WSIF - HTTP Provider

Hi WSIF Team!

We are a team of students of University Furtwangen. In one of our 
lectures it's called SOA we should analyse WSIF its features and 
concepts. During our research we getting interested in writing our own 
provider. After some discussion we planed to write a provider for HTTP. 
After reading your documentation about the provider mechanism and wsdl 
extension handling, we've started to implement a http provider.
Our idea is to describe a http request as a webservice using POST or GET 
HTTP requests. We discused, that in first step of implementation only 
the wsdl message parts are transmitted to the http server, using POST or 
GET. (Example: GET http://abc.abc.com/Abc?part1=value1&part2=value2).

By now, we identified some unanswered questions:
How to handel a complex message structure?
What is the stub if wsif is not used with dynamic ws invocation?
What is the wsdl output message for the http response (normally a HTML 
page)?

We would glad be if you (the wsif comunity) are interested in this 
provider and its sources.
We are not familiar in taking part in open source projects so far. we 
appreciate any help or suggestions.

We are thankful in advance.
Alex, Gerold, Vicky
