Thanks a ton Paul. This does clear quite a few things.
Will get back to you guys, if I need some more clarifications.

Thanks again. Keep up the good work.

The RelpyTo stuff is part of the WS-Addressing spec. Its a prereq for 
WS-Eventing. I don't know if gSOAP implements WS-Addressing, but if you 
want a toolkit that does, you can try Axis2/C and WSF/C:
