Namespace for Webdynpro ABAP in EP

Hi Experts,

I am new to EP and Webdynpro ABAP.

In my case, I would like to integrate the Webdynpro application to the iview in EP. But I don't know what is the namespace in my application.

Below is the some information of my Webdynpro application:

URL: http://server:port/sap/bc/webdynpro/sap/zwd_00_simple_application

Package: ZHR_ESS

Please let me know what should I put in the namespace textbox when creating the iview for my Webdynpro application.

Million thanks.

Kelvin
