How to retrieve client's username at WS Impl class?

[Karthik krishnamurthy]

Hi,

I have Authenticated the "username" field by implementing New
Authentication Handlers.
In the web service implementation class, I wish to retrieve the username
that was successfully authenticated.

Could anyone suggest me how I could do this?

I'm generating the code using WSDL2Java. Is it possible to get some client
side information at the Skeleton class?

Thanks & Regards,
Krish.
