9.4.2. Initializing actor IDs

We always need to know which user is currently logged in. jBPM recognizes users with their actor ID and group actor ID. We specify the current actor IDs with the built-in Seam component, actor:
@In Actor actor;

public String login() {
  ...
  actor.setId( user.getUserName() );
  actor.getGroupActorIds().addAll( user.getGroupNames() );
  ...
}
