[Axis 2] : Newbie question on Attachment

[Ramkumar.Sakthivel]

Hi Everyone,   My requirement is, I have to call a web service by sending an attachment. I would like to know which implementation is better (SwA/MTOM)?   Could someone provide an expert advice on this?   I am using Axis2.   Your response is much appreciated.   Thanks in advance,   Ramkumar
