ofbiz login through rest services

[Ankit]

Hi All,

I have a requirement to call rest service in ofbiz. As REST service call then first of all check authentication, if user is not logged in then redirect his/her to authentication page.

I looked into https://cwiki.apache.org/OFBIZ/export-service-using-rest.html.

I mostly show that the authentication check in request-map in controller and its redirect from there.
My question is how can i redirect to the user as he/she is not logged in from services ? or there is other way to redirect it on login ?

Thanks,
Ankit
