Thank you for your replay, I had a look at it. They are submitting the form as following:
Now I know that this works but the point is that I basically don't have a web server, just web services. So instead of submitting a form I read the data, wrap it into a soap message and issue a web service call. I can add web services at will but I want to avoid having to program on the web server (the web service communicates with an application server).
So I guess what I need to do is to find out how to read the CONTENTS of the file into a variable so I can submit the data to the web service.
