Hi,
Is it possible to call an openid provider from a simple java console using OpenId4Java library ?
Thanks a lot.

Hello
I'm afraid not. According the spec, openid cannot support implicit authentication. Maybe you should try openid connect!

To answer your question:
- It is possible to invoke an OpenID provider from a Java console program utilizing a query-string based request. You can utilize java.awt.Desktop to invoke the URL of the OpenID provider, which will in turn invoke a browser for the user to authenticate. It is not possible, however, to complete the transaction without a corresponding web counterpart to your application to receive assertion once the user has completed authentication.
- A possible solution would be to use OpenId4Java in your client application to create the request and launch the OpenID server, then have a web application receive the OpenID response. This response can be forwarded to the console application by registering a URL handler on your platform with a specific scheme (e.g. myapp://....). Note: Java Web Start is probably the easiest way of handling this type of re-entry into your native app.
The intermediate web server requirement for handling the response could be avoided by using OpenID Connect, assuming that the OpenID Connect server supports non-https:// schemes when registering client applications.
Hope that helps
