JAX-RS and Authentication

[B P, modificado 6 Anos atrás.]

Here is an example of JAX-RS services inLiferay:

Can you please explain to me how to make these web services require authentication? Pardon me, but I'm brand new to Liferay and JAX-RS, so maybe it's obvious, but I'm still learning. It seems anyone can call these web services (i.e. a guest). How do I change it so that basic authentication is needed to call these services?

Thanks!

You can use Service Guard:

Thanks! I'm still confused about the implementation.

I want the native mobile app to present the user with a login screen then I want to authenticate that user against an LDAP server. After the user has been authenticated then all subsequent REST service calls from the mobile app will be authenticated. Typically, this seems to be done through OAuth2, correct? I don't want to use OAuth2. Can I use basic authentication or cookie based authentication? How would that work with the Service Gaurd library?
