Call authenticate service in EJB

Hi Experts

I'd developed a ejb project, and in this project i imported a service from esworkplace. I need to authenticate when i call this service, but i don't know how can i do this. I think is necessary http authentication.

I created a service group, but didn't work.

I use NW 7.1 EHP1.

Someone can help me to resolve this?
