Hi,

I want to do "Invite Friends" functionality in my application.
My requirement is like for the particular user(prasad.s@gmail.com), i neet get a contacts list associated in gmail account.

So i need to connect to gmail internally and i need to display the contact list of the user(prasad.s@gmail.com) in my appllication.

I need to do it for Yahoo mail also.

Any API?.
I got "jgmail" and "g4j" API but there is no documentation or examples to do.

Please help me out.

Thanks in advance,
Prasad.
