How to Invoke service using HTTP POST in BPEL?

Question

I have a client using .net service with a web page http://.../httpreceive.aspx which is invoke through an http post. How can we post xml message using http post to the url in BPEL. Are there any documentation on doing this? Will this require writing a java class to do an http post the xml message to the url?

I created a wsdl with the http-binding to do a HTTP Post and I'm getting a com.collaxa.cube.ws.wsif.providers.http.WSIFOperation_HTTP@1ac9964 : Could not invoke 'process'; nested exception is: java.lang.NullPointerException.
Here's my wsdl with the binding:
