SOAP adapter with AXIS protocol

Hi All

Can you please help me in knowing when to use the Axis transport protocol.

Sender : Servlet(Axis),Task (Axis),NonTask(Axis)

Reciever : http(Axis)SMTP(Axis),File(Axis),Generic(Axis)

when we need to use which protocol as i know it depends on the scenario .

Please help me to understand , if people have already used this transport protocol and in which type of scenarios.

Regards

Sandeep
