How can I define AuthenticationCallback when trying to access access token from refresh token in Adal4j?

Question

I'm using Adal4j Java library.I already have a refresh token but would like to get access token based on the refresh token.

I have the following code and I couldn't figure out how to define AuthenticationCallback

     ExecutorService service = Executors.newFixedThreadPool(1);
            AuthenticationContext context = new AuthenticationContext(authority, true, service);

context.acquireTokenByRefreshToken(resultFuture.get().getRefreshToken(), new ClientCredential("8a6....4b6", "J5....EU="), ?????? );

How do I define AuthenticationCallback ?

Answer 1

We need to implement the AuthenticationCallback interface. Here is a code sample for your reference:

import com.microsoft.aad.adal4j.AuthenticationCallback;
import com.microsoft.aad.adal4j.AuthenticationResult;

public class MYAuthenticationCallback implements AuthenticationCallback
{
    public void onFailure(Throwable arg0) {
    // TODO Auto-generated method stub  

    }

public void onSuccess(AuthenticationResult arg0) {
    // TODO Auto-generated method stub
    System.out.println(arg0.getAccessToken());
    }
}
