Multiple Login endpoints in Jetty + Jersey

I'm building an application with an API layer. To access an API endpoint the request should carry a valid token. The token is generated and assigned upon successful authentication of a user. A user can be authenticated through multiple ways: DB username/password check, FB, LDAP and so on.

I currently have a ServletContextHandler executing a Jersey Servlet Container, serving endpoints /api/*.

Aim is to add login endpoints: /login/fb, /login/myapp, login/ldap and I'm unsure where exactly it fits in. Should I add these as other endpoints in the jersey servlet or add a new custom servlet to handle these logins. Was wondering if there is another way of handling such multiple login endpoints in Jetty.

I do not use any xml to configure Jetty. The existing filters were configured through annotations and I would like to continue this way.

Haven't used Jetty before, not sure about the suitable architecture pattern applicable to this case.
