Sidhu,
If you are just doing HTTP stuff (i.e. not web-services), you can use the HTTP adapter on both the Send and Receive ports.
If however, you decide to use web-services, you will need to expose either an orchestration or schema as a web-service (using the SOAP adapter) on the receive side and consume with a Send Port that is also configured to use the SOAP adapter (invariably the Send Port would be a solicit-reponse port: it sends a request and receives a response).
Hope this helps, Nick.
