions on 
soapUI Jochen knows it best.
