Hi,

The problem you are experiencing is the fact the Frontend.getInstance() is a 
frontend (client, which get compiled to javascript) class, and the servlet is 
on the server side where this class is not defined (as it is frontend only). 
Maybe if you could explain what you are trying to do we could assist better.

We have a mechanism of getting the REST api session on the front end when you 
log in. On the backend you don't really need that, since you are on the 
backend. So your question sort of confuses me at this point.
