Finding the Logged-in User in EP

Hi All,

I want to know the login-details(user-id) of the EP user from my Web-Dynpro Application.

My Web-Dynpro is running in External J2EE engine and is called in EP using URL ivew template.

Is there anything like request or resposne(like jsp) in webdynpro ?

Can anyone help.

Thanks in Advance
