Hi everyone,

I'm new to SSO/Open ID Connect authentication. I got a request to implement this mechanism for an application, and found pac4j and keycloak. From what I see so far keycloak has the better documentation and might fit my needs better.

Now my main issue is to get a working example so I can actually play around with it.
So far I wasn't able to find a way to manually trigger a redirect of the user to the authorization provider.
Is there any good Java example that is basically "vanilla" Java, that shows for example a single servlet with an executable main method, without any need for a specific webserver?
This would help greatly in understanding how keycloak works and how to use it.

Thanks in Advance
